Good eyes. [Vendor] is a folder. The backslash in the filename field, a result of an index export from a scanning app.
Example
Vendor = Jump
Filename = \889765-060426.PDF
K:\matl certs\jump\889765-060426.PDF
But upon further investigation I see the filename in the DB does not match the actual filename. Hmmm seems the index app has added spaces around the - in the file name. So perhaps this is a case of checking my work.
