If you're running OS/2, you've probably discovered how much disk space your powerful new operating system demands.

Not to worry. With Stacker for OS/2 & DOS, you can quickly and safely double the capacity of your hard disk to take full advantage of OS/2's power.

Using Stac Electronics' patented, award winning Stacker LZS technology, Stacker instantly and transparently compresses all your data, "stacking'" it more efficiently so you have more room for your applications.

After all, what's the point of running such a powerful operating system if you have no room to use it?

Everything You'll Ever Need to Know About Stacker for OS/2 & DOS

How does Stacker work?
Stacker increases capacity two ways - by storing data more efficiently than OS/2 or DOS alone, and by replacing repetitive data with tokens that point to the same data that is already stored.
Does Stacker support my OS/2 Extended Attributes?
Yes. All your extended attributes will be preserved when you stack and unstack a drive.
Does Stacker work with Windows?
Yes. Stacker is compatible with Windows and all Windows applications. It transparently compresses Windows and Windows data files just like it does DOS files.
Will Stacker work whether I use Boot Manager or Dual Boot?
Yes. Stacker supports all setup configurations for OS/2 and DOS together on the same drive or on separate drives.
Will I be able to access my existing Stacker drives under OS/2?
Yes. You can easily use any existing stacked drives that contain DOS and Windows information. Also, because DOS drivers are included in Stacker for OS/2 & DOS, stacked OS/2 drives can automatically be seen under DOS.
What if I don't even have enough room to install OS/2?
Just install Stacker before you install OS/2. Stacker compresses OS/2 at the same time you're installing it.
What file system does Stacker support?
Stacker supports the File Allocation Table (FAT) file system. FAT is the file system common to both DOS and OS/2. This means you'll be able to access all your stacked data whether you booted under OS/2 or DOS.
What changes will I see in my files?
Stacker automatically compresses files written to a disk so they take up less space. Accessing your files remains the same. Only now your disk has twice the capacity. And, you can install new programs just as you did before you stacked your drive.
Will my system slow down?
In most cases, you won't notice any slowdown in your system. The time required to decompress your data is offset by the reduced amount of data that must be moved from your disk. You may even see performance improvements on some disks and for some programs.
