 What is File Management in fisheries?
 Every file related to fish various field (marine, freshwater,
estuary) on your computer is part of a complex,
hierarchical system made up of directories and
subdirectories. The process of naming, storing, and
retrieving those files in an organized way is the basis of
file management in fisheries management and when done
efficiently, can save a tremendous amount of time and
headaches.
 Imagine a large fisheries management organization with
several terabytes of valuable data stored on their servers.
Now imagine trying to find one specific file from fish data
on these servers when you only have minutes to spare.
What is file management system?
A file management system is a type of software that
manages data files in a computer system.

Hierarchical file system
 A hierarchical file system is how drives, folders, and
files are displayed on an operating system. In a
hierarchical file system, the drives, folders, and files
are displayed in groups, which allows the user to see
only the files they're interested in seeing. For example,
in the picture the Windows directory (Windows)
folder hierarchy that contains the System32, Tasks, and
Web folders. Each of these folders could have
hundreds of their own files, but unless they are opened
the files are not displayed.
File type
 Document file
 ( ms word file, excel,
database)
 Video file
 Audio file
 Image file
 Application file
Video file
Audio file
Image file
Naming files
 Naming conventions are rules which enable the
titling of electronic and physical folders, documents
and records in a consistent and logical way.
File name restrictions
•The following reserved characters:
< > : " /  | ? *
Remove spaces from file names or use
punctuation such as underscores and hyphens
to separate words e.g.
“AHRC_TechnicalApp_Response20120925.docx”
or “AHRC-TechnicalApp-
Response20120925.docx” rather than “what we
got back from funders about the data stuff.docx
File name restrictions
 The New Technology File System (NTFS) in Windows
has naming conventions for a file: a base file name and
an optional extension, separated by a period.
•Integer value zero, sometimes referred to as the ASCII NUL
character.
•Characters whose integer representations are in the range 1-31.
•Any other character the target file system does not allow.
• Use a period as a directory component in a path to
represent the current directory. For example, .temp.txt.
File name restrictions
 • Use two consecutive periods (..) as a directory
component in a path to represent the parent of the
current directory, for example ..temp.txt. For more
information, see Paths.
 • Do not use the following reserved names for the
name of a file:
 CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4,
COM5, COM6, COM7, COM8, COM9, LPT1, LPT2,
LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also
avoid these names followed immediately by an
extension; for example, NUL.txt is not recommended.
Rename file or folder
 As with other file managers, you can use Files to change the
name of a file or folder.
 To rename a file or folder:
 1. Right-click on the item and select Rename, or select the
file and press F2.
 2. Type the new name and press Enter or click Rename.
 You can also rename a file from the properties window.
 When you rename a file, only the first part of the name of the
file is selected, not the file extension (the part after the last .).
The extension normally denotes what type of file it is (for
example, file.pdf is a PDF document), and you usually do not
want to change that. If you need to change the extension as
well, select the entire file name and change it.
Rename file or folder
Common problem of naming
 The file name is already in use
 You cannot have two files or folders with the same name in the same
folder. If you try to rename a file to a name that already exists in the folder
you are working in, the file manager will not allow it.
 File and folder names are case sensitive, so the file name catla.txt is not
the same as catla.txt. Using different file names like this is allowed,
though it is not recommended.
 The file name is too long
 On some file systems, file names can have no more than 255 characters in
their names. This 255 character limit includes both the file name and the
path to the file (for example, /home/wanda/Documents/work/fims –
thesis report /…), so you should avoid long file and folder names where
possible.
Problem
 The file name is already in use • The file name is too long
max 255 characters
File extensions
Word processor and text file
formats by file extension
• .doc and .docx -
Microsoft Word
file • .pdf - PDF file
Presentation file formats
by file extension
.ppt - PowerPoint
presentation • .pptx -
PowerPoint Open
XML presentation
Data file extensions
.dat - Data
file
Font file extensions
.fnt - Windows font file .otf
- Open type font file
Image file formats by file extension
.jpeg or .jpg - JPEG image
.png - PNG image
Video file formats by file extension .mp4 - MPEG4 video file
 Icon view
 To sort files in a different order, click the view options button in the toolbar
and choose By Name, By Size, By Type, By Modification Date, or By Access
Date.
 As an example, if you select By Name, the files will be sorted by their names,
in alphabetical order. See Ways of sorting files for other options.
 You can sort in the reverse order by selecting Reversed Order from the
menu.
 List view
 To sort files in a different order, click one of the column headings in the file
manager. For example, click Type to sort by file type. Click the column
heading again to sort in the reverse order.
 Name: Sorts alphabetically by the name of the file.
 Size: Sorts by the size of the file (how much disk space it takes up). Sorts
from smallest to largest by default.
 Type: Sorts alphabetically by the file type. Files of the same type are
grouped together, then sorted by name.
 Last Modified: Sorts by the date and time that a file was last changed. Sorts
from oldest to newest by default.
Icon views
• What kind of folder do
you want?
Optimize this folder for
general item , picture
,music video & Documents
 You can change the folder
icon.
 If you change the icon, it
will no longer show a
preview of the folder’s
contents.
File copying
• creation of a new
file
• content as an existing file
 Computer operating systems include file copying methods to
users, with operating systems with graphical user interfaces
(GUIs) often providing copy-and-paste or drag-and-drop
methods of file copying.
File deletion
 File deletion is a way of removing a file from a computer's file
system.

