Hello Jose,
in default configuration DW Import only keeps Documents which were processed with warnings or with an error.
some settings for that can be changed in C:\Program Files (x86)\DocuWare\Desktop\DocuWare.DesktopService.exe.config
changes here might require a restart of the DocuWare Desktop Service.
the Key "RemoveTempFile" controls which files the Desktop Service keeps stored in the jobs folder. this affects both, Printer and Import. Probably also Scan.
Please keep in mind that tinkering with config files might break your Desktop Apps, I am not responsible for any possible misconfigurations.
