SortFolders() Token throws an invalid operation error

Question

Hello,
I have a big trouble with the SortFolder() token which simply isn't recognized by the GroupwiseCommander.
I just want to alphabetically sort a folder's subfolders and the Object API doesn't give me any way to do it, as far as I've seen.
The problem I encounter does not seem to come from the arguments I pass to the SortFolder() token, the token itself seems to be unknown to Groupwise.
I'm actually sorting the folders manually by re-creating then in inverse order, but this temporary solution is painful, not elegant at all and randomly throws access errors if I go too fast.
As described in the documentation, this method can take one parameter which is the folder name. I'm also asking myself how it cannot be ambiguous, for example if I have a Cabinet/FolderToSort folder and a Mailbox/FolderToSort folder.
Am I supposed to pass it a complete path? the folder's ID?
Forgive me if I'm missing something obvious or trivial!
I'm using Groupwise 8.0.2, on a 32 bits Windows XP (don't blame me), and trying to automate from a .NET environment.
Many thanks in advance.

Directory name, as any other object name (unless enclosed in double quotes) is stored in data dictionary in upper case. Therefore you must type it in upper case when providing directory name as literal. Change:
in_file :=UTL_FILE.FOPEN('Myextdir','abc.txt','r');
in_file :=UTL_FILE.FOPEN('Mylocaldir','abc.txt','r');to
in_file :=UTL_FILE.FOPEN('MYEXTDIR','abc.txt','r');
in_file :=UTL_FILE.FOPEN('MYLOCALDIR','abc.txt','r');Also, keep in mind UTL_FILE works with database server side files, not with client side files, so if directory is on the client in still will not work.
