c++ - Why should files be mounted in Linux -

I found an old library, which has some head-to-end data with files on floppy \ cd (transferring files on the network path) Reshuffles There is a thread in this library that checks every second that the file (for example floppy diskettes \ CD disc) is mounted.

Why? What action can be taken on mounted files only ?

Thank you very much.

To access the file in any way - Read, Write, Execute, Delete - You Must be able to specify your location. The location of a file is always its position in the directory tree, where Unix has a single directory tree that starts at a root.

Unless your file is on the device (and hence its own sub directory directory) "main" directory is in the tree, it is not accessible.
