Technical Specification

Description

CallbackDisk allows developers to create virtual disk the easiest possible way. Proper virtual disk will appear after implementation of several callback functions. This disk can be formatted to FAT, NTFS, SolFS or any other file system.

CallbackDisk consists of the system-level driver and user-mode API.

Driver

Virtual disk driver creates a virtual storage device, which emulates a physical storage.
The driver works on the system level and turns a storage into a "real" disk device with its own file system. The "real disk device" is accessible in read-only and/or read-write mode by any application which uses system file management API.

The driver lets you make the mounted disk visible to the user or hide it from the user.
Unlike SolFS Driver Edition, the driver doesn't read or write the data from/to the physical location. Instead, the driver provides a callback mechanism, which lets you keep your data storage wherever you want (i.e. on remote computer, in memory or database record etc.).

User-mode API

User-mode API is simple and introduces just about ten functions, specific to driver management and storage mounting operations.
The API is needed only for driver and storage manipulation. All file operations can be performed using system file management API or framework-specific classes.
