Create a batch file (.bat) and paste the below code:
robocopy \\192.168.0.30\sanjeebapp\data\in E:\sanjeebapp\data\in\ /mov /maxage:%DAYS%
Note: Change the source folder and destination folder as needed. /mov deletes the file from the source location . /maxage ignores the file which is older than DAYS. In this example, the files older than 7 days are not copied.
Remove /mov from the script if you do not want to delete files in the source folder.
