Hi Roshan,

Thank you for the information.

Unfortunately this is not the case in this scenario. It is possible to save other files(word) with the Original file name.

Further even after altering name to a simple one, this error keeps on coming.

I know we have measures against this, but I will ask anyway: could it be that the filename becomes to long? The document number as well as the other primary keys of the document revision is added together with the title, and the checkout path. In Windows this has a limitation of around 250 characters, depending on how deep the folder structure is that holds the checkout path.

Try to shorten the Title temporarily and/or change to a shorter and less deep checkout path and see if it helps.

Also, what's the path of the folder you select in the Copy File To... command?

Thank you for the reply.

It is possible to copy the name and manually save it in the same folder. Have also tried to enter a very short name just for the test – still getting the same error.

It seems this is not the issue.

Best Regards,

Enable the Debug Console and observe what happens there during the file operation and see if you can find clues.
