What is a TM file?

TM files mostly belong to TeXmacs by Free Software Foundation. A TM file is a technical or scientific document created with TeXmacs structured text editor. The TM file is written in a mix of LaTeX macro language and XML. Although its contents are saved as plain text, graphical objects defined in a TM file are rendered as actual graphics in TeXmacs. Another type of TM file is a thematic mapper bitmap captured by the Landsat satellite. tecmail online email marketing application saves its configuration in a TM file.

How can I open a TM file?

You need a suitable software like TeXmacs to open a TM file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your TM file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a TM file directly in the browser:. Just drag the file onto this browser window and drop it.

TM format details:

If you know the file format, you can also find out how to open or edit 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. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the TM files:

TM is not a commonly used file extension and has no uniform or dominant file format. The following file formats are most commonly found in TM files:

15% of all TM files internally use the ZIP format, so multiple files are compressed and stored together in one TM file. 9 to 270 compressed files with names like manifest.json are common. A little tip: If you rename the file extension to .zip and then double-click, you will see the included files and images. TM files can be up to 57 MB in size, but are often around 69 KB - 11 MB. Certain words are almost always found in the files, such as JFIF. Examples of file names are project.tm.
7% of all TM files start with the bytes 09 0D 00 00 00 52 65 73 6F 75 72 63 65 54 79 70 crucial for this file format. These files contain neither text nor words, but only data. The file size is in the range of 47 MB to 400 MB. Certain words are almost always found in the files, such as ResourceType, mIsHiddenSubElement, mName, mNativeObjectPath, mResourceID, Library and TwinmotionToUnrealContent.

All other TM files (78%) have different formats, frequently e.g. GNU TeXmacs document and ResourceType.
