Been awhile since I saw a thread like this and they’re always good for at least one or two things I’ve never heard of before. Bonus points if the software is open source and cross platform. Extra bonus points if you link to where we can see it/get it.
My contribution: Destiny which is an anonymous, P2P, E2EE file sharing app - its basically a GUI for a Magic Wormhole implementation. Works on Linux (tarball or appimage), Win, Mac, Android (inc f-droid) and iOS. Only downside is it’s not been updated for 2 years.
Windirstat
A windows app that shows you the space things are taking up on your computer so you can easily delete them. Usually helps me clear out a ton of space.
The same disk space visualisation, on Linux, can be shown with:
gdmap
(Available from your distro package-manager)
dua-cli is good for this.
I prefer WizTree. It’ll show you space usage, but you can also search for files, and it’s incredibly fast.
I’ll have to give it a try one day.
