My pendrive with exFat file system copied files missing

Hi,

If your pen drive storage space appears to be used, your files may be hidden. To show your files, in File Explorer, go to View > Options > Change folders and search options.

Select the View tab, then in "Advanced settings" check Show hidden files, folders and drives and click Ok to apply.

Alternatively, open Command Prompt (cmd) and enter the following:

attrib -h -r -s /s /d g:\*.*

Replace the letter g with the one corresponding to your USB, then press Enter.
