Copy from one location to another using batch script based on modified date and also newly added files in source
How to copy files which are modified and the new ones that are added in the source location to the target location using a batch script? The existing files that are already present in the target should not be copied again, only the newly added ones and the modified ones. Kindly help.
Copy from one location to another using batch script based on modified date and also newly added files in source
Okay, so you're using batch in Windows and the XCOPY command. You should be fine to use the native Windows Robocopy command rather than XCOPY, which is a much more robust way to complete your task than a batch script using FOR loops with XCOPY and date time stamp substitution checking, etc. That's possible too but with some gotchas but it's a bit more complex than the simple and clearer method using the Windows native ROBOCOPY commands from a batch script or command line.
If you're building something new, it'd be best to use Robocopy instead of XCOPY as XCOPY is a deprecated command intended to be replaced by Robocopy specifically per Microsoft as of Windows Vista (and newer OSes) I believe.
Assumption Per Your Question
The assumption I'm going to make here is that you tried this using some XCOPY commands and couldn't get it to work for your need so I'm going to assume you did that work and now asking for help, but if you have any example of what you tried (and didn't work), go ahead and update your question with that to satisfy this concern for others.
I'm not recreating the wheel here and making a sensible suggestion based on your question and good judgement for what you've disclosed. You will still need to do some work, read the syntax of Robocopy, plug in your variables and/or further options and switches, and do some testing on your side confirming everything works as expected in case you need further adjustments.
Robocopy Script
(See Script Notes below for options I used in this example and also be sure to change the sourcedir and targetdir variable paths where you need those set. Be sure to test from a test location as well just to be thorough and to confirm yourself before using for production purposes.)
@ECHO ON
SETLOCAL
SET SourceDir=C:\SourcePath
SET TargetDir=C:\TargetPath
SET LogFile=C:\LogPath\Logfile.txt
ROBOCOPY "%SourceDir%" "%TargetDir%" *.* /PURGE /S /NP /R:5 /LOG+:%LogFile% /TS /FP
GOTO EOF
Script Notes
I used these options in my example but see below how to see all options to further suit your particalar needs.
/S :: copy Subdirectories, but not empty ones.
/PURGE :: delete dest files/dirs that no longer exist in source.
/NP :: No Progress - don't display % copied.
/R:n :: number of Retries on failed copies: default 1 million.
/LOG+:file :: output status to LOG file (append to existing log).
/TS :: include source file Time Stamps in the output.
/FP :: include Full Pathname of files in the output.
