Currently we are offering source code of the following Windows kernel drivers. These are Windows kernel mode drivers which require the WDK (Windows Driver Kit) to be compiled.

Undeluxe minifilter driver source

This is a minifilter file system filter driver which captures deleted files to a recycle bin of your choice. It intercepts file system requests used for deleting files. It can coexist with the Explorer recycle bin. Unlike the standard Windows recycle bin, which is purely an Explorer concept implemented in usermode, this driver captures files deleted by any application.

The biggest challenge in developing this driver is the ability to handle subsequent delete and "undelete" requests. An application can issue multiple IRP_MJ_SET_INFORMATION / FileDispositionInformation requests with DeleteFile flag set to TRUE or FALSE. Explorer makes use of this technique because it first wants to find out if a delete operation will succeed before moving it to the (standard WIndows) recycle bin.

Undelex can be activated on both local and remote drives. It offers filtering capabilities so only files of your choice will be protected. It works on all versions of Windows which have the filter manager installed (on Windows XP Service Pack 2 is required). It compiles and runs on both x86 and x64 editions of Windows.
