I deal with crypto and other financials. My pc runs Zorin16 (Ubuntu). I use Bleachbit and Sweeper intending to remove contents of swapfiles, caches, temprary files and all the sneaky places my confidential data might lurk.
As far as I can tell, neither software deals with swapfiles or all caches or all temporary files. As I don't know linux that well, I find it hard to locate these files to check or to include them in custom settings in bleachbit.
Any advice please? Any other software (that can be automatically installed on Zorin as I can't manually install or compile etc)?
