The unlink is not about removing file, it's about removing a file name. That's the simple, usual case. However, it's perfectly fine for a file to have several names see the link function , in the same or different directories.

Only when all the names are removed, the body of file actually is freed. The body will not be deallocated will not free disk space as long as the process holds it open. In fact, there's a fancy way of resurrecting a file removed by a mistake but still held open by a process To delete all files of a particular extension, or infact, delete all with wildcard, a much simplar way is to use the glob function. Say I wanted to delete all jpgs I have been working on some little tryout where a backup file was created before modifying the main textfile.
