Files with the .002 file extension are associated with a number of file archiving and compression utilities. These programs can take one large file or a volume of files and will archive the files and compress them into a single archive folder. The resulting single archive file can be broken down into multiple volumes in order to make the archive size more manageable.
When an archive is split into separate volumes, each volume of the archive is assigned its own extension in numerical order. The .002 file extension is usually assigned to the second volume of the split file archive. In order to extract the files that are contained in the .002 file, you will need all of the volumes of the multi-volume archive.
