How toHow to

Software for validation and conformance checking:

• tiff: DPF Manager (http://dpfmanager.org/) NoteNote

  Using DPF Manager Lite gives an error: https://github.com/EasyinnovaSL/DPFManager/issues/493
  The workaround from the linked issue works. Thus, if it es e.g. installed in 'C:\Program Files\DPF Manager\app', from an command line (with java installed) just execute
  

  java -jar "C:\Program Files\DPF Manager\app\DPF Manager-jfx.jar" 
  

  How toHow to
  DPF Manager can be used to validate single files or whole folders. These are the steps to recursively check folders (with a screenshot):

  1. Start DPF Manager
  2. In the Files Check Tab click on Select and in the drop down either chose folder or tree view
  3. navigate to the folder you whish to check and select it
  4. Check the Box 'Recursive' right below the Folder input field
  5. Chose the 'Default' Tiff configuration for checking
  6. Start the check with a click on 'Full check'
  7. When the check is done the results can be viewed in the program (go to Reports tab) or can be found in the local user profile\DPF Manager\reports (click the folder icon in the Reports Tab)
