tif, tiff, pdf. But once they are in QF they will obviously be imported into LF as TIF.

What version of Quick Fields are you using? If Quick Fields 10, does this message occur in Quick Fields or Quick Fields Scanning or both?

Can you post the full error message?  If you press F12 to open the application errors pane, you can copy the details of the error message.

QF 10. message occurs only when I try to store the documents. The error message text that I typed in the subject field is the full error message. That is why it is so generic. No code, nothing. It will not store any document. The only thing I have changed is added a volume to the system. I have checked the security on the volume and it is identical to a few jobs that I already have running without issues.

It's not quite the same though. Could you try opening the Application Errors pane and checking if there's a more detailed message after storing documents failed?

Is there a folder with the same name as the document in the folder you're trying to send this document to?

No. The folder is empty.

But.... thanks for putting me on the right track though, because once I deleted the destination folder and re-added it (using the same name) it works. So either way thanks so much for your help!  There must have been something in the name that was not visible or was corrupt.
