Файл GI

.gi is a disc image file format produced by the Prassi Global Image burning suite, later marketed as RecordNow under Veritas, Sonic Solutions, and Roxio. It stores a sector-by-sector binary copy of a CD or DVD, with a small proprietary header preceding the raw sector data; the payload usually embeds an ISO 9660 or UDF filesystem. .gi files can be mounted as virtual disks and accessed like normal discs. They can also be used to create optical data discs. The format is associated primarily with the Roxio Creator/RecordNow toolchain but is supported by several disc-image and virtual drive tools. The .gi standard is proprietary and not publicly documented, and the software that originated it has long been discontinued - making it a niche, seldom-used format today.

Creating a disc image from a copyrighted disc is not considered a breach of copyright or license agreement, provided that the user has access to the original media disc. Creating virtual disks allows the user to access data that would otherwise require a CD/DVD drive attached to the computer, and is a common solution for extending the lifetime of an optical disc or speeding up software installation. Because RecordNow and PrimoDVD are no longer actively developed, working with an existing .gi file typically means burning it back to disc with a compatible tool such as ImgBurn or IsoBuster, or attempting to treat it as a raw sector image - similar to a BIN file - and extracting its contents.
