Why would you copy a file to more than one folder? That seems like a waste of disk space and sounds like it's bordering on a bad idea. But, there may be some legit reason for doing it.
The command line tools will only target one destination folder at a time, so you're going to have to generate a list of directory paths, then iterate over that list, running a copy command to copy the file to each of those folders, one at a time.
You do can this in a batch file with the following command:
for /f "tokens=*" %%G in ('dir /a:d /b /s') do copy sourcefile.ext "%%G"
There is a teensy problem with this. Any directory path with a '.' character in it will be treated like a file extension. For example, a folder with the name "Software 2.31.2" will be seen as "Software 2.31" (note the missing 3rd number.)
So if you have periods in your folder names, you can run into problems.
