DTR file format details:

A file format defines how the data in the file is structured. The file format can be deduced from the file extension and the signature. 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. Our evaluation of the DTR files looks like this:

DTR is seldom used as a file extension and includes various formats for various programs. But the following two file formats are common:

25% of all DTR files start with the bytes ÝÝÝÝ, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The files are 4 MB to 70 MB in size, with a median of 23 MB. The file type is very recent. Several words can almost always be found in the files, e.g. FLEET.
6% of all DTR files have the same signature 202. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. The file size is in the range of 1 MB to 11 MB. The files contain the following words: Informational. Files like these have the following tags: traces and fabric.

The remaining 69% of all DTR files are different files with different signatures, often e.g. UTF-16 (LE). The category is runtime, probe, layout or reset. Drag & drop your file here to see the file format and a preview of your DTR file!
