Use the Copy command to package images and compressed packages into images

Reference

 

Principle: The Copy command in Windows can combine two files into one.

 

Step 1: Put A jpg image and a RAR package in the same directory dir

 

Step 2: Open cmd.exe and enter the directory dir.

 

Step 3: Execute the command

Copy/B image .jpg/B + compressed package .rar/B target file .jpg

 

In step 4, the target file .jpg is what you want.

 

Note: JPG can also be changed to other formats, such as PNG, GIF, and BMP.

The compressed package format can also be changed to zip, 7z, GZ, etc.

/B indicates that the previous file is a binary file.
