So here is my line that did not retturn an error, as i had still blobs folders of the decomissioned test sats left.
syntax sample
windows GUI, powershell, admin rights, node running, cd to folder where the storagenode.exe is. with
cd “C:\Program Files\Storj\Storage Node”
and:
.\storagenode.exe forget-satellite --force 12rfG3sh9NCWiX3ivPjq2HtdLmbqCrvHVEzJubnzFzosMuawymB 12tRQrMTWUWwzwGh18i7Fqs67kmdhH9t6aToeiwbo5mfS2rUmo --config-dir “C:\Program Files\Storj\Storage Node” --identity-dir “C:\Users\Mini\Documents\storj\Identity\storagenode”
After a day (i let the shell window open, just to be sure), the blob folders of the decommisioned sats were gone. Adapting the paths behind -dir may be sure neccesary.
