Sorting by size would have to be a feature of the particular message app. I've not heard of anyone do that, but in principle it could work. (*) OK, in principle if you were rooted and know your linux you could move the database to SD and put a soft link in its original location to the new one. Whether you can view the backup will depend on what app you make the backup with: there is no standard, so each will use its own format.īut as for what you are really wanting, to tell Android to move the SMS/MMS database to SD and then carry on as before, I'm sorry but that's not possible(*). If you can find an app that lets you view the backup (either on Android or a computer) then you could back up, save the backup wherever you like and then delete the threads or messages you don't need to read in your message app. You can of course make backups with one of the myriad SMS backup tools. If you don't have root you can't see, copy or move that file anyway. If you had root access you could copy it to SD, but the message system would still use the copy in /data/data and if you removed that no SMS/MMS app would be able to see your messages. The Android message database (which is common to all SMS/MMS apps) lives in /data/data and you can't reassign its location. The short answer is that if you still want to be able to view them in your message app (Textra I assume) you can't. 5GB? Presumably a lot of these are MMS, because I can't imagine how anyone could amass 5GB of SMS.
