php editor Banana teaches you how to lock RAR compressed files, effectively preventing the compressed package from being changed or deleted at will, making your files more secure and reliable!
In order to prevent the file content from being tampered with, you can consider setting a unified "restriction protection" for the entire compressed package. However, if the number of files is large, setting them one by one will take a lot of time, and not all files can be successfully protected, so this method is not the best choice.
Today I will share a simple method that can protect RAR compressed files from being added, deleted and changed at will.
First, download the WinRAR compression software, open the RAR compression software through WinRAR, and click [Lock Compressed File] in the menu [Command] list.
.
After the dialog box pops up, you can see that [Prohibit modification of compressed files] has been checked, just click [OK].
.
After completing the above operations, the current RAR compressed file is locked. You can see that [Add] and [Delete] in the menu bar have become unselectable, that is, the compressed package cannot add files or delete files inside.
.
Under this setting, any file in the compressed package can be opened and viewed. If the file content is changed, a window will pop up when closing the file, prompting "Do you want to update the file?", but even if you select [Yes] 】Also unable to update and save.
.
After selecting [Yes], a window will continue to pop up, prompting [Locked compressed files cannot be modified].
.
Set "Lock" on the RAR compressed file and send it to the other party for viewing. Even if the other party uses a compression software other than WinRAR, you still cannot select [Add] and [Delete].
.
After the files in the compressed package are modified, the prompt "Locked" will still appear, which means the content cannot be changed.
.
In addition to setting "lock protection" for RAR compressed files, you can also set "password protection". The former protects the files in the RAR compressed package from being added, deleted, and modified at will; the latter protects the files from being opened and viewed at will, and requires a password to be opened.
It can also be set through WinRAR. When compressing the file, select [Add to compressed file].
.
After the window pops up, click [Set Password], enter the password you want to set in the new window, and click [OK].
.
Setting "lock protection" and "password protection" through WinRAR cannot be canceled directly, but we can decompress the file and recompress it into a new compressed package.
.
The difference is that the RAR archive under "Lock Protection" can be decompressed directly; when decompressing the RAR archive under "Password Protection", you need to enter the originally set password before further decompression.
.
So when setting up RAR "password protection", remember to save or remember the password.
If you really forget it accidentally, we need to use other tools, such as Pepsi Niu RAR Password Recovery Tool, which can help retrieve the password of RAR compressed files.

Import the RAR file in the tool, select the appropriate method and follow the prompts, and then wait for the password to be retrieved.
The above is the detailed content of Lock RAR compressed files so you don't have to worry about the compressed files being changed or deleted at will!. For more information, please follow other related articles on the PHP Chinese website!
