DriveSpace: Zero Downtime

Increase your disk storage in a single click, while Windows is still running - ideal to compress remote servers. DriveSpace 6 uses advanced LZX compression if you are running Windows 10, while fully supporting older Windows versions (including XP) with LZNT1 compression.

DoubleSpace: The Most Space

Runs directly from your PC boot menu, so you don't need to worry about creating a bootable USB device. DoubleSpace 2 layers WIMBoot and LZNT1 compression to bring you the absolute maximum in space savings, with other conveniences such as disk cloning as well.

Double Your Disk and Accelerate Disk Reads

Because modern CPUs are much faster than even the most advanced SSDs, even ultra-fast SSDs experience increased read speeds after compression. Compress your disk and increase your disk read speeds at the same time. Both DriveSpace 6 and DoubleSpace 2 provide one-click, safe, reversible disk compression, letting you use all your apps and data as if they were uncompressed. Compress a disk 200% to 1,000% faster than Windows's built-in tools, and create up to 300% more space.

Secure E-mail Compression, Attachment Preview

ZIPmagic's Outlook Add-In integrates with every version of Microsoft(R) Outlook(TM) to auto-magically compress your email attachments when you click the "Send" button. Toggle compression on/off with the single click of the mouse, choose a different compression format, and even tweak compression algorithm parameters right within Outlook. Encrypt your data with 256 bit AES secure encryption and protect your sensitive data from prying eyes.

ZIPmagic's Outlook Integration does not stop with just attachment compression. Up to 61 different types of archive formats may be previewed when received as email attachments in Outlook. Double-click any file inside an archive preview to open it!

Intelligent Software That Works For You

Does your archive management utility create two levels of subfolders when you choose the "Extract to Subfolders" option? ZIPmagic is smarter, creating a parent folder only when it determines the archive doesn't already contain all of its files inside a master folder. Do you need to ensure no compressed files are left behind after extracting? Choose the "Recursive Extract" option and watch ZIPmagic sift through all archives nested inside one another for you.
How to compress files

How to Compress Files to Get the Smallest Possible Size?

First, in Windows Explorer, highlight the files and folders you want to compress. Next, right-click this selection of files and choose the "Find Smallest Archive" menu item. ZIPmagic instantly benchmarks all available compression algorithms on this live data set!

You may not already know this, but each compression algorithm has its own strengths and weaknesses - there's no single "best" one for all possible files. Fortunately, you now have a single-click way to find out how to compress files for the smallest possible size, every time!
