Create virtual device that emulates physical storage. Present any data to end-user or applications as files and folders of a local virtual disk. The data may be of any type, such as database records, email messages, etc., located in one place or distributed over several storages including cloud storages. Callback File System provides all functionalities expected from a full-fledged file system.
Hide real data location from an end-user
Callback Files System gives you access to any data stored locally or at a remote location as if they are files on a local disk. The real location of data can be hidden from an end-user or application. With Callback File System you can create and apply a permission schema specifying what application or users can access, view or modify your data.
Do not replicate - modify remote data on-the-fly
Modify data being read from or written to the virtual file system. Such modifications are completely transparent for authorized end-users or applications. Both read and write operations are carried out on-the-fly transparently and efficiently.
Control access to the data
As all file requests go through your code, you have flexibility and power to check, what applications and what users perform the operations on your virtual disk, and optionally deny such operations.
Apply NTFS security to non-file data
Expose Callback File System virtual disk to the user by assigning it a drive letter or keep it hidden. Be in complete control over what applications or users may access data. Support all NTFS security functions for files and directories stored within Callback File System.
Port FUSE-based applications
Quickly port Linux, FreeBSD or MacOS X applications based on FUSE file system to Windows platform.
Rely on supported and growing solutions
Unlike unsupported amateur and hobbyist code Callback File System product is a solution which is actively maintained, developed and supported by highly-skilled professionals with extensive experience in low-level and system programming.
Technical Specification
Description
Callback File System - virtual file system SDK for Windows - technical description
Callback File System is a software component (library) for presenting various data as files and directories of a local virtual disk. Regardless of where the actual data are kept: in files, in database records, memory, or elsewhere - they will be treated as if they were parts of a single file system.
Callback File System consists of the system-level driver and user-mode API.
Driver
File System driver creates a virtual device with application-provided file system and 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 CallbackDisk, the driver of Callback File System provides a functionality to create not just your virtual disks, but your own file systems. The driver provides a callback mechanism, which lets you keep your files and file systems wherever you want (i.e. on remote computer, in memory or database tables etc.).
User-mode API
User-mode API is simple and introduces about ten functions, specific to driver management and storage mounting operations. Also the API includes about 20 callback functions (events) which your application must handle to effectively represent a full-featured file system.
The API is used for driver and storage manipulation and for security operations. All file operations can be performed using system file management API or framework-specific classes.
User-mode APIs are provided for .NET, VCL, Java and C++.
Security Features
Callback File System supports various security features. First of all, you can expose the virtual disk to the user by assigning it a drive letter, or you can keep the virtual disk hidden from user's eye (when no drive letter is assigned). Next, Callback File System lets you control what applications or users access the data. Finally, you can support NTFS security functions for files and directories stored within Callback File System.
