I’m trying to password protect a USB drive, or password protect a folder on a USB drive, and I’d like to do this for free. I’d like to take the flash drive with me, and a password be required to access the drive or a folder(s) on the drive.

I know you can use 7 zip to encrypt files/folders, but installing Office from the USB after unlocking folder encrypted by 7 zip the install doesn’t work.

I’m trying to use Bitlocker to go in Windows, but for some reason no matter what brand of flash drive I use, the drive never shows up even though there is a flash drive plugged in the PC.

This is Windows 10 Enterprise, and I’m logged in with the Administrator account on the PC, but still don’t see the drive.

I don’t believe I’ve ever used Bitlocker before, but what I want to achieve is having to use a password to access the USB drive. I hope this can be done without using a program.
I’ve tried a few ideas from this website,, but no luck. The PC I use does have TPM 2.0, and this PC isn’t on a domain so there are no restrictions, just a stand alone PC.

I know there are “free” USB tools out there, and I’ve tried a few of these, but it seems like every password software you use, you have to have software installed on the PC, or run a program from the USB drive itself. The password software approach can cause anti-virus to go off.

I think experimenting with the local group policy may have made these screens come up:

I choose encrypt this drive using Bitlocker and get this screen, and get the screen below. I’ve quick formatted the flash drive, and did a full format on the flash drive to still get the screen. Do you have to create another partition on the flash for Bitlocker?
