FileVerifier++ is a Win32 application for verifying the integrity of files. FileVerifier supports various algorithms by means of dynamically loadable hash libraries. It is a pure Win32 C++ application and doesn´t have any dependencies other than what comes with Windows. Permanent installation is not required and may be burned to a CD or used from a flash drive.

The FileVerifier++ Shell Extension is a useful addition to FileVerifier++. The extension adds a context-menu handler to Windows Explorer that allows one to hash a set of files and/or directories. The menu allows one to choose between the default hash algorithm and each installed algorithm.

Features:

• Can load and save results to and from various formats.
• Hash algorithms can be added through the DLL interface.
• Hash verification. Can load hash results and compare to what is actually on your disk.
• Color coding of validity states
• Verification considers file size, file attributes, and modification date to be significant.
• Drag and drop support.
• Recursive directory processing.
• Calculates hashes on strings.
• Search and grep using regular expressions.
• Selective verification.
• Unicode support (recognizes Unicode file names and writes results encoded in UTF-8 (without BOM))
• Supports Windows XP Visual Styles
• Shell Integration (Shell extension).
• Can be installed using installer or without.

System Requirements:

• Windows 2000 IA32
• Windows XP Home/Professional IA32
• Windows Server 2003 IA32

What's New in version 0.6.3.5830:

• A situation where the program would crash upon recalculating or verifying a list where a significant number of files are skipped initially has been fixed.
• A situation where the program will crash upon writing lists with entries with dates prior to 1/1/1970 has been fixed. Any dates prior to this will be set to 1/1/1970. This restriction will be lifted in future versions.
• A workaround for a condition causing a brief delay in the program exit on certain systems has been applied.
