This is actually a good policy. However, sometimes it’s annoying to wait for a few hours before these files are being cleaned up. In particular, if we are sure these files are unused or orphaned, there is another module called Fancy File Delete, which solves this problem.
Fancy File Delete allows you to delete files straight away without having to wait.
However, great care must be taken when using this module, because it has a ‘force delete’ option. Use of this module should be restricted to experienced administrators.
