Unknown file extension list

Unknown or not yet specified and assigned file extensions.

This group contains all the unknown or otherwise not yet specified file formats. At the time of our research, we could not find any reliable internet source that would help us determine what kind of file type it is, what it's purpose is and in what kind of program can open or otherwise work with it. A lot of these 'file types' may also be common user mistypes or names of files that lack actual file suffix, which can confuse some users.

If you know some useful information about any of the file extension entries in this category, please send us a message on our forums, by clicking on 'submit extension' button at the top of page.
