LMS file format:

To find out what program is needed to open LMS files, you need to determine the file format. The file format can be deduced from the file extension and the signature. 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. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the LMS files comes to the following conclusion:

The LMS file extension is rather rarely used and includes different formats for the applicable programs. The two most common formats are as follows:

• 40% of all LMS files use ZIP compression, so several files are compressed and saved in one LMS file. An LMS file includes 3 to 18 files. File names inside are always icon.svg, manifest.json, projectbody.json and scratch.sb3. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. A typical file size is 24 KB. The files contain the following words: manifest.json. A common filename is CA_python_line_following 2.lms. These files can be linked to line, gyro, following, projekt, python, girl, follow and code.
• 10% of all LMS files start with the bytes LmsMEDUSA 1 crucial for this file format. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. LMS files can be up to 260 MB in size, but are often around 480 KB - 75 MB. Certain words are almost always found in the files, such as LmsMEDUSA 1 and BinaryI486_v2.

All other LMS files (50%) have no uniform format, frequently e.g. XML, LMS, LUMERICAL and CHIT. They are often associated with christmas, gospel, astronamars, pingerbee, cuber, mind, mode or ofdl.
