There is a folder on the server, and I need to use a script or batch command to check which files have been modified by someone.
How should this be done, experts?

You can use the DateLastModified property in VBS to determine it.

In batch processing:
%~t1 expands %1 to the file date/time. This time is the last modified time.
The creation time can be seen with dir /a /t:c.
So, depending on the situation, you can output the creation time or last modified time of all files in the folder, and then compare them when needed. But the creation time or modified time of files or folders can be tampered with, so this method is not very reliable.
A more precise way is to use an md5 tool to generate md5 values for all files, and then compare whether the md5 values have changed when needed, in order to determine whether they have been modified. Of course, there is also a lot of specialized file read/write monitoring software on the Internet. . . .

You can record the files by modification time as a backup, and compare them with the next recorded set.
(Because if any file is modified, its modification time and file size will definitely be changed.)
If the files are relatively large, that is, if there are many lines, then the difficult part is comparing the two files.
If you........really have trouble.....you can refer to the exe, dll, inf program snapshot comparison (checking whether they were modified by a virus) in Computer System Maintenance

I made one in DOS to detect all changed files under drive C:, using the fc command to compare the file lists from before and after
crea old ↓ cls old ↓ see a~g ↓ SYS a~g
Create original list ↓ Clear original list ↓ View all result sets↓ View SYS type set
crea new ↓ cls new ↓ exe a~g ↓ ... a~g
Create comparison list ↓ Clear comparison list ↓ View EXE type set ↓ View custom set
fc a~g a~g ↓ cls result ↓ dll a~g ↓ menu
Compare result sets ↓ Clear result set ↓ View DLL type set ↓ Return to main menu
