Notes

• API call implemented in OZ 5.0
• Several sub-directories are accepted (eg. :RAM.0/dir1/dir2/dir3 ) up to 205 characters
• Only accept explicit filenames (wildcard are not allowed)
• However, if a RAM device is not specified, it will automatically be included (the current) into the directory name.
• The buffer of the directory name must have space enough to get itself expanded with a device name (additional 6 bytes).
• The filename must be terminated by a control character, eg. null (0) or CR (13).:EPR.x files are deleted from the filesystem tree and marked as deleted in the filearea.
