Amazon.com Iomega Zip disks, with 100 MB capacity, make some applications possible that otherwise we would still be without. This 10-pack of 100 MB disks can be used with Quik Sync from Iomega. Quik Sync, which is a free download from Iomega, creates a Quik Sync Zip disk. Once you have created a Quik Sync Zip disk, files that you designate on your hard drive are automatically backed up to your Zip disk every time you make a change. You don't have to do anything more than install the software. Quik Sync won't interrupt anything that you're doing, since it does it all in the background. The software can even keep every version of your files, keeping a running version history of your work. From the Manufacturer Not only is Iomega known for their great storage devices, but they are equally known for their durable media products that help you increase your storage capacity. These disks work with Iomega Zip drives and store up to 100 MB of data per disk. Each disk comes with a five-year limited warranty. All Zip disks are pre-formatted, protected by a rigid plastic shell, and offer shirt-pocket convenience. Zip disks are durable and can easily shrug off the bangs, bumps and scratches that can ruin CD-R and CD-RW discs. And, because Zip disks are inherently rewritable, users don't have to stock one type of disk for write-once operations and another type for rewritable operations. The same Zip disk does it all with superior rewritable performance and durability.
