DoubleSpace restarts your PC in a patent protected (U.S. 10,911,065), exclusive processing mode to transparently compress your disk as tightly as possible.

Unlike other kinds of compression products, after rebooting, you access all your files and apps compressed by DoubleSpace as if they were uncompressed!

DoubleSpace is guaranteed to create at least 5 GB of free disk space at its highest (MaxSpace) compression setting - this is how well the raw operating system files compress.

Ironically, the more apps and files you have installed - the more free disk space you will create!

Unlike other well-meaning but often inadvertently harmful disk cleanup tools, DoubleSpace creates all this free space for you without deleting a single file!

All your apps, data, and settings are 100% safe, because not a single file gets deleted or moved or hard-linked, ever.

DoubleSpace even lets you use an optional, external “Undo Disk” to guarantee 100% data integrity.

This “Undo Disk” protects you even in the event of an unexpected power outage, hard disk failure, or any other kind of unforeseen hardware/software defect, which would otherwise cause data loss.

DoubleSpace is also reversible - you may safely uncompress your disk at any time, if for any reason you’d like to go back to a PC with less disk space.

So just sit back, relax, and enjoy the maximum storage your disk can offer you only with DoubleSpace!
