bat file or ps file creation

basically here is the logic.

there are 4 local folders that have data that need to transfer to shares.


on the local machine there are files in 4 folders.

e:\map\drawer
e:\map\symbol
e:\map\points
e:\map\lines



there are 4 shares that user has access to but they are not mapped.
do i have to map them.  He does have permission to them but i would rather not map them.
if mapping is better part then i can do that.


the shares are


\\host1\drawer
\\host1\symbol
\\host1\points
\\host1\lines

I need all contents of the drawer local folder to replace all contents of the drawer shared folder.  There should be 4 files with the exact same name.  I need it to leave files in the destination folder if there is a file in the destination folder  with a different name(the destination folder has a file that the source folder does not have.)

I would rather do a batch at this time.
