In computing, a file system or filesystem (often abbreviated to FS or fs) governs file organization and access. A local file system is a capability of an operating system that services the applications running on the same computer. [1] [2] A distributed file system is a protocol that provides file access between networked computers.
A computer file is a resource for recording data on a computer storage device, primarily identified by its filename. Just as words can be written on paper, so too can data be written to a computer file. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet.

Therefore, caution has to be used when stating a “file was last accessed by user XXX” if there is only the “File Access” date in NTFS to work from.

Some operating systems restrict a user's access only to their home directory or project directory, thus isolating their activities from all other users.
