Editor to share with you how to batch bat directory comparison tools, I believe that most people do not understand, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Update log:

V4:

1. Added the progress display of the calculation

two。 Found the new version of md5sum.exe, no dependence on dynamic libraries.

Tool 1: md5comv4.bat accepts two directory parameters, calculates the md5 value of each file in the two directories, and gives the report file md5v4.txt, how to use it:

Md5omv4.bat

According to the report file md5v4.txt generated by md5comv4.bat, you can find two directories

1: a file with the same name and md5

2: files with the same name but different md5

3: files with different names but same md5

4: files with different names but the same md5 in the same directory.

Note:

1:md5comv4.bat does not accept directory names with spaces in the path, but can accept file names with spaces

The calculation of 2:md5 is completed by md5sum.exe

The 3:md5comv4.bat runtime produces a large number of temporary files that are automatically maintained by tools and do not have to be cleaned up manually.

This tool is command-line, text interface, for friends accustomed to using the graphical interface, may not be convenient, therefore, friends accustomed to using the graphical interface is not recommended.

The code is as follows:
