You have been asked to maintain a legacy application called 'File Drop' that was designed for BSD Unix and has to be ported to Ubuntu Linux. The target OS must be Linux to stay with a free OS (your company doesn't have that much money yet). The application monitors two FTP folders. One folder is used by multiple (internal) departments to drop files listing their job openings (JobsFolder). The other folder is used by an external recruiting company to deposit completed applications from prospective job seekers (ApplicationsFolder). The HR department (also internal) relies on the FileDrop application to notify the recruiters each time a new job opening files is dropped into the JobsFolder, and to notify the HR department each time a new Application is dropped into the ApplicationsFolder. In each case, an email is sent to the appropriate person via email. You need to understand the current system, maintain the general architecture 'as-is', but port it to Linux. You need to ensure the system only allows the proper (approved) people to access each folder. You are a software engineer for a software development firm who has been contracted to build the system..
