dos file synchronization?

the dos command 'xcopy' can be used to to this.

for all the options of xcopy, type this at the command prompt:

xcopy /?

specifically to do what i think you're after, the command would look something like this:

xcopy c:\dir1\*.* c:\dir2\*.* /d:08-31-06

the above command should copy all files in dir1 created after 31st august 2006 into dir2.

if instead you only want to copy *newer* files you can simply do this:

xcopy c:\dir1\*.* c:\dir2\*.* /d

one of the advantages to xcopy over the standard copy command is that xcopy can copy subdirectories/folders too.

you will obviously need to test my examples above, but they should be more or less correct :)
