Using the functions provided by Win7 to encrypt the U disk

The small U disk is the preferred mobile storage device for many friends, but because of its small size, the U disk is also very easy to lose, and the important data and information stored therein are also It is likely to be leaked. Although the use of encryption software can play a protective role, it is more troublesome. This problem has also plagued Xiaobian for a long time. After starting to use Windows 7, I found that a function that comes with Win 7 can encrypt our U disk. BitLocker security is already available on Vista, and Windows 7's BitLocker is more powerful. It does not require users to modify the Group Policy and other complicated settings. Just log in to Windows 7 as an administrator and use it. After inserting the USB flash drive, right click on the USB flash drive in “Computer" and select “ Enable BitLocker” from the popup menu. At this point, a “BitLocker Drive Encryption” wizard will pop up, and you can choose the way to unlock the drive as needed. Xiaobian recommends that you choose “Use password to unlock the drive”. After entering the password twice in succession (the password is at least 8 characters), click “Next”. In order to prevent the password from being forgotten, BitLocker will save a recovery key to another drive or print it. If you choose to save the key, you will get a text file with the file name <BitLocker recovery key ***.txt”. Finally, click “Start Encryption” and BitLocker will start encrypting your U disk. The time required for this process will be determined by the capacity of the encrypted U disk and the size of the storage file. After the encryption is completed, you can see that our U disk has been "locked" by going back to the drive list! After inserting the USB flash drive into the computer in the future, a prompt box of “BitLocker Drive Encryption” will pop up first, and the USB flash drive can be used normally only after the password is correctly entered. In the case of Win 7 using BitLocker encrypted U disk inserted into the XP system computer, it can also be protected by BitLocker encryption. Unlike Win 7, you can open the U disk first under XP, but the files inside need to input the password correctly. Can be opened in the way of "BitLocker To Go Reader", so friends who do not have Win 7 do not have to worry about not being able to use the encrypted U disk
