imageiio.pe3, imaginfo.pe3, imageiio.pe4, and imaginfo.pe4 are the names of files that are auto-generated by some graphics applications from Ulead Systems. A pair of PE3 files, or of PE4 files, generally appears together. They presumably contain a thumbnail cache, and other indexing information.
Applications reported to create such files include iPhoto Plus, PhotoImpact, and Photo Explorer.
Identification
Some or all imageiio.pe3 files begin with ASCII "IIO1$".
Some or all imageiio.pe4 files begin with ASCII "IIO2H".
The imaginfo formats have no obvious signature. The version number such as three or four is stored in byte at offset 22.
Sample files
- Ulead PhotoImpact 3.0 - CD image from archive.org (PE3 files)
- Ulead Systems iPhotoPlus 4 (ULEAD) (1996) - CD image from archive.org (PE4 files)
