Can I move my configuration from one PC to another?
Yes. First install QAP on the new PC and copy/replace the newly created quickaccesspopup.ini file with the one copied from your previous PC. The quickaccesspopup.ini file can be found in the QAP working directory.
All your favorites, hotkeys and preferences from the Options will be preserved. Of course, only favorite folders, documents or applications with the same location on the new PC or having portable locations will work. Also, most Special folders favorites will work as-is on the new PC. For Special folder favorites that do not work, delete them and add them again using the Add Favorite button.
However, if you are moving from a portable installation to an "easy setup" installation (or vice-versa), you should read this: Can I change from/to "easy setup" and "portable installation" without loosing my favorites?
