What is the B4U file format?
A file with the .B4U extension is a file known as Visual ReadMe. This format is associated with Tuukka Salonen.
The reliable way to open a .B4U 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 .B4U 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.
