Callback File System will let you create virtual file systems and disks which meet your requirements, and give you full control over your data.

With Callback File System you can create your own file system within your application and expose this file system to Windows as a virtual disk.
Callback File System is an SDK (Software Development Kit) which opens the way to create your own filesystems with little or no efforts.
Callback File System includes ready-to-deploy kernel-mode device driver and a user-mode API, which is used by your application. The driver creates a virtual disk with your filesystem and provide system-wide access to the disk.
The API lets you manage the driver and the virtual disk from any Windows or .NET application.
With Callback File System you can run your filesystem code in user mode, letting the driver to deal with complexities of the kernel mode.
Such approach lets you offer the remotely stored information for system-wide access.

Limitations:
· 60-day trial

What's New in This Release:
· Sporadically occurred BSOD during system shutdown.
· On some machines when the network mounting points are used Explorer stops automatic refreshing of view for changed files/directories.
· IOCTL requests sent to CallbackFS disks via network mounting points are always Initialize method now checks for driver being installed and throws exception when the driver is not installed.
· [VCL] In C++Builder the linker could not call GetModuleStatus due to its bug (pointer to structure made the linker not see the function in the library). Workaround added.
· The CBFS_SYMLINK_NETWORK_ALLOW_MAP_AS_DRIVE flag sometimes doesn't work with the CBFS_SYMLINK_NETWORK_READ_NETWORK_ACCESS and CBFS_SYMLINK_NETWORK_WRITE_NETWORK_ACCESS flags.
· A sporadically occurring deadlock in the CallbackFS driver fixed.
· InstallIcon and UninstallIcon functions in the Installer DLL got new ProductName parameter.
· [VCL] Added Delphi XE4 and C++Builder XE4 support
· Possibility of BSOD during file renaming when the CaseSensi...
