Through the following methods, you can easily prevent RAR files from being opened and ensure file security.

Method 1: Set "Open Password"

When compressing files, you can use software such as WinRAR to set an "open password" for the RAR file, which can ensure the security of the compressed package. The file can only be opened after entering the correct password, preventing unauthorized access.

Setting method:

1. Select the file or folder that needs to be compressed, right-click the mouse, and select "Add to compressed file" in the WinRAR option list.

2. After the [Compressed File Name and Parameters] dialog box pops up, click [Set Password]. When the dialog box pops up again, enter the password you want to set in the password field, click [OK] and then re-enter the password. It's set.

According to the "Method 1" setting, the files in the RAR compressed package cannot be opened at will, but the file names in the compressed package can be seen. If you want to prohibit opening the compressed package at will, and do not want to leak the contents of the files in the compressed package, You can set the file name to be hidden.

Setting method:

1. Follow "Method 1" to compress the file and set a password. When the [Enter Password] dialog box pops up, enter the password you want to set in the password field, check the [Encrypted File Name] below, and then click [OK] 】It is set.

Setting method:

1. Put the RAR compressed package into a folder, then rename the folder and add the following code after the file name:

.{20d04fe0-3aea-1069-a2d8-08002b30309d}

2. After adding the suffix code to the file name, you will see that the folder icon changes to the "This PC" icon.

3. Click to open the folder with the modified name, which also jumps directly to the "This Computer" folder. You cannot see the original RAR compressed package, so you cannot open the compressed package.
