What is a SEF file?

A .SEF file can belong to several different software applications. Because multiple developers use the .SEF extension, these files often contain completely different types of data. Common uses include encrypted containers from Steganos Privacy Suite or SoftCamp, Electronic Data Interchange (EDI) Standard Exchange Formats used by Stylus Studio or TIBCO, and sports meet entry data files for Hy-Tek MEET MANAGER. Other systems use the format for structured event logging, trading strategies in MultiCharts, or even as an Encryptafile Signature File developed by XenoSystems.

How to open SEF files?

Because a .SEF file could be an encrypted volume, an XML-based video surveillance export, or a compressed ZIP log, you first need to identify the exact format. If it is an encrypted file, you must use the original security software, such as Steganos or Spirion, and possess the correct password. If it is an EDI document or a plain text log file, standard code editors or specialized developer tools can read the data.
