Text DAT Files vs Binary DAT Files: What Is the Difference?
DAT files usually fall into two broad groups when you inspect their contents: text DAT files and binary DAT files. The difference matters because each type needs a different way of viewing and understanding the data.
A text DAT file may contain words, numbers, settings, logs, or rows of structured data that you can read directly. A binary DAT file stores bytes in a form designed mainly for software. When opened in a normal text editor, binary data often appears as strange characters or unreadable symbols.
.dat extension because DAT is a generic data-file extension rather than one universal file format.
Text DAT Files and Binary DAT Files at a Glance
Text DAT File
Designed so some or all of the data can be represented as text characters.
- Often readable in a text editor
- May contain settings or logs
- Can contain CSV-style records
- May use commas, tabs, pipes, or semicolons
- Usually searchable as normal text
Binary DAT File
Stores data as bytes that may need software or a defined file structure to interpret correctly.
- Often unreadable in Notepad
- May contain application records
- Can store game resources or media
- Useful to inspect in hexadecimal
- May require the original program
The key point is that the filename alone cannot tell you which type you have. As explained in our guide to whether all DAT files use the same format, different applications can create completely different DAT structures.
What Is a Text DAT File?
A text DAT file stores information using character encodings that text software can interpret. If you open one in a normal editor, much of the content should look like recognizable letters, numbers, punctuation, and spaces.
For example, a program might store preferences like this:
language=en theme=dark autosave=true max_results=50 username=alex
The values are directly readable and could be inspected with a text editor or DAT viewer.
id|customer|total 201|Aisha|35.90 202|Daniel|72.50 203|Mina|18.00 204|Omar|96.40
This file is also text, but its repeating pipe separators make it suitable for a table view.
Text DAT files are not required to follow one particular structure. Some contain simple lines. Others resemble CSV or TSV files. A program can create its own text layout and still save it with a .dat extension.
What Is a Binary DAT File?
A binary DAT file stores information as byte values rather than as a sequence intended to be read directly by a person.
All files are made of bytes at the lowest level. The useful distinction is how those bytes are organized. In a text file, many bytes map directly to characters. In a binary file, a byte or group of bytes may represent an integer, timestamp, image value, index, compressed block, application flag, or something else entirely.
00000000 44 41 54 01 00 10 00 00 00000008 A9 21 F4 00 71 09 8B 33 00000010 52 45 43 00 01 A7 39 F2 00000018 00 00 12 4C B3 19 02 88
A hex view shows each raw byte even when the file is not readable as normal text.
89 AF 02 11 00 80 39 2B 54 45 58 54 55 52 45 00 B3 88 40 FF 10 21 00 09 player_skin_01.....
Binary DAT files can still contain small readable strings mixed with binary bytes.
A general viewer may reveal those readable strings, but interpreting every binary field may require documentation or the application that created the file.
Text vs Binary DAT Files: Main Differences
| Feature | Text DAT file | Binary DAT file |
|---|---|---|
| Readable in a basic text editor | Usually | Usually not |
| Can contain normal words | Yes | Sometimes, mixed with binary data |
| Can use delimiters | Yes | Not in the same plain-text sense |
| Good for spreadsheet import | Sometimes | Usually no |
| Useful in a hex viewer | Possible, but often unnecessary | Yes |
| Easy to search for words | Usually | Only for embedded text strings |
| May require original software | Sometimes | Often |
