Summary
When scanning documents, Laserfiche Scanning will create temporary files in your Windows user temporary folder. After sending your documents to your Laserfiche repository, Laserfiche Scanning automatically deletes these temporary files. However, when you use Basic Scanning, it may not fully remove all the temporary files created in the temporary folder.
Resolution
There is a hotfix available for Laserfiche Scanning 7.2.1. The fix is an updated version of LFSOutputProcess.dll (version 7.2.1.1).
To update Laserfiche Scanning 7.2.1
regsvr32 "C:\Program Files\Common Files\Laserfiche\Batch Processor\LFSOOutputProcess\LFSOutputProcess.dll"
