Excluding specific file


I’m backing up my OneDrive folder using Duplicati.
I get the following warning message:

2022-10-27 13:00:26 +02 - [Warning-Duplicati.Library.Main.Operation.Backup.FileBlockProcessor.FileEntry-PathProcessingFailed]: Failed to process path: C:\Users\MyUsername\OneDrive - CompanyName\Filename

The filename is something like this: “.123a123456-a123-1a12-1a1a-123456a1a707a”

Maybe Duplicati can’t reach the file because it’s being used. Regardless I’m not interested in backing up this specific file so I’d like to exclude it.

How do I exclude this specific file on the GUI?
Or how would I change this through the command line?

Edit: I’m running version “”

Hi GasClown,

Welcome to the forum!

One method of doing this, is to add this file to the exclusion list in the “Source Data” (3) page of Editing your configuration in the GUI.

That screen looks like this:

You can see one of my folder filters at the bottom of the screenshot (“C:\WINDOWS.~Q”). You’ll need to click “Filters v” (the “v” is a down arrow), then click “Add filter”. From the drop down that will appear (where you see “Exclude folder” in mine) select “Exclude file” then give the full path to the file. You can then add more filters by clicking “Add filter” again.

Good luck!
