Pre-scanning Error xlf files

Dear community,

When trying to process xlf files we received the error message above. We have processed similar (identical?) xlf files for this customer before and never any trouble loading them in Studio.

Pre-Scanning failed to identify the file type, the following messages were generated:

Pre-Scanning error: Name cannot begin with the '>' character, hexadecimal value 0x3E Line 467, position 111.

Maybe the customer changed something in the structure of the files? They look the same.

Does anyone have an idea on how to solve this?

Regards,

Anthoinette
