Why are the files stored in the USB flash drive always inexplicably corrupted?

You've bought an expansion disk.

Expansion disk refers to the use of relevant software to make the small capacity of the U disk displayed on the computer with a large capacity (such as 512M display into 2G).No.

The excess memory is not used normally, and the files stored in this USB flash drive will be corrupted as long as the actual capacity is exceeded and then copied out.

The remaining ones show unallocated fake capacity regardless of that.

b.Take Action: Action - Apply Changes.

C, after the PM program is executed, the USB flash drive already has a usable space equivalent to its actual capacity, and it's done!
