Lost my internal data... but it's still there? [SOLVED]

I went from LiquidSmooth to Jelly Beans (a touchwiz-based rom) to LiquidSmooth again. Unfortunately, it looks as though my internal sd card was wiped in the process. However, my internal SD card is suspiciously full of data.

}
No matter how much digging I do, I can't seem to find why the internal storage is so full despite all the visible folders accounting for hardly any space at all.
These combined folders only make up 781 kb of data.
Are my old files still hiding somewhere in my Galaxy S3?
EDIT:
I found the data! It was hidden in mnt/shell/emulated.
Hopefully this helps someone in the future if they run into this same problem.

Trying to copy files and suddenly stops?

I'm trying to copy files, to my SD card via USB storage, and as soon as a couple of minutes go by, the transferring just stops. Doesn't matter what I try to copy (music album, game data, ROM, etc.), same result. Also tried different USB ports and same thing happens. Not sure if I make any sense, so I hope these pictures can help.

After (notice the "free space" details disappear and now says FAT32)
If it helps, I'm using a Samsung Epic 4G running CM 10.1 (4.2.2), SanDisk Ultra 16GB microSDHC Class 10.

Tried another cable?

Help with Storage/Partition!

As you can see in the screenshot below the OS Occupied size is 8.63 and internal storage or partition size of ext4 is just ~23gb, Very less for a device with 32gb storage.
So i dig into this problem and found that 8gb includes my TWRP backup i took a long back ago, Now i want to delete it but i can't find it. I tried for searching backups in TWRP but there's none i think TWRP looks in ext4 that is it only searches in 23gb, not 8gb.
I spent the whole night yesterday to fix it but no success. I want my ext4 partition to take the normal space that near about ~29-30gb and i want to delete that backup. I want my partitions to be as it was before (its fked up)

Why is Adoptable Storage Taking up So Much System Storage?

I have recently switched to Adoptable Storage using 128GB SD Card. However upon successfully completing the steps, I found that not much space is available. Most of them is taken away by System Storage as shown in the image below in "About Phone > Storage".

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
However, looking at the File Manager all seems perfectly fine as shown below
My Xiaomi Renot 5 is not rooted nor bootloader unlocked and I have no plan in doing so.
The ROM being used is still the latest Official MIUI 11.
I sincerely hope that anyone has a solution for this problem and I don't really want to resort to Factory Rest if possible.
Thank you in advance

[Question/Help] Phone storage only shows half capacity in PC in backup

I got a Oneplus 5t with 64gb of storage with only 500mb left.
I backed it up with an adb command: adb pull sdcard
However, it only showed half of the storage
which is around 32gb in the backup folder and file explorer.
The used capacity shown in the phone is 63.5gb which is almost doubles
I afraid that the backup is not including everything
I wonder whether this is a issue related to difference in counting bytes on windows and android.
Please note this oneplus's bootloader is unlocked but isn't root. I lost all my data after it as my backup didn't work.
