Previewed files are not deleted

[Misaki]

It seems like this could be related to Bug #137308, where a user complained that previewed files were being deleted.

file-roller, also known as Archive Manager, doesn't delete files that are previewed without extracting them to a known location first. These previews are stored in ~/.cache/.fr-<random string>.

I believe the /tmp directory is cleared each time the system is restarted, but maybe the preview files aren't stored there for security reasons.

eog seems to not store references to a file maybe by design; sometimes when you change a file on disk, eog will reload the file, but it doesn't always do so. So maybe can't rely on other applications that have the file 'open' to actually have a reference to the index node or whatever, and users will expect the preview not to be deleted immediately.

Currently, it seems like some, and maybe all preview files are retained indefinitely, unless manually deleted. If a file is previewed more than once, multiple copies are created. Over time this can add up to a considerable amount of disk space.

Thanks, that seems known upstream https://bugzilla.gnome.org/show_bug.cgi?id=732073

file-roller is supposed to clean behind when closing but I guess there are case where it hits bugs and that's not done...

I just tested this with Bionic and it seems to be fixed. Previewed files ~/.cache/.fr-<random string> no longer exist after closing file-roller.
