Over the past couple of years, Apple has taken new interest in MobileMe. They have overhauled the service with refinements and new features. Our sales of MobileMe are skyrocketing. MobileMe’s easy options for syncing data between computers and iOS devices along with the “Find My iPhone” feature makes MobileMe worthwhile by itself.

From conversations with my friends, it seems that iDisk is one of MobileMe’s lesser known and used features. It’s one of the core MobileMe services that Apple has truly polished and improved over the past two years.

I really only use iDisk to share large files (up to 1GB) with vendors, clients and friends. If you haven’t tried doing this recently, you’ll be impressed how easy it is. With any modern web browser, simply log into your MobileMe account at Me.com. and select the iDisk icon (the one used at the top of this article).

Next, select the “Public” folder in the left hand pane. Click on the “up” facing arrow at the top of your web browser. A new “upload” window will open. Use this window to browse to the file you’d like to share (again, up to 1GB). After the file uploads, you’ll see options for sharing the file, including via email. Note that you can also password-protect confidential files.

The link to your public iDisk folder is always https://public.me.com/yourmobilemeusername. If you have MobileMe, take a look at your public folder, so you can see it as others see it.

You can set permissions so people can also upload files to your iDisk. This is a very easy way to request files that are too large to be emailed.

If you have files to share that are larger than 1GB, I recommend Dropbox (sync files of any size or type) and Droplr.
