Windows Live SkyDrive (initially Windows Live Folders) is part of Microsoft's Windows Live range of online services. SkyDrive is a file storage and sharing service that allows users to upload files to the computing cloud, then access them from a web browser. It uses Windows Live ID to control access to the user's files, allowing them to keep the files private, share with contacts, or make the files public. Publicly-shared files do not require a Windows Live ID to access.
The service currently offers 25 GB of free personal storage, with individual files limited to 50 MB.[1] Optionally, an ActiveX-based tool can be installed to allow drag-and-drop uploading from Windows Explorer. Up to five files can be uploaded each time if the tool has not been installed.
Windows Live SkyDrive（最初稱為Windows Live Folders）是微軟所推出的Windows Live服務之一部分。SkyDrive允許使用者上傳他們的檔案到網路伺服器上，並且透過網路瀏覽器來瀏覽那些檔案。另外，SkyDrive並透過Windows Live ID來限制不同的使用者所能夠存取的檔案，允許使用者決定是否將檔案與公眾分享，或是限於連絡清單上的人才能存取，亦或是將檔案設為只有自己才能存取。而對所有人公開的檔案將不需要Windows Live ID 即可讀取。
