How to encrypt Win7 folder Win7 folder advanced encryption skills

Everyone’s computer has some sensitive personal documents or important commercial materials. Generally, some technical means are used to protect files from being seen by others, especially in environments where computers are used by others. Under the protection data is even more important, but most of the folder encryption methods introduced on the Internet are implemented by means of third-party software. The following article introduces the Win7 folder encryption without using software. The common protection method on a computer is nothing more than encryption, but the encryption method can be either simple or complicated. The easiest way is to set the folder as a hidden attribute. People who don't know much about the computer are basically blocked out of the door. Complex ones can be encrypted with professional encryption software or even hardware. In the Windows 7 era, Microsoft gave us a very good encryption method — — BitLocker, which can encrypt any hard disk partition or mobile storage device. However, this feature is also inconvenient, it is only available in the Ultimate and Enterprise editions, and the computer purchased by the user is usually pre-installed with Windows 7 Home Standard and Premium. If you just want to hide some personal information files on this machine, you can try the following tricks, it does not require you to install third-party software, it is very convenient, and supports the latest Windows 7 system. The specific method is as follows: The first step is to find a folder that is not easy to attract attention, so do not choose a folder like game movie, and this folder will not be easily deleted, but do not use the system partition directory, because in Windows 7 will cause encryption failure due to problems such as permissions. The second step is to create a new TXT text document in the selected folder (the name doesn't matter), then open the document and paste the following into it: cls @ECHO OFF title Folder computer PepsiNet if EXIST "Control Panel.{21EC2020 -3AEA-1069-A2DD-08002B30309D}" goto UNLOCK if NOT EXIST computer Pepsi network goto MDLOCKER :CONFIRM echo Are you sure you want to lock the folder(Y/N) set/p "cho=>" if %cho%==Y goto LOCK if %cho%==y goto LOCK if %cho%==n goto END if %cho%==N goto END echo Invalid choice. goto CONFIRM :LOCK ren Computer Pepsi "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Echo Folder locked goto End :UNLOCK echo Enter password to unlock Folder set/p "pass=>" if NOT %pass%== Here is the password goto FAIL attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" ren " Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Computer Pepsi Echo Folder Unlocked successfully goto End :FAIL echo Invalid password goto end :MDLOCKER md computer Pepsi net echo computer Pepsi network created successfully goto End :End Description: in the code "if NOT %pass%== here is the password goto FAIL" The "here is the password" needs to be replaced with your own password combination, pay attention to the space between the reservation and the equal sign. The third step is to save the text and then change the suffix to the .bat format. Double-click it to run it once it is finished. At this time, a folder named “Computer Pepsi Network” will be added to the location of the file. The code in the code "Computer Pepsi" can also be replaced with your favorite folder name, a total of six, be careful not to miss. Supplementary note: In order to maximize the application of this string of code, please try to use English letters or numbers, so some of the above-mentioned code retains English in the prompt text, and the folder is changed to Chinese for convenience. The fourth step, when the folder is generated, double-click the bat file again and you will see the following prompt: Ask if you want to encrypt this folder (refer to "Computer Pepsi" folder).

Press the Y key to enter the car encryption, the N key is not encrypted (Y and N are not case sensitive), and after selecting encryption, the folder will disappear. At this point, even if you change the system folder setting to "Show hidden files, folders, and drives", you will not see this folder. Trying to enter the folder name directly in the address bar will not be accessible.

The fifth step, when you need to access this folder, you need to decrypt first, still double-click the bat file, you will see the following command window prompt: ask you to enter the unlock password.

Enter the password and press Enter. Then you will see the original file appear again, then what should you do? This bat file can be copied to any other folder for use, so we can put it in other places after encryption and save it. It needs to be decrypted and copied. The reason why it is recommended to do this is because the file contains the password directly. On the other hand, the existence of such a bat file in the folder will cause some people's curiosity. It is not easy to be discovered after removal. There is a secret here. In fact, friends who have learned the dos command and batch file before, I understand what happened in the above code, the encryption method is actually not complicated, first rename the encrypted folder to a special name: Control Panel. 21EC2020-3AEA-1069-A2DD-08002B30309D}, and then change its properties to hidden + system, adding a judgment statement is only a batch file to complete the encryption and decryption work. Of course, this method also has its shortcomings. Although you can't see the encrypted folder under Windows Explorer, you can still see it by using other third-party tools such as Winrar, and you can access the files inside. . So Xiaobian said in the first step, choose a less conspicuous folder to maximize its effectiveness.
