HTC One SMS Backup File with no Extension Restore issue I backed up my SMS an year ago via HTC One phone's messaging application. The backup file that was created on SD card had no extension and its name is "SMS_nai_SD_20160625_701301_0".

I was never able to restore that backup but I now need one of the messages in backup and have already lost the phone. If I open the file in notepad, it starts with "HTCMSGBACKUP_V1" and rest of that are special characters. There is another thread related to same issue that suggests either restore the messages or use emulator. I was wondering is there any other way to handle that if we know the starting characters of the file.

Thank you.
Just changing the file extension will not help. As far as I know it's just some kind of encrypted text file. It's either a htc or an android specific file. In order to restore a message from that file you need an android device. It might work with the stock android sms app in an emulator but probably not. I suspect that it's only going to work with htc sms app.

[edit]:
The backup file is an encrypted sqlite database file not just some text file.
