Instead of using paid programs such as screen recorders and file extractors, you can instead look for open source alternatives to those. Open source programs are usually free to download, modify, and redistribute. To find those programs, just search on Google,
“Open source ... [Whatever kind of program it is]”
There are open source screen recorders, file extractors, game engines, video editors, photo editors, and many more.
VLC, Audacity, and OBS Studio are all amazing.
