.GCD File

The gcd file extension was in the past used for older disk image format created by Prassi burning software (like Prassi Global-CD), a program distributed with some professional CD/RW burners.

Prassi also licensed and later sold the product, so it is highly likely that programs with different name used the same file format. Such programs like Sony CD Extreme, Veritas My CD, My CD Pro, or Sonic RecordNow! were often bundled with various DVD/RW drives.

In 2001 Veritas acquired Prassi and the company is now defunct, the original software no longer sold or supported. However some 3rd party software still support GCD format.

DVD images created in Prassi software typically had gi file extension instead.

Files with gcd file extension can also be old disk images created with Prassi burning software. This file type is rather rare, but some programs still support it.

How to open:

Various 3rd party programs like ISOBuster, PowerISO or UltraISO support Prassi GCD format and its clones and are able to open and burn *.gcd files.

How to convert:

Typically, programs that can open and burn .gcd images, can also convert them to other formats, including common ISO format.
