Why not the NTFS checkbox?
100 copies. 1× the space.

1× storedDuplicate data across your disk — even inside different files — is stored once, then compressed. NTFS can’t do this. Per-file compression can’t do this.

DiskZIP Offline
The more loaded your PC, the more space you get back. Installed Microsoft Office? Expect to recover about half the space it took — and the same for every other app and game on your disk!
Security
Impregnable to ransomware.
Ransomware can’t touch it. Your compressed image cannot be encrypted — recovery is one built-in System Refresh — the same feature that rescues you from a bad Windows Update.
- Malware cannot encrypt the compressed image
- Windows locks c:\diskzip.wim permanently
- Backup your whole PC by copying one file
- Move to a new PC by copying that same file — no Windows reinstall, ever
DiskZIP is not a compression tool.
Windows cannot protect itself from malware, bad updates, broken drivers, or accidental changes. DiskZIP is Windows protection, archiving, cloning, and cleanup in one — an end-to-end Windows lifecycle management solution. The hundreds of gigabytes of free space are simply the happy byproduct of the process!
