Validation error in non-existent file

I get the following error when attempting to publish a project in UiPath 2018.1.3:

Project cannot be published. ~Save file has validation errors.

I have checked all my workflows for validation errors and there aren’t any (I also don’t have a file called ~Save). I see from reading other posts that this could be due to a file path being too long? In this case, what is the max length for a file path and why is this not documented? Any help would be greatly appreciated!

I managed to solve this one myself. In case anyone else comes across a similar error, the cause of this was there was a hidden .xaml file called ~Save. I’m not sure how this got here so if anyone could give me an insight I’d be very interested to hear.
