Comparisons of EXTs File system Maximum filename length Allowable characters in directory entries Maximum pathname length Maximum file size Maximum volume size ext2 255 bytes Any byte except NULL and / No limit defined 16 GB to 2 TB 2 TB to 32 TB ext3 255 bytes Any byte except NULL and / No limit defined 16 GB to 2 TB 2 TB to 32 TB ext4 256 bytes Any byte except NULL and / No limit defined 16 GB to 16 TB 1 EB (but user tools limited to 16 TB)

12. File structure Root Directory:/ /bin /boot /dev /etc /home /lib /media /mnt /tmp /sys /usr /var

13. Root Directory Begins filesystem structure /usr Holds subdirectories that support user Administrative application libraries /media Used for mount points Mount CD-Rom, DVD,floppy

14. /mnt Used for mount points Mount filesystem (windows partition) /home Hold home directories Like user account /var Holds files and directories that frequently change Like web server files, log files, printer spool file
