Q: Siri can't find my apps

You have to use iPhone explorer or another file browser or iFile.

Proceed with caution, there are reports of losing all apps.  I myself tried just deleting the .csstore file but it didn't work and I don't have the time to deal with losing all my apps then waiting for them to maybe or maybe not come back.

I deleted only:

/var/mobile/Library/Caches/com.apple.mobile.installation.plist

Some apps were missing. Rebooted and did a respring and all was back to normal.

How do you delete these on an iPad 3 that is not jailbroken?  Thanks.

you need ifile go to cashes or find trash   - and there you find ur file

and go to appcake install filetranfer go to same directory and restore move ur files back to prew location

/var/mobile/Library/Caches
