.mxl (compressed MusicXml) file import problem

There is a problem with my dorico. I am trying to upload music scores to MuseScore .When I export a music score from Notion, then the file name says .musicxml, but when I export a file from dorico, it says .mxl.

I try opening that .mxl file, but it says error opening file and I can’t edit that score.
I really need some help.

Welcome @DeepBlue

mxl is just a compressed version of musicxml. MuseScore will usually read them both.

If you want to export uncompressed musicxml from Dorico, just select that option at the top of the export dialog.

MuseScore will usually tell you details of the ‘errors’, but also allow you to ignore them.

If you want to upload a failing Dorico export here (put it inside a zip file) someone will probably be able to help.
