CBFS® Direct

Instant control over process creation and termination in Windows and .NET applications


If you create software that needs direct access to the files or partitions of your disks (including hard drives and flash disks), you have probably faced the restrictions imposed by Windows Vista and later versions of Windows (up to Windows 10). Windows Vista and later don't allow you to access the disks from user-mode processes at all. Windows XP prevents you from using raw access to disks if the application is run under a restricted (non-administrative) account. All systems won't let you open the file if it's exclusively opened by another application or if security settings (permissions) don't let you.

CBFS Direct effectively solves this problem by providing a kernel-mode driver for use with your applications. Using this driver, you can read and write the data from/to the disk or opened files without any restrictions. Also, you can delete a locked or in other way inaccessible file. All you need to do is add two extra function calls to your application.

Access CBFS Direct Data in Windows XP, 7, 8.x, and 10

Enable your application to access the hard disk directly. Disk sectors can be read or written from user-mode processes, thus going around direct access ban imposed by the operating system.

Ignore File Locking and Security Restrictions

CBFS Direct allows access to files that are already opened or have restricted access security setting. This significantly simplifies implementation of backup application.

Read or Write Disk Sector by Sector

The ability to write and read disks sector by sector without operating-system-imposed restrictions comes in handy for development of data recovery, undelete, and forensic applications.
