1. To export the text chat record, you need the mobile phone root, and then you can record the text chat.

2. Download the root tool in the application market first and get the root permission of the mobile phone.

3. Then, connect the mobile phone to the computer with a data cable and open the folder \ data \ data \ com.tencent.mm \ micrimmsg.

There will be a folder named after a long string of numbers or letters (there may also be multiple folders, and different folder names represent different QQ. If you log in to WeChat with different QQ, each QQ will generate a new garbled folder, which can be backed up for security reasons). There is also a systemInfo.cfg file in the folder, which is not backed up.

4. Then enter and find the MicroMsg.db file, which is a database file for storing friends' numbers, nicknames and chat records.

5. If you want to open it and export it as text, you can download a SQLite related software.
