Sorry to report that because IOMEGA was bought out, they stopped supporting their file extensions of .IAB
What does this mean, and how can you open the file to restore?
The ONLY way to do open and view the files within the .IAB file is to use the SAME IOMEGA utility that MADE the .iab files.
WHomever sent you the IAB file, might know who created the file, and might have access to the machine that creted the file, which would also have the utility (IOMEGA AUTO BACKUP UTILITY)
Basically, you need the Utility to open and view.....the convertors don't work....the utility is no lnger being offered for download from IOMEGA o Lenovo.
The last option for folks who need this resolved, are instructed to contact LenovoEMC directly, to explain.
Lenovo is taking these requests one by one, and handling them on a case by case basis.
Contact Lenovo, as there are no resources available to the general public to solve this.
