You can't call yourself a computer geek if you don't know this trick. It's always a good idea to carry your important files in a usb instead of carrying the whole laptop. But i don't like everyone prying my files on usb. So i use a password for anyone who tries toaccess my ubs drive. It also helps to secure my data from wrong hands in case of theft.
There are lot of softwares out there(most of which are paid apps) to help you with this but if you are using windows you don't need any app. Here is what you have to do to password protect your usb flash drive.
Steps:
1. Plugin your USB, click on Start & type BitLocker Drive Encryption and launch that app.
2. Now look for your drive and click on Turn on Bitlocker. Windows will ask you for a password, give it one and click next and save the password somewhere safe if you want.
Next time anyone tries to access you usb, he would have to crack the password.
