What is the R66 file format?
A file with the .R66 extension is a file known as RAR Compressed Files From A Multi-volume Archive. This format is associated with Eugene Roshal.
The reliable way to open a .R66 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 .R66 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.
