It seems that firefox caches files something like here:
How would I search these directories for videos, like from youtube that are cached somewhere in there? I.e., like to find all mp4 files or all <insert-file-format> files.
I'm not aware of any features of the 'find' command that allow me to interrogate the properties of files. Anyone know how to do this? Oh, and the file names do not have convenient extensions they're all named some 8 digit hex code like 9F94Fd01 or BB999d01.
i.e. the files are not called thisisafile.jpg or hiimapngfile.png et cetera.
