The following:

xcopy c:\Nos\*.*/s d:\Nos\"%Date%"\*.*/Y

works but it copies all the files in the directories and files that are not
updated are also copied.


Saw the following:
/D:m-d-y Copies files changed on or after the specified date.
If no date is given, copies only those files whose
source time is newer than the destination time

and have tried to incorporate it into the xcopy command above but have failed after MANY attempts and with many combinations.

Files that are not updated do not need to be copied.

I am new to ms dos.

Kindly help.

Thanks.
Hi Hu,

It seems to work for me, using Windows XP. In the example below, I only copy files updated since 1st July ("7-1-2007") to a "target" directory.

Code: [Select]D:\test> DIR
Volume in drive D is DATA
Volume SERIAL Number is 9842-52D0

Directory of D:\test

03/07/2007 10:17 <DIR> .
03/07/2007 10:17 <DIR> ..
03/07/2007 10:28 <DIR> target
03/07/2007 10:16 385 July.txt
26/06/2007 12:47 385 June.txt
2 FILE(s) 770 bytes
3 Dir(s) 89,285,689,344 bytes free


D:\test> XCOPY /D:7-1-2007 *.* target
D:July.txt
1 File(s) copied

D:\test>

Please can you paste & POST an example directory listing that you are trying to copy, together with the output generated by your XCOPY, and I will try to replicate/investigate on my PC.

Thanks,
JamesHi Hu,

I've had an additional thought. If you want to use the system variable "%DATE%" as the "XCOPY date", then you need to convert the date format from dd/mm/yyyy to mm-dd-yyyy.

To do this, use a batch file Similar to the one below. (I have named mine "backup.bat")

Code: [Select]for /F "delims=/ tokens=1-3" %%A in ('echo %%DATE%%') do XCOPY /F/I/D:%%B-%%A-%%C *.* %%B-%%A-%%C

Here is an example of this batch file being used on Windows XP:

Code: [Select]D:\test> DIR
Volume in drive D is DATA
Volume Serial Number is 9842-52D0

Directory of D:\test

03/07/2007 12:56 <DIR> .
03/07/2007 12:56 <DIR> ..
03/07/2007 12:50 100 backup.bat
03/07/2007 10:16 385 July.txt
26/06/2007 12:47 385 June.txt
3 File(s) 870 bytes
2 Dir(s) 89,292,156,928 bytes free


D:\test> BACKUP

D:\test>for /F "delims=/ tokens=1-3" %A in ('echo %DATE%') do XCOPY /F/I/D:%B-%A-%C *.* %B-%A-%C

D:\test>XCOPY /F/I/D:07-03-2007 *.* 07-03-2007
D:\test\backup.bat -> D:\test\07-03-2007\backup.bat
D:\test\July.txt -> D:\test\07-03-2007\July.txt
2 File(s) copied


D:\test> DIR 07-03-2007

Volume Serial Number is 9842-52D0

Directory of D:\test\07-03-2007

03/07/2007 12:56 <DIR> .

Hope that helps,
