"Error opening file" when trying to open MusicXML files on iPad

[DeepBlue]

Hello guys! There is a problem with my Dorico. I cannot open my 20 Music MXL files. I archived them on my iPad (I just basically stored them in a folder that I see everyday) then I tried to open them a few months later, this black screen with a white GUI with the error message “Error opening file” just appears.

I have a pretty decent Prelude that I want to edit, but I can’t. When is this big going to be fixed??

So, there is something wrong with your file and you expect us to look deep into our crystal gem and do some guessing?

No, seriously:
Please provide one of the files so the team can have a look at them

I fixed hehe… I just simply moved the files into the Dorico folder then it just mysteriously started working. Strange……
