I am glad you mentioned that.
To simplify the process of transferring and sharing files, I have a simple more efficient recommendation for you.
Click the link below and download for free this file sharing application called Dropbox.Download and Install Dropbox
(for Mac and PC)
I am suggesting this to you, because like you I have several Macs and a PC laptop that I must share files with, and do so everyday.
I have tried the standard file sharing between my PC and Macs with variable results.
But with Dropbox, it so simple to install, works with both Macs and PCs and literally keeps track of all files and folders between your computers with ease.
What's even better, is Dropbox comes with a notification software it installs on your computers called Growl, which is great because as soon as you make any transfer of files from one computer, say your Macbook Air for example, a notification box will appear on your laptop and desktop PC with Dropbox installed, indicating that addition of the file from your Mac.
I am not trying to be too impartial, but I have to be honest with you, it is one of the easiest apps for file sharing I have ever used for a mixed network of Macs and PCs.
Finally, a Dropbox account allows you to use 1 email address of your choice and uses that email to link that dropbox account to each computer you set up Dropbox with. It also comes with a free Basic 2GB Dropbox account, that can be upgraded to 50 GB up to 100 GB for a very inexpensive monthly fee ($9.99-19.99).
So I would make this recommendation, only because I believe it will work as well for you as it has for me, as we are both cross-platform users.
