Hide file will be displayed.

When I connect Flash Memory Shows about 2GB is full



But when I open flash memory any file will be displayed.


However, the file system will appear

Anyone can not help me in this context

Scan your flash memory drive with Wiztree (free) to see if it shows the files in the System Volume Information folder.
They have a Portable Zip available, so you don't need to install the program, just unzip and run it.
Antibody Software - WizTree finds the files and folders using the most disk space on your hard drive

Maybe you have System Restore enabled for this drive ?

I clicked on your links, and i get an invalid attachment error
So i can't see what you see.

i install and runs WizTree software but not found my flash memory
my flash memory on drive L:\


but L:\ not in list of WizTree software

It looks like the attachment issue is fixed, so i can see your screen prints now.
In post #1 it looks like your flash stick is the [M] drive, not the [L] drive

Can you post a screen print of disk management ?

What are you doing, such as attaching/removing a flash drive ????
Booting with what devices attached, etc ????

my flash drive is L:\

I attached a USB flash drive and tried a few different tools.
I don't see a System Volume Information folder using any tool i tried.

My flash stick is FAT32, yours is NTFS.

I would copy all data i want to keep to another device, reformat the stick, and copy data back.

Did you look at System Restore to see if you have it turned on for your flash drive ?
