Linking non-matching folders
PowerBook File Assistant lets you link folders that have different names and
contain different files.
1 Choose Preferences from the File Menu.
The following dialog box appears:
2 Click the checkbox to allow non-matching folder names.
3 Click OK.
Now you can link folders that have different names and contents. The first
time you synchronize a pair of non-matching folders, PowerBook File
Assistant copies all the files from one folder to the other, so that the folders
have identical contents.
