Windows: If you're looking for tighter integration between SkyDrive and your regular file storage, SkyDrive Explorer, as its name would imply, integrates Microsoft SkyDrive into Windows.
Once installed you won't find much flash to SkyDrive Explorer, it simply does what it promises. Provide your login credentials for your SkyDrive account and the drive that appears in My Computer — seen above — is linked to your online storage. You can interact with it like any other drive.
If you need to access a wider variety of online storage you'll want to check out previously reviewed Gladinet which can connect to SkyDrive along with other storage sites like Amazon S3.
