About DAT files

The .DAT extension is the ultimate "mystery box" of file formats, representing a generic data container that can hold anything from video streams to system configurations. The most frequent and frustrating use case for general users is the winmail.dat file - a proprietary Microsoft Outlook format (TNEF) that encapsulates valid attachments (like PDF invoices or DOCX contracts) but renders them inaccessible to non-Outlook users (e.g., on Gmail or Apple Mail). Users effectively get a locked box instead of their expected document. Beyond email, older Video CDs (VCD) store MPEG-1 video in .DAT files, which modern players often fail to recognize. Games like Minecraft and SimCity 4 also use this extension for binary assets and level data, which are proprietary and generally uneditable.

To solve this, the file content must be identified and converted. For winmail.dat files, the solution is to extract the trapped PDF, JPG, or DOCX files so they can be viewed normally. For VCD video files, converting to MP4 ensures playback on modern smartphones and TVs. For generic data (sometimes just a renamed PDF or ZIP), analyzing the file header allows you to restore the correct extension and open it with standard tools.

Use Convert.Guru to open and convert your DAT file.

Users also converted UNKNOWN, VCD, RTON, TNEF, TXT, DAT_OLD, ZIP, BIN, DTA, PDF, FP10, ATT and JPG files.



The DAT Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DAT converter.
