How to find a file through cmd and replace it with another one?

Question

Command line

Hello!
Please tell me how to use the bat file to search for a file on all disks and replace it with your own? For example, I have a 1.txt file (it is somewhere on one of the C, D or H drives) and I need to somehow automatically find it and completely replace it with 2.txt. That is, remove it and replace it with 2.txt

Answer 1

dir /s/b 1.txtwill search through all subfolders. For each disk you will need to call.
You can iterate through all found using for.
But be warned, this will be VERY slow.

Answer 2

for /f "tokens=*" %%i in ('fsutil.exe fsinfo drives') do set _list=%%i
for %%i in (%_list%) do (forfiles.exe /p %i:\temp /s /m test.txt /c "cmd.exe /c copy /y c:\windows\win.ini @path")

forfiles.exe /?
FORFILES [/P <путь>] [/M <маска_поиска>] [/S]
         [/C <команда>] [/D [+ | -] {dd.MM.yyyy | dd}]
