Psionandy is correct for a typical home wireless network. It would merely be a matter of creating a mapped drive in Resco or "new server" with Total Commander CE. Resco is my favorite, but Total Commander, while not as pretty, has the virtue of being free and equally powerful in many ways. Connecting to either should be as simple as entering the proper username/password with permission to access your pc's shares. One minor caveat: The device may occasionally try to enumerate the shares and file structure of the remote drive with certain apps, and it may seem that the device is momentarily frozen when in fact it's simply reading the remote shares. This hasn't been a problem for me, but I've heard of a few others experiencing this.
If you're unfamilar with either app,
this is a nice quick review of Total Commander CE's features, and
this has a product description for Resco and links to reviews.
