DT5 format details:

If you can determine the file format, the associated program can also be determined. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the DT5 files is as follows:

DT5 is rarely used as a file extension and is used by a few programs, each with its own file format. But the following two file formats are common:

50% of all DT5 files start with the bytes 00 00 00 00, which are crucial for this file format. They consist of illegible, cryptic characters. Most of these files are 4 KB to 230 KB in size. The file type was used 20 years ago. The files contain the following words: BROTHER. The file name BKPERSON.DT5 or Bklocate.dt5 is typical for these files. Such DT5 files store data about bkmarr, bkmail and bksource.
20% of all DT5 files start with the magic bytes v5|;dWklM0, which are always the first bytes of this file format. If you open these files in a text editor, you can view and read the content yourself. DT5 files are between 790 bytes and 26 KB in size. The following keywords are characteristic: dWklM, QyUzQWN, FTZXNzaW, uSWQlN and JTNBMzYwJTdDJTNBc. These files are attributed to exam, linked and gmail.

All other DT5 files (30%) have no consistent format. If you want to find out which format your DT5 file belongs to, just click on the button "Choose your .dt5 file to analyze".
