FIX file format details:

To find out what program is needed to open FIX files, you need to determine the file format. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the FIX files looks like this:

The FIX file type has no uniform or dominant file format. But the following two file formats are common:

• 15% of all FIX files use the same file format, which can be identified by the letters "FILE-INDEX 3 "" at the beginning. The contents of these files are easily readable with a text editor. A typical file size is 470 bytes. The file type was developed 10 years ago and is still in use today.

Such FIX files store data about nondicom.
• 10% of all FIX files start with the bytes 01 00 00 00 crucial for this file format. They consist of illegible, cryptic characters. The average file size is 120 bytes with most files being between 25 bytes and 26 KB in size. Files like these are sometimes connected to area.

The remaining 75% of all FIX files are different files with different signatures, often, for example, Soubor and FIX.