Viewing and sorting files and
folder
Sorting Files
 Sort files and folders
 You can sort files in different ways in a folder, for
example by sorting them in order of date or file size.
See Ways of sorting files below for a list of common
ways to sort files. See Views preferences in Files for
information on how to change the default sort order.
The way that you can sort files depends on the folder
view that you are using. You can change the current
view using the list or icon buttons in the toolbar.

Keep file safe
 Keep It Locked
 Create a Secure Password
 Back up file
 Keep It Locked
 Although this might seem obvious, many people think since
they live in a thief has trouble getting into your house, they
may move on to an easier target with unlocked doors, so locking
the door of the room where you store the file when not in use
could prevent unexpected loss from a formerly trusted
acquaintance.
 i.e., Such as fish data
 Create a Secure Password
 Make it difficult for a thief to discover your password by being
creative.
 Figure out something you will easily remember but that doesn't
contain obvious words or dates, such as family or pet names and
birthdays or addresses.
 Make sure it is at least eight characters or longer and uses a
combination of upper and lowercase letters, numbers, and
special characters (for example, !@#$%).
 Back up file
 When computer files contain information that is
extremely important, a back-up process is used to
protect against disasters that might destroy the files.
Backing up files simply means making copies of the files
in a separate location so that they can be restored if
something happens to the computer, or if they are
deleted accidentally.
 The fish of bangladash-SIS-SRS backup
 The Fish-red list-exoticfish backup
 -method automatically makes three back-ups; the
grandfather file is the oldest copy of the file and the son
is the current copy.

