MarsSeed [1] filed a deletion request for freefilesync [2]: Abandoned, broken Gtk2 package from 2020. License declaration is invalid: this is proprietary closed-source software, not GPL3. Source uses upstream's binary release. The pkgdesc is incorrect: this is not a backup utility, but a (locally mounted) folder comparison and synchronization GUI application. Not useful to keep in this defunct state, without a maintainer. There are several feature-equivalent, actively maintained alternatives. My preferred one for such use case is Krusader (split-view file manager). [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/freefilesync/
