Text /Liu Ting

We know that NTFS file format can achieve encryption of the folder, enhance the security of the file, but because of the details of NTFS The content is more complicated, so the files encrypted with NTFS often have some problems due to improper operation, such as the loss of the user name, the loss of the file password, etc., which will bring a lot of trouble. Today, we will come together to discuss this issue.

Q: I am using Windows XP system. After encrypting files in NTFS format, the color of the folder becomes light green. If I don't want it to display other colors, just like other folders. , it can be yellow, how can I recover? By the way, if I want to change its color display, can't it work?

A: If you don't want the encrypted file to display other colors, you can select "Tools→Folder Options→View" on my computer and cancel the "Show encrypted and compressed NTFS files in color" checkbox. That's it. If you want to change the color of the file, you can find "HKEY_CURRENT_USERSoftwareMicrosoft

WindowsCurrentVersionExplorer" in the registry, then create a new binary value "AltEncryptionColor", change its RGB mode, directly input the color data, and then restart it. It is.

Q: Can the folder encrypted by the file be hidden from other users, and only I can see it?

A: If you want other users to not see your files at all, you can set the folder to private and specify other users as restricted users. In addition, in the file properties window you can also set whether other users can allow the use of the folder, whether there are modifications and delete permissions, NTFS file encryption is still very good, please feel free to use.

Q: My computer has set up multiple users and set the user access password for the corresponding folder. One time I accidentally deleted one of the password users. Now the user can't encrypt the file. Visited, what should I do?

A: This problem is a headache, see if this can be solved: first log in as Administrator, in the "View → Advanced Settings" list in the folder options, "Use simple file sharing" to remove, and then Switch to the lost user's folder, open its properties window, under the "Security" option, you can see any users that are not allowed to access, click the "Advanced" button to enter the advanced settings interface. Switch to the "Owner" option, if there is a list of your users, select it, and select the "Add permissions and object owner" checkbox under the interface, click "Apply" to add settings, this You can see your name in the Permissions tab so you can access the file.

Q: I often hear people say that it is very important to decrypt the encrypted file. Is it possible to backup it to other partitions, or other places, or use it as usual?

A: In the case of ensuring that the certificate decryption file is not destroyed, it is no problem to put it anywhere. Even if you reinstall the system or change the user, as long as the certificate decrypts the file, there is no problem. It is possible to decrypt the file normally.

Q: The e-Cert that we often see can be used and modified as long as it is obtained, so if I have a very important file, then others can access it using the certificate file. Not very unsafe?

A: You don't have to worry about this. When the certificate decryption file is exported, you can choose password protection when you are confidential. The exported certificate can't be used without a password, so your worries are gone. The certificate file is very important and it is recommended that you keep it properly.