Degonto, File management system in fisheries science

  • 1. Presented by : Degonto Islam(ASH1802044M) Department of fisheries & Marine Science Noakhali Science & Technology University
  • 2.  What is File Management in fisheries?  Every file related to fish various field (marine, freshwater, estuary) on your computer is part of a complex, hierarchical system made up of directories and subdirectories. The process of naming, storing, and retrieving those files in an organized way is the basis of file management in fisheries management and when done efficiently, can save a tremendous amount of time and headaches.  Imagine a large fisheries management organization with several terabytes of valuable data stored on their servers. Now imagine trying to find one specific file from fish data on these servers when you only have minutes to spare.
  • 3. What is file management system? A file management system is a type of software that manages data files in a computer system.  group files  office documents  records  Create, modify, copy, delete and other file operations
  • 4. Hierarchical file system Fisheries sustainability Socioeconomic attributes Biological attributes economy society Biological conservation Biological production GVA RBER EMPL WAGE F SSB Y D
  • 5. Hierarchical file system  A hierarchical file system is how drives, folders, and files are displayed on an operating system. In a hierarchical file system, the drives, folders, and files are displayed in groups, which allows the user to see only the files they're interested in seeing. For example, in the picture the Windows directory (Windows) folder hierarchy that contains the System32, Tasks, and Web folders. Each of these folders could have hundreds of their own files, but unless they are opened the files are not displayed.
  • 6. File type  Document file  ( ms word file, excel, database)  Video file  Audio file  Image file  Application file Video file Audio file Image file
  • 7. Naming files  Naming conventions are rules which enable the titling of electronic and physical folders, documents and records in a consistent and logical way.
  • 8. File name restrictions •The following reserved characters: < > : " / | ? * Remove spaces from file names or use punctuation such as underscores and hyphens to separate words e.g. “AHRC_TechnicalApp_Response20120925.docx” or “AHRC-TechnicalApp- Response20120925.docx” rather than “what we got back from funders about the data stuff.docx
  • 9. File name restrictions  The New Technology File System (NTFS) in Windows has naming conventions for a file: a base file name and an optional extension, separated by a period. •Integer value zero, sometimes referred to as the ASCII NUL character. •Characters whose integer representations are in the range 1-31. •Any other character the target file system does not allow. • Use a period as a directory component in a path to represent the current directory. For example, .temp.txt.
  • 10. File name restrictions  • Use two consecutive periods (..) as a directory component in a path to represent the parent of the current directory, for example ..temp.txt. For more information, see Paths.  • Do not use the following reserved names for the name of a file:  CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these names followed immediately by an extension; for example, NUL.txt is not recommended.
  • 11. Rename file or folder  As with other file managers, you can use Files to change the name of a file or folder.  To rename a file or folder:  1. Right-click on the item and select Rename, or select the file and press F2.  2. Type the new name and press Enter or click Rename.  You can also rename a file from the properties window.  When you rename a file, only the first part of the name of the file is selected, not the file extension (the part after the last .). The extension normally denotes what type of file it is (for example, file.pdf is a PDF document), and you usually do not want to change that. If you need to change the extension as well, select the entire file name and change it.
  • 12. Rename file or folder
  • 13. Common problem of naming  The file name is already in use  You cannot have two files or folders with the same name in the same folder. If you try to rename a file to a name that already exists in the folder you are working in, the file manager will not allow it.  File and folder names are case sensitive, so the file name catla.txt is not the same as catla.txt. Using different file names like this is allowed, though it is not recommended.  The file name is too long  On some file systems, file names can have no more than 255 characters in their names. This 255 character limit includes both the file name and the path to the file (for example, /home/wanda/Documents/work/fims – thesis report /…), so you should avoid long file and folder names where possible.
  • 14. Problem  The file name is already in use • The file name is too long max 255 characters
  • 15. File extensions Word processor and text file formats by file extension • .doc and .docx - Microsoft Word file • .pdf - PDF file Presentation file formats by file extension .ppt - PowerPoint presentation • .pptx - PowerPoint Open XML presentation Data file extensions .dat - Data file Font file extensions .fnt - Windows font file .otf - Open type font file Image file formats by file extension .jpeg or .jpg - JPEG image .png - PNG image Video file formats by file extension .mp4 - MPEG4 video file
  • 16.  Icon view  To sort files in a different order, click the view options button in the toolbar and choose By Name, By Size, By Type, By Modification Date, or By Access Date.  As an example, if you select By Name, the files will be sorted by their names, in alphabetical order. See Ways of sorting files for other options.  You can sort in the reverse order by selecting Reversed Order from the menu.  List view  To sort files in a different order, click one of the column headings in the file manager. For example, click Type to sort by file type. Click the column heading again to sort in the reverse order.  Name: Sorts alphabetically by the name of the file.  Size: Sorts by the size of the file (how much disk space it takes up). Sorts from smallest to largest by default.  Type: Sorts alphabetically by the file type. Files of the same type are grouped together, then sorted by name.  Last Modified: Sorts by the date and time that a file was last changed. Sorts from oldest to newest by default.
  • 17. Icon views • What kind of folder do you want? Optimize this folder for general item , picture ,music video & Documents  You can change the folder icon.  If you change the icon, it will no longer show a preview of the folder’s contents.
  • 18. File copying • creation of a new file • content as an existing file  Computer operating systems include file copying methods to users, with operating systems with graphical user interfaces (GUIs) often providing copy-and-paste or drag-and-drop methods of file copying.
  • 19. File deletion  File deletion is a way of removing a file from a computer's file system.
  • 20. File location Windows C:Program Files degonto document of study fishreproductionmale and female data • The disk path for the database and index files is set during the initial setup of the server node. • used for development purposes only.
  • 21. Viewing and sorting files and folder
  • 23.  Sort files and folders  You can sort files in different ways in a folder, for example by sorting them in order of date or file size. See Ways of sorting files below for a list of common ways to sort files. See Views preferences in Files for information on how to change the default sort order. The way that you can sort files depends on the folder view that you are using. You can change the current view using the list or icon buttons in the toolbar.
  • 25. Keep file safe  Keep It Locked  Create a Secure Password  Back up file
  • 26.  Keep It Locked  Although this might seem obvious, many people think since they live in a thief has trouble getting into your house, they may move on to an easier target with unlocked doors, so locking the door of the room where you store the file when not in use could prevent unexpected loss from a formerly trusted acquaintance.  i.e., Such as fish data  Create a Secure Password  Make it difficult for a thief to discover your password by being creative.  Figure out something you will easily remember but that doesn't contain obvious words or dates, such as family or pet names and birthdays or addresses.  Make sure it is at least eight characters or longer and uses a combination of upper and lowercase letters, numbers, and special characters (for example, !@#$%).
  • 27.  Back up file  When computer files contain information that is extremely important, a back-up process is used to protect against disasters that might destroy the files. Backing up files simply means making copies of the files in a separate location so that they can be restored if something happens to the computer, or if they are deleted accidentally.  The fish of bangladash-SIS-SRS backup  The Fish-red list-exoticfish backup  -method automatically makes three back-ups; the grandfather file is the oldest copy of the file and the son is the current copy.
