I know this is not VBA, but honestly I do not know where else to ask.

I have a program that after installation required me to update 1 specific dll, in each of up to 16 folders it installs.

Lets say [as an example] that the program creates the folder
c:\program files\test and then in that folder there may be from 1 to 16 sub folders depending on install options.

It has a BAT file associated to do this easily but i do not understand the script and so am afraid to run it. The script supplied is : FOR /F "tokens=*" %%D IN ('DIR "C:\Program Files\amtlib.dll" /S /B') DO copy /Y "123.dll" "%%D"

Will this work?
Is it ok to run?

Thanks eds

ps. I need to install it on 23 pc's. likely each pc's will map the network cd drive so the install location will be variable. Will that recognize it?
