Important
DigitalRune.Storages currently only provides read access to files! Full read/write access, as well as support for additional platforms, will be added in a future version.

The IStorage interface provides a common API to access files from different sources. The following implementations provide access to physical file systems on different platforms:

• FileSystemStorage - provides access to the file system of the operating system.
• TitleStorage - provides access to title storage on Xbox 360.
• (Not yet implemented) UserStorage - provides access to user storage on Xbox 360.
• (Not yet implemented) IsolatedStorage - provides access to isolated storage in Silverlight.
• (Not yet implemented) WindowsStorage - provides access to storage folders in Windows Store apps.

Some storages are built on top of other storages. For example:

• VfsStorage - maps existing storages into a virtual file system. Different storage devices and locations can be treated as one directory hierarchy.
• ZipStorage - provides access to files stored in a ZIP archive. The ZIP archive can be read from any of the existing storages.

Case-Sensitivity:
File retrieval is case-sensitive if the storage provider (e.g. the platform OS) is case-sensitive. It is recommended to assume case-sensitivity to ensure that applications can be ported to non-Windows platforms.

Directory Separator:
Storages accepts '\' and '/' as directory separators. Internally, paths are normalized to use '/'.

Possible Extensions:
The IStorage concept is highly extensible. Developers can provide custom IStorage implementations to add support for new platforms or manipulate existing storages. Here are just a few features that could be implemented on top of IStorage:

• Access control - A storage may wrap another storage and implement access control to restrict user access or filter certain files. For example, a "ReadOnlyStorage" may prevent write access to an existing location.
• Archives - Storages can be added to support other package formats, such as 7-Zip, BZIP2, PAK.
• Caching ("CachedStorage") - Files from another storage could be cached in memory for faster access.
• Cloud storage - A storage may access data in the cloud, such as OneDrive.
• Encryption ("EncryptedStorage") - Data could be encrypted and decrypted when accessing files in an existing storage.
• Mapping ("RedirectStorage") - Directories can transparently be mapped to different location.
• Redundancy ("MirroredStorage") - File access could be mirrored across different storages.
• Ad-hoc storage - Instead of accessing files on an existing devices or locations, files can be stored in custom data structures (DBs, BLOBs, ...).
