Rezound Storage and files question

[DaDroidDude]

Hi all.

When I hook my Rezound up to my laptop via usb cord and choose "disk drive"
I get three drives that show up in my windows explorer
CD DRive (G) CDROM - 0 bytes free of 6.71 MB
Removable Drive (H) - 10.3 GB free of 10.4 GB
Removable Drive (I) - 3.11 GB free of 14.8 GB

I assume that the drive G is the "ram" of the device,
drive H is the internal storage and drive I is the 16gb removable sd card.
Correct?

My question is that, on the drive I, there is a nandroid folder that is taking up 4gb of storage space.
It has one folder in it, HT1A1S22240, that has 4 subfolders in it, each with the same files in them.
boot.img, cache.img, data.img, nandroid.md5, system.img.

Are these operating system files that are in use of files that were downloaded for previous custom roms?

Can I delete them?

Thanks
B

I: is the sd card
G: is the internal memory

Sounds like to me that is a Rom folder, take out the SD card and see if the phone still works.

Well, duh!
I should have thought of that.
I hate when there are super simple solutions that I miss.

But it was late at night.
Yeah...

I'll go with that.

Nandroid folder is backups, which are large in size, has nothing to do with os running
