Comment 67 for bug 15495

I do not think that we should simply use a particular term just because it is understood by users of a particular operating system: as has already been mentioned above, Windows and OSX use different terminologies anyway.

I prefer the idea of using our own expressive terminology, ideally something that a complete novice to computer systems in general might grasp intuitively. As such I would suggest using the terms "group" (or "bunch"?) and "compress" (or "squish"?) in a context-sensitive manner. For example, right clicking on a single file could offer the option to "Compress this file...", whilst right clicking on a selection of multiple files would offer something along the lines of "Group and/or compress these files..." (or "Bunch and squish these files..."?).
