I want to transfer files from xp to win7 via LAN

I want to transfer files from xp to win7 via LAN. however, i want the files to go to a specific partition that i just created for these files. Im unsure how to select the proper partition. there is nothing on the new partition, no OS, i just want to use it as storage.
I have a 1tb hdd in the computer the files are to be transfered to. when i did a clean install of win7, i created a 100gb partition to use as my primary, (with my OS and basically everything), leaving the other 900gb unallocated space. i just created a 24gb partition to use to back up files from another computer.
in command prompt as administrator, in diskpart, i selected the new volume, but im not seeing a new drive designation for the new partition in which this volume is supposed to be located.
i also did not choose a label for the new partition, such as C; D; E;...., so that does not help with trying to locate this partition in windows explorer.
im lost and dont want to make any stupid mistakes.
it seems like this should be really easy to do.
am i missing something?

right click my computer, choose management then choose the disk manager, you should find your new partition there, and be able to assign it a drive letter if the system hasn't already.

Assuming you have a router all you need to do is activate sharing on the appropriate folders and do a copy paste. It will more than likely be easier to do it from the win 7 machine as the win xp machine will ask for the admin account and password information.

ok, im on the win 7 machine, computer/computer management/disk management/format. i have labeled the volume and placed it under NTFS file system.
for the allocation unit size i want the entire 24576mb to be formatted but it isnt an option. would that be the default option? other than that i have the quick format box checked but have not pressed ok to apply changes yet

as long as the target size is relatively close, it rarely does give you exactly what you want. I wouldn't be concerned if you are working with blank disc space, the only reason to be concerned would be if it were trying to format a larger block than you had freed.

ok, i formatted the new partition.
so now i just copy and paste the files to be transfered? im unfamiliar with windows easy transfer, but i was looking into that.
at the moment i dont have both computers, so i cant transfer yet, but thanks for your help. what do you think about WET?

cool. problem solved. thanks for your help Maguscreed. much appreciated.

thanks for the link WHS. I added those options to the context menu. that should make alot of things easier.

Now how do find my new partition to paste the files into?
in disk management the partition is listed as a healthy primary partition. but in windows explorer, in the left pane, under computer it only lists Local disk (C:). the new partiton is (N:), but i cant find it when looking for the destination for the files. in short, i can transfer the files, but not to the new partition.

You use Disk Mgmt only to create and format the partition.

After that use Explorer by clicking Computer to rightclick share the drive and its contents with Homegroup. If not Homegroup, then rightlick on partition, on Properties tab under Security>Add "everyone" should cover it.

Do this for the folder you're copying from as well.
