If you’re thinking about using Deep Freeze, you’ve probably asked this question. It’s crucial to understand before installing it.
The short answer: No, Deep Freeze does not save files or changes made to a Frozen drive after a reboot. That’s the whole point: it restores the computer to its original, configured state every time it restarts.
Why changes don’t stick
Deep Freeze works by 'freezing' the computer’s configuration. Any changes you make while the machine is running - whether that’s installing new software, changing settings, or saving files to the Frozen drive - will be completely erased when you reboot. This protects against unwanted changes, malware, and misconfigurations.
How to keep files permanently
If you need to save data or updates, you have several options:
-
Use a Thawed drive or partition: files saved here won’t be erased after reboot.
-
Data Igloo: this nifty Faronics tool lets you automatically redirect user profiles, folders, and data to a Thawed location so they survive a reboot without changing the Frozen system.
-
Cloud Sync in Faronics Cloud: keep critical files backed up to OneDrive, Google Drive or Dropbox in real time, ensuring they’re safe and accessible even after a restart.
-
Temporarily Thaw the computer: IT admins can 'unfreeze' a workstation to make updates or install software, then refreeze it once changes are complete.
Why IT teams like it this way
For shared computers in schools, libraries, and training centres, the fact that nothing sticks means every user gets a fresh, reliable machine every time. There’s no clutter, no malware left behind, and no accidental settings changes to undo, while tools like Data Igloo and Cloud Sync make it easy to keep essential data safe.
Final takeaway
If you need files to survive a reboot, store them on a Thawed drive, in the cloud, or use Data Igloo or Cloud Sync to automate the process. Deep Freeze’s power lies in keeping your systems exactly as intended — clean, secure, and ready for the next user.
