Dolet 7 can do it:Does anyone know the FinaleScript way to do this to a batch of files?
Full batch translation
Dolet 7 lets you translate an entire folder of MusicXML files into Finale files, or an entire folder of Finale files into MusicXML files. If you have a lot of files to transfer, this is an enormous time saver.
Works with more versions of Finale
Dolet 7 works with Finale 2011 to 2014.5 on Windows and Macs.
Open Finale without opening a file > go to Plug-ins > Miscellaneous (at least that's where I have it) > MusicXML > Translate Folder to MusicXML > Browse for Folder > choose which one you want to translate > go
The newly created XML files are all placed into that same folder.
Before starting, in MusicXML Preferences one can choose compressed or uncompressed XML versions.
