Q:

Removing SMScontactsbackup folder

I have read a similar post here
Accumulation of APK's?
I have about 8Gb of my SDcard on a Samsung Galaxy S7 used by the apks folder within the SMScontactsbackup folder
Now from what I have read and understood (which may be wrong)
This apks folder contains the installation material for new versions of Android apps. Surely the apk should be deleted once the app upgrade has been successfully installed? 
I don't have the Super Backup and Restore installed on the phone (which some people claim is the cause of the problem) but I can't be sure whether that app was installed in the past and now removed.
My question is
How do I delete this apks folder and its contents which are taking a large part of my SD card? I could not find those instructions anywhere - but maybe I missed them 
Thanks
Clive

A:

Super Backup and Restore application creates a folder named SMScontactsbackup on internal storage. The application is used to backup and restore contacts, call logs, sms, apps etc. 
Each items are kept in separate folders.
The app also saves  each  app's previous apk's which are updated through play store.
You can delete this folder by these methods.

By removing Super Backup and Restore application from your device, it will also ask permission whether to delete folder and it's contents.
Using any file manager app (here Samsung file manager for Samsung devices),you can delete that folder from internal storage. (N.B if Super Backup and Restore application is not removed, then folder will be created again ).

Note: You need to make sure that, you've restored everything before removing app/ deleting folder.
