DiskZIP

Monetize every PC user worldwide with a software subscription for a service everyone is bound to need sooner or later.

Product usable already, with two caveats: (1) Needs a special driver to preserve kernel extended attributes, without which, some copy protected games fail to launch after disk compression. (2) Slowed down boot times on very large disks (large as in number of files stored, not size). A custom driver is planned to address both concerns.

Running out of disk space.
Losing data to malware and money to ransomware attacks.

Patented transparent disk compression technology which boots Windows directly from a compressed disk image. Unlike creating a ZIP file, nothing needs to be manually decompressed at any time - all apps work, all documents remain accessible. Just more free space, seemingly out of thin air.
As an added benefit, the compressed disk image is rendered impregnable to all known malware after Windows has finished booting. Attack surface on the target device is therefore effectively reduced to the changes made since the last compression pass.
