I need to send a seller various Excel and PDFs, yet I get an error message stating that it is an “illegal file format”. What gives???
I’ve never sent a file as is (pdf, doc, xls, txt), so I’m not sure this will help. However any files I send are in a Zip file and I’ve never had one issue.
Think you should try to change the file name.
Be sure the file names don’t have spaces or illegal characters.
just upload to dropbox or google drive…
