Question

Is it safe to remove the local FlexiCapture 12 temporary files from %localappdata%\ABBYY\FlexiCapture\12.0\LocalDocumentStorage?

Answer

You can delete these files without any consequences. You can clean this folder manually if it uses too much disk space or you could create a scheduled windows task to clean up the folder.
