@GETFOLDER[startdir[,title]] : Returns a folder selected from a tree view of available symbolic folders. If you don't specify a start folder, @GETFOLDER starts at My Computer or the equivalent symbolic folder in your Windows configuration.
The optional second argument sets the text to display above the tree view.
If startdir is quoted, the returned folder name will also be quoted (if necessary).
Examples:
echo %@getfolder[]
echo %@getfolder["c:\windows"]
Note: @GETFOLDER deals with folders. All directories are folders, but not all folders are directories. To select a directory, see @GETDIR.
