I'm using xcopy to copy across a fairly large file structure from A to B. Whenever I run the batch script I have (see below), it copies all the files from A to B that are newer than the destination files. Trouble is, when I delete a file in A, it does not delete the file in B when I run the script. I would like for this to happen.

xcopy "C:\a" "C:\b" /d /e /y

There is a command called /u that copies files from Source that exist on Destination only. I want the total opposite of this, where you delete files from Destination where they do not exist on Source.

Basically, I want A and B to be exact copies after I run the script without having to actually delete B and copy everything.

Any tips?

You're talking about synchronization. And its not going to be just one command.

You need to loop through all your source files, compare them to your destination files, and determine what is left on the destination that isn't on the source, then issue a delete for each one.

You need to write code logic, not just issue a command that already exists.

Makes sense, means I can stop wasting my time looking for a pre-existing solution then and get cracking. Thanks!

Ok I've tried looping through one of the files and checking if the file is equal to xasdas.txt, which I know is there, and if it finds it, print out the file name.

FOR /R C:/b %%i IN (*.*) DO (
 IF /I %%nxi EQU XASDAS.TXT (
	 ECHO %%nxi
 )
)

The output I am getting is hundreds of lines of the if loop repeated constantly, and I mean it is literally being printed out as you see it:

Spoiler

C:\A>IF /I %%nxi EQU XASDAS.TXT ( ECHO %%nxi ) )
C:\A>IF /I %%nxi EQU XASDAS.TXT ( ECHO %%nxi ) )
C:\A>IF /I %%nxi EQU XASDAS.TXT ( ECHO %%nxi ) )
C:\A>IF /I %%nxi EQU XASDAS.TXT ( ECHO %%nxi ) )
etc...

Even if I place an echo before the IF, it actually prints echo on screen too rather than actually doing it, so I feel as if I'm using something wrong...

Just FYI this is my first time really using batch files/MS-DOS properly, so bear with me

Any tips?

I'm not help to you with batch files. Sorry.
I would just write a little application in C# to do this.

[MrSooty]

I would too but now I'm committed! Thanks anyway

Slight necro, but the solution is to use Robocopy!
