how to open a .hbk files which contains the sms backup from htc one s I can't open the backup of sms because after sending it on my mail I discovered it's a hbk file. How can you open this type of file? 

I need to print them! thanks
In case you no longer have a copy of the SMS on your phone, but have backed-up the SMS to your PC or email, you need a combination of t0mm13b's comment and bmdixon's answer.

As  mentioned, it's not possible to open .hbk files on the PC. What you can do is:


Restore the .hbk to your phone as SMS


In your SD card, make sure you have a folder called sms_backup. If this doesn't exist, create it. This will be in the same level as the Android folder.
Copy the .hbk file to the sms_backup folder
Restore the SMS from the SMS settings

Export the SMS as .xml using SMS Backup &amp; Restore
Email the .xml file to your PC
After downloading the .xml file, open it from a program like Notepad or Microsoft word, and print.


Take note that XML has a weird structure, so expect to see a lot of tags (in greater than and less than signs).
