Trouble Opening a .39 File? These Steps Will Help

Because .39 files can originate from various programs, they aren't universally openable with standard applications.

1. Identify the Source: If received from a collaborative project, it may be a 4COLLAB archive. If part of a split download, it suggests a multi-volume compressed archive.
2. Check the Header: Open the file in a hex editor to inspect its first bytes:
   • "PK" indicates a standard ZIP-based archive.
   • "Rar!" suggests a split RAR archive volume.
   • Unreadable binary data may point to proprietary 4COLLAB compression.
3. Use the Original Software: Opening the file usually requires the original program, such as 4COLLAB, WinRAR, or 7-Zip; if uncertain, ask the sender.
4. Use this Webpage: Drag and drop your .39 file into our viewer above to detect its format, extract readable metadata, and preview its contents.

39 file format details:

Every file has a defined file format, i.e. how the data is arranged in the file. 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 does not match the file format, double-clicking on the file will cause an error upon opening. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the 39 files:
