HELP: Dos Programming to Copy file

Hi all
I am not sure where to post this question so I thought I just put it in general discussion, I hope someone can help me out

I need to create a batch file where it will copy a folder from C: drive to D: Drive

Now I read a couple copy command article and could not find one to set the parameter to skip all .. like - if the files already exist skip it

so the goal here I want to copy all files in C drive to D drive, and if the file already exist, don't overwrite it and instead skip to the next file.


Here is what I have

Code:

---

copy c:\test1\*.* d:\test1\*.* /y

---

/y = do not prompt for overwrite

ideally I want to say no to all / skip all , but only cope files that does not exist yet
is there a parameter for that?

Thank you

General PC is a good place for this (moved).

What you can try (try... try! Experiment first) is to use the DOS 'attrib' command to set the existing files to be read-only. Then copy the files over with the /y switch - it shouldn't overwrite the existing read-only files.

Hi all
I update it to use xcopy now. now it has param /y and /e to copy all the directory and subdirectory

Code:

---

xcopy C:\test1\*.* D:\test2\*.* /y /e

---

I plan to put this batch file into task scheduler, so I will have a daily copy of my files..

thanks in advance

Or maybe another idea, I can just delete the file that has already been copied. so then I will only copy the latest file ..

the file name is incremental by today's date

eg:
test 04-11-2008.zip
test 04-12-2008.zip
test 04-13-2008.zip

so if I delete the file after copying I will not overwrite anything right?

thank for moving the post .

there is an xcopy parameter for this. for a list of xcopy commands, type this at the command prompt:

Code:

---

xcopy /?

The correct methods are one of two ways: either copy only files with the archive bit set, or copy files newer than a certain date. xcopy can do either.
