When we come into contact with qm file, our first thought may be what file format it is. Qm file is actually a Qt translation file, which is used to support multi-language conversion of software. Qm is a unique format of Qt, which is usually included when the program is installed, so that the software can adapt to multiple languages.

Qm files are usually generated by special translation tools, which will extract all the strings in the program, translate them, and finally output qm files. When using the program, you can find the corresponding translation from the qm file according to the language selected by the current user, thus displaying the correct language.

At the same time, qm files can also be edited and modified by special tools, so as to achieve the customized effect. However, it should be noted that manual editing of qm files requires certain experience in program development and language knowledge to prevent unnecessary mistakes.
