Panda is a virtual file system that allows the user to have one or more virtual disks with its own directory tree and files.

Panda consists of a library module, a graphical browser and a disk synchronization server.

The library module (the "core") handles disk file input/output and lets the user navigate through the file system's directory tree and move files and folders to and from other file systems.

The core library consists of three layers: the file system API, the block API and the IO layer.

The file system API is what clients of the Panda library use. It models the virtual disk and the file system on that disk on a logical level. The main prupose of this API is to hide the complexity of the underlying file system implementation, essentially a facade pattern.

The implementation of the file system API is based on the block API, an abstract view of blocks ("clusters","nodes") on the virtual disk. Strictly separating the IO layer from the block API allows the creation of mock and debugging implementations of the block storage for testing.

The IO layer, finally, is used to implement the block API and handles the actual storage and retrieval of data on the host file system.
