Comment 3 for bug 15495

Archive has been in the English language since at least 1603:

http://www.merriam-webster.com/dictionary/archive

Zip isn't even in the dictionary as referring to a collection:

http://www.merriam-webster.com/dictionary/zip

Zip is only knowledgeable to WinZip users of old. Noting that Windows XP built in support is labelled "Compressed (zipped) Folders". The litmus test should be whether a new computer user would understand the terminology "zip" or "archive", and quite clearly they will have no knowledge of the former and reasonable English education would be aware of the latter.

Transpose the title if you need further clarification: "ZIP Manager" doesn't mean anything if you don't know what a "zip" is.
