In addition to compressing files, WinRAR also has these useful functions

php Xiaobian Yuzai introduced that WinRAR has many other practical functions in addition to compressing files. WinRAR can help users encrypt folders, repair damaged compressed files, compress large files into volumes for transmission, etc., making it more convenient and faster for users in daily use. Through WinRAR's various functions, users can better manage and protect their files, improve work efficiency and data security.

Function 1: Lock files and prohibit adding, deleting or modifying files in the compressed package

WinRAR can set the [Lock] function to prevent files in the compressed package from being artificially added, deleted or modified and maintain the initial state.

Operation method: 1. Open the compressed file and click [Lock Compressed File] in the menu [Command] list.

.

2. After the new page pops up, you can see that [Prohibit modification of compressed files] has been checked by default. Click [OK] below.

3. After completing the above operations, the files in the compressed package will be "locked". As you can see, in the WinRAR menu, [Add] and [Delete] cannot be clicked or operated.

Modify the files in the compressed package, and you will also be prompted [Cannot modify locked compressed files].
