Subject: Delete orphan files maintenance script
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=38a187b93ebe1069f105ccd7570b7bb6ab38fc50;p=quix0rs-gnu-social.git

Delete orphan files maintenance script

When deleting a profile it'll delete its notices and the coupling to
file entries, but not the file entries themselves (and thus not the
files). So if one to delete a person uploading offending images, then
the images are left behind and can be hotlinked. This will remove it.
