How to save SMS as txt file?

Landlord, Happy New Year! Me too, 76 10. There is an ultra-simple method. Press the pen key and delete key (C) at the same time after opening the short message. The phone will automatically save the message in Notepad (there will be no prompt, please try). If you want to get the txt file on your mobile phone, install the SmartFileMan file manager, and save the short messages to be converted into txt files in the draft box in MMS format (method: click Send in the short messages saved in Notepad, select the MMS being sent, and click Close directly after loading). Then open the installed SmartFileMan file manager and click "SMS Inbox" to find the file with suffix. Txt is in it, copy it to the folder you want to save on disk E or disk C, and finally delete the MMS in the draft.
