Files show up with garbage titles when viewed on windows (eg, samba, NFS)

[TheDauthi]

This is just how colons are handled when attempting to show them on a windows file system. They show up with what appears to be a tmpfile name (TWWH39~Y, as an example), since colons are invalid in windows file names. It's making up an 8.3 name (or just 8 for a directory name).

Sonarr has an option that converts them into ' - ' for this reason.
