At the risk of sounding rude – when you submit a question, you should provide as much background as necessary.
However, I’ll make the following assumptions:
1) The folder on the LAN drive is always mapped to the same drive letter on the local system
2) The folder location doesn’t change
3) The folder name doesn’t change
Create a text file named copylan.bat containing your version of the following:
copy /y l:so-and-so c:so-and-so
The /y prevents you from being prompted in case the same files already exist. This works if so-and-so are directory names OR file names.
For more info on this – open a command window on your system and type HELP COPY <Enter>
Then either put the batch file name into the AT utility, or for on-demand, copy a shortcut to the batch file to your desktop, or other folder, or put a shortcut into the Startup folder so that the copy is performed on login.
Hope that helps,
