What is the GAB file format?
A file with the .GAB extension is a file known as Dencom Global Address Book Export. It belongs to the Misc Files category. This format is associated with Dencom.
The reliable way to open a .GAB file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .GAB files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
