After using COPY /b 1.jpg+2.rar 3.jpg... 3.jpg can normally display the content of 1.jpg; Then renaming 3.jpg to 3.rar can then normally display the content of 2.rar; But my question is: How to decompose 1.jpg and 2.rar from 3.jpg? copy /d?

This operation is obviously irreversible.

It can only be separated by judging through the file header.

It can be solved! Who can post one up and see what good methods there are? (The total file size should not exceed 65280 bytes, that is 64K. If there are pictures first, the pictures should not exceed 65280 bytes) Please use batch processing (can use debug) to solve it! Do not use other third parties. (Pictures are the key) [ Last edited by ZJHJ on 2010-6-3 at 16:18 ]

Search for Rar! in WinHEX. The previous content was JPG, and the subsequent content including RAR! is a RAR file
