Mac OSWhat is the X3F file format?
A file with the .X3F extension is a file known as Sigma Camera RAW picture. It belongs to the Data Files category. This format is associated with SIGMA.
The reliable way to open a .X3F 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.
