Find the file you want to upload the image, for example, you need to upload the a.exe file, you can first compress it into a a.rar file and place it under the d: disk, and at the same time prepare the image file b.jpg as the carrier, and place it under the d: disk as well. Step 2: Open a command prompt window, enter "d:" to locate the D drive, and then enter the "copy /b b.jpg+a.rar c.jpg" command Command explanation: Use the Copy command to combine a.rar and b.jpg files to generate a new image file c.jpg containing other programs, here you need to place the image files required for the combination in front. The c.jpg files obtained after combining can be opened and viewed using Paint, but the hidden a.rar files cannot be seen.
