If the export path has a different drive letter/path than the "_workingpath":
export filename: D:\myaudio.xml
When saving an export file to a directory other than "_workingpath", the "_folderpath_rel" field contains the absolute path (e.g. "M:\path\to\folder").
If the drive letters are the same, i.e. :
export filename: C:\myaudio.xml
This is using version 2.43
Why isn't "folderpath_rel" relative to _workingpath in this case?
