UNA File

A file with the .UNA extension is a file known as SIMS Unauthorized Data. It belongs to the Misc Files category. This format is associated with Capita Business Services Ltd..

The reliable way to open a .UNA 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 .UNA 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.
