[Deprecated] I moved the extractions to a new device, and assigned it as the storage, but Oxygen keeps crashing when I add the "unsaved" extractions.
Create one folder, to hold your cases, in the same storage location - though this time, please transfer the files 5 cases at the time.
Once the initial 5 are copy/pasted - please start Oxygen Forensic so it can load the cases; Once loaded, you can then transfer another 5 cases into the folder.
