Phone Warning Says Almost Out Of All 11GB Storage And Will Stop Working But Can't Find 10GB+ of Internal Storage Files To Delete

[startac4]

I'm getting warning that running out of storage and need to delete things or the phone will stop working.. When I connect phone to computer it shows only about 1/2 GB out of 11 GB free in internal storage (it shows shows over 100GB free in the card storage). But when I display the internal DCIM folders on computer there's only about 500 MB of files in the folders. The three non-DCIM folders are empty. I can't find 10GB of files to delete. Why is it warniing me it will slow down because I'm out of storage and what do I do to free up storage and keep phone working? Why can't I display these 10GB of files/folders?And how, just in case, do I delete the TRSH on the phone? There's no "menu" icon on the MY Files so I can't go to TRSH there. I found TRSH in Gallery but it says its empty.

This is the third time I'm trying to post this and it has not shown up in the forum. What do I have to do to get this posted?

How many apps have you run though? Sometimes it is the apps.

Have you embled usb transfer on your cell and connect it through your windows? That can really help things through.

I've connected it with USB to computer but I don't see 10GB of files that I could delete.

Have you checked the folder entitled "DCMI?" That is your photos.
