Unfortunately, SDExplorer do not work anymore on Windows 10, so I made an alternative for Windows here:

I have better experience with mounting the WebDAV address from SkyDrive Simple Viewer for WebDAV:
SkyDrive Simple Viewer for WebDAV

Note the following restrictions when working with mapped folders using SDExplorer:

• SDExplorer does not mount your SkyDrive account in its entirety: each root folder is mounted as a separate disk.
• SDExplorer supports mounting only SkyDrive folders whose contents type is "Documents"
• Large files (over 50 MB) are not supported within the mapped drive.
• Working with mounted disks is not fast.
• On some PCs with Windows XP installed, files are not copied correctly from the mounted drive.
• Some characters in filenames are converted by Microsoft's servers internally. For example, _ tranforms to ^_, & to ^0, ( to ^5, etc. You need to take it into account when you plan to use mapped drive for backup.

The most worthwhile option is to use such a mapped disk with third-party programs for data synchronization and backup utilities in background mode.

The access to the files and directories with the new service "Skydrive Explorer beta" is similar slow as with Gladinet Cloud Desktop ( http://alternativeto.net/desktop/gladinet-cloud-desktop/ ) , for my personal use too slow. You have a much faster access to the files in the cloud with DropBox: http://alternativeto.net/desktop/dropbox/ . Here you have a real synchronous copy of the remote files on the local computer. Because of this, access is exactly as fast as on the local computer. But the size limit of free online storage of Dropbox is only 2GB, of skydrive 25 GB. For purposes with very big files, for which a slower access is acceptable, Skydrive Explorer may be a very good application.
