Timestamp Zip Filenames – Mac Kung Fu, 2nd Edition

Tip 41Timestamp Zip Filenames

This is one of those tips a handful of people will find useful but is worth sharing nonetheless. Those who use OS X on server computers might find it particularly useful.

The following command will cause any new archives (zip files) you create to automatically have the 24-hour time appended to the filename. For example, creating an archive from the folder Pictures at 2:13 p.m. will result in an archive with the filename Pictures 14.13.27.zip (with the last two digits representing the second count).

To activate this feature, open a Terminal window (open Finder, select the Applications list, and then in the list of applications double-click Terminal within the Utilities folder), and type the following:

defaults write com.apple.finder ArchiveTimestamp -bool TRUE;killall Finder

To deactivate it at a future date, type the following into a Terminal window:

defaults delete com.apple.finder ArchiveTimestamp;killall Finder
