.GI Disk Image Files
GI files are disk images made by Windows CD and DVD burning apps. Since they are neither compressed or encrypted, File Juicer will be able to extract photos and other files from GI images
GI images with photos will work well with File Juicer. This is very similar to flash card recovery.
This will hardly work for video files as they are typically broken up in chunks. Especially for movies. However GI images smaller video clips will work, if they are in .mov or .mp4 format.
