Recomended that you have a NTFS file format...
Turn on the Advance file shareing...
now just share the Folder with stirct rule that only an Admin or rather ur user can access it...
therefore all other users wont be able to access...
Here a short description...
Go to Folder Option, and check off the Simple File Share... !!!

Now just right click on a folder which u would like to share and click properties, go to sharing TAB,
now at the permission windows, remove the default Every One, and add either admin user group or just your user... !!

this will make sure that only ur user gets the access to that folder..
By the way, you have asked the same question once more...
