WinRAR how do I expect compressed file size?

Multiple files or a folder without a combination of compression, no one knows how much they are compressed together, here we will apply to the WinRAR "estimate" function. Let's take a look at how winrar estimates the size of the compressed file.

Specific tutorials:

Please open the WinRAR window, select the folder or file that you want to compress, and then click the Info button on the toolbar, and in the Open window, click the Estimate button in the estimated compression rate function bar, and WinRAR will give you data such as compression rate, packet size, and compression estimate time. This is useful for compressing larger files or folders. You can also select the Auto start option if you want to automatically evaluate the file each time you click the Info button, winrar.
