Extracting winrar unlimited file size till disk is full
I had exactly the same issue with the default file manager on Ubuntu 20.04 and a RAR file that was certainly not malicious.
I fixed it by using another RAR extractor, the one I used was xextractor :
sudo apt-get install xextractor rar unrar
Once installed you can simply open up xextractor from the application list, open up your archive and extract it ! I imagine it would work with other archive managers as well.
