Use Win7's own function to encrypt the U disk to prevent important information from leaking. The

U disk is the preferred mobile storage device for many friends, but because of its small size, the USB flash drive is also very easy to lose. The important data and information stored in it are also likely to be Give way. 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. A “BitLocker Drive Encryption” wizard will pop up, and you will be prompted to unlock the drive as needed. You are advised to select “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 U disk into the computer later, it will pop up a “BitLocker Drive Encryption” first. In the prompt box, the U disk 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.
