Hello, I just found user who has single folder (standard maildir format) that filled with over 8mil files and 800GB in the /tmp subdirectory of that folder:
Are they real files or hard links?
How would you distinguish a hard link from a “real file”?
ls -l will show the number of hard links to a file in the first column after the permissions (or it showed the number off files (including . and ..) inside a directory if it's a directory entry).

There are other ways, including the stat command.
