Hi all,

Thanks for your input.
What we did was the following:
1. We copied all the files to a different directory with posix.
2. Deleted the posix directory
3. Deleted the mpe group
4. Created the original directory in posix
5. Copied all the files to that directory

The negative result is that the files are not visible with listf command.
But they are visible with listfile command.
The directory is used for ftp and we don't have issues not having the files
as MPE files.

Kind regards,
