Apps · Offloading and restoring apps
What happens if my fast drive doesn't have enough space to offload an app?
Short answer: It won't start: you'll see that there isn't enough free space to complete it safely, and nothing changes. Make room on the drive and retry.
Storage Studio checks before it starts and won't begin an offload that can't finish safely. You'll see "There isn't enough free space to complete this safely, so nothing was changed."
Free up room on the fast drive — for example by removing offloaded apps you no longer need — then try again.
