Q&A for How to Remove the System Volume Information Folder from a Flash Drive

It might be that the system volume information was already deleted or that the command you wrote was in the wrong format.

Windows recreates this file every time you plug in. So you actually delete the folder but Windows makes a new one.

"Clean Slate" that folder using admin commands. You can also scan for other folders like that using sfc/scannow in the admin prompt.

Use the elevated command prompt. Or right-click on cmd and choose "run as administrator." On UAC prompt, press "Yes."

If your flash drive or other device is write protected, there is nothing you can do (you need to be able to write to the drive in order to remove the folder). You could also try running CMD as administrator (search for CMD in start, right click, run as admin).

/s removes all directories and files in the specified directory, including the directory itself, often referred to as a directory tree. /q enables quiet mode, ensuring you are not prompted for confirmation when removing a directory tree with /s.
