Hello

The operation is as follows

Find a Jpg file

Find a file and compress it into rar. The capacity cannot be too large... …

Store the two files to the D drive…

. (Win R) Select the run box.

Enter Cmd

Press Enter and enter the following...

copy/b?d：1.JPG? ?d：2.rar?d： 1.JPG

The two d's represent the disk where the two files are located...

1.jpg is the file name. 2.rar is the name of the compressed file

The new picture 1.jpg obtained already contains file 2.rar

------------ -----------------------

Disadvantages: The file cannot be too large. I have forgotten the details. I estimate it will be around 200k.
