For the last year or so my InDesign crashes when I 'save as' to Google Drive. It happens 9 out of 10 times and is very frustrating.
Any help with this would be massively appreciated!
InDesign will want to save a temp file called .idlk to the folder which is hidden. And this is usually the culprit compared to other apps that don't have this function, as far as I know.
The .idlk file is used to help with recovery of crashed documents.
If you are having issues saving to the Drive then perhaps try adjusting your sync options or turning off the sync function to see if it improves.
If so - it's an issue with how Drive is syncing.
I don't use Google drive but it comes up on the forums a bit.
Have you disabled all smart sync features? If not, that's the first thing I'd try.
