I dug this up.

This should do it, though it's probably not the cleanest method. Tests alright on my computer.

for /F "tokens=*" %P in ('dir /b /s myfile.txt') do copy /Y .\myfile.txt "%P"
If you're running it from a bat file use %%P instead of %P.

EDIT: I corrected the command to work with file paths that have spaces (notice the quotes around the last parameter). Also when running the command you'll always get this error:

The file cannot be copied onto itself.

.
Just ignore that, because it doesn't hurt anything

Here's a batch file version that I called subupdate.bat:

@echo off
if "%1"=="" GOTO End
for /F "tokens=*" %%P in ('dir /b /s %1') do copy /Y .\%1 "%%P"
:End

Then you can invoke it as such:

C:\root_dir_for_changes\subupdate.bat my_file_to_update.txt
The file cannot be copied onto itself.
        0 file(s) copied.
        1 file(s) copied.
        1 file(s) copied.
        1 file(s) copied.

For a BAT file:

Q: Where do you input the file name? For instance, what would the code look like if the file you wanted to copy/replace was named "test.xml"?

A: If you're running it from the command prompt then CD into the root directory containing the most recent "test.xml". Then run the following command:

for /F "tokens=*" %P in ('dir /b /s test.xml') do copy /Y .\test.xml "%P"
If you're running it from a bat file then the bat file should contain:

for /F "tokens=*" %%P in ('dir /b /s test.xml') do copy /Y .\test.xml "%%P"

If you're using my subupdate.bat described in my first post then CD into the root directory containing the most recent "test.xml". Then run the following command:

Code:

subupdate.bat test.xml
