If Makemkv failed decrypting a UHD and created a dump file, which is the perferable way to send dump file, attchment or googledrive?

I used to send with attachment, but I worry that the mailing system might keep makemkv team from recieving the dump (cannot confirm though), will googledrive be a better option?

I'm using gmail btw.

I think either works, but most people send the dump as an email attachment.

For most dump files, especially larger UHD dump files, using Google Drive would be more suitable. You can generate a shared link after uploading the file and send it to the recipient, which can avoid the issue of attachment size restrictions.
