Root Question about Android & App_Manager folders

[thecdn]

My internal 4gb sdcard currently has about 147mb left and I'd like to clear some space off it. App2sd pro tells me there are no moveable apps on the internal sdcard.

The Android folder is using 38% of the space and has one /data folder. The biggest folders in that are:
com.amazon.venzia
com.glu.gladiator_nr
com.elevenbitstudios.AnomalyWarzoneEarthHD
com.google.android.apps.currents

These seem to be filled with cache files. Is it ok to delete these?

The App_Manager folder is using 21% of the space and has App_Backups which consists of the folders user_apps & system_apps. How critical are these if I have both current nandroid and titanium backups?

Any ideas to clear up space would be appreciated.

If you have an external sd card, titanium backup can be set up to send backups there. Most apps wont see your external sd and will only use the internal sd, so its best to move what you can (backups, pics, music, etc) to the external sd. Sd cards are cheap now.

Its probably ok to clear the apps caches, but I'm not 100% sure.

Already done. TB and nandroid backups are on the 16gb external sdcard. As are all pics and music. Wish there was a way to move apps there.

Get rid of your music off your card. Install Google music on your pc, it will upload all your songs to the cloud and you can stream on demand with the google music app from the market. Also optionally keep an offline copy of anything you choose like play lists or albums so it doesn't have to stream them. I've been using it and it's pretty bad ass, you can log into any pc as well and it all travels with you.

You can also take the easy way out. Backup with TiBu, Format internal SdCard if that's the one filling up. You probably got data left over from apps no longer installed, flashing a rom can leave this sort of stuff behind.

What internal memory by the way? there's 2.
/data <-where apps install before apps2sd
/sdcard <-some apps cache stuff here, apps2sd moves apps here partially.

/sdcard/_External <-your real sdcard (up to 32GB)

It's ok to format the 4gb internal card? I thought it was associated with the LTE capability of the phone? There's nothing on there that's needed?

If you format it, then restore apps from TB, that will put back on it what is needed to function without the built up junk and the phone will carry on happily?

/data has almost nothing in it - 485kb of some widgets & skins I don't use anymore

/sdcard <-some apps cache stuff here, apps2sd moves apps here partially.

I don't see an /sdcard folder other than the sdcard itself. The /Android folder is full of cached stuff.

/sdcard/_External <-your real sdcard (up to 32GB)

This has my pics/docs/music, TB backups (changed folder loc in TB), and nandroid backups. Currently 5gb free of 15.
