Instant Folders - Notes to users of previous versions
Version 2.2
The internal mechanisms of Instant Folders have changed to take advantage of the Alias Manager. Therefore, the structure of Instant Folders' preferences files changed.
If you used a very old version of IF (prior to 2.0), trash the old preferences file before running version 2.2!!!
You can find that file inside the "Preferences" folder inside the "System Folder".
If you've been using IF 2.0 you don't need to do it.
You will have to rebuild your list of folders. I'm sorry, but it was necessary. From now on, however, the file structure is likely to stay the same since now has all the flexibility I needed.
