File checksum integrity verifier12/25/2023 ![]() Here’s a few commands that can be used to verify the hash values for the files in the Windows directory and in all sub-directories. -xml db: Specify database format and name.Īs FCIV supports storing of hashes of various files in database in XML format, thus it can be used to verify the integrity of files over time.-md5, -sha1, or -both: Specify hash type.-bp: Remove the base path from the path name of each entry.(By default, FCIV stores the full path name.) -exc file: Do not compute these directories.The dir parameter has the following options: -add file | dir: Compute the hash and send it to an output device (default screen).Generally, fciv.exe has the following syntax: To display the SHA-1 hash of a file, use the folling command: To display the MD5 hash of a file, type the following command at a command prompt: To use FCIV to calculate and generate MD5 or SHA-1 hash is easy. ![]() If user doesn’t specify the path to FCIV in environment variable, then the full path to fciv.exe has to be typed each time the command is run. Click on Environment Variables button, and the path system variable can be edited to include the path to folder where File Checksum Integrity Verifier is installed. Go to System Properties, and then Advanced tab. The path environment variable can also be set in Control Panel. Alternatively, just install FCIV to %SystemDrive%\Windows\System32 folder. For example, if FCIV is installed in C:\FCIV folder, type set path=%path% c:\fciv to add it to the system path in a command shell. Use the “set path” command to add a new folder to the path environment variable. Those who prefer a GUI user interface, there are several other file hash checksum calculators or tools available.Īfter downloading and installing FCIV, user will need to add a path reference to the directory when FCIV is installed so that FCIV can be called from anywhere else. ![]() FCIV utility runs on Microsoft Windows 2000, Windows XP, Windows Vista, Windows 7, Windows Server 2003, Windows Server 2008 and Windows Server 2008 R2.įor user who interested to uses File Checksum Integrity Verifier can download the FCIV setup installer (KB841290) from Microsoft Download Center with direct download link: windows-kb841290-x86-enu.exe.Can run a verification of the file system files against the XML database to determine which files have been modified.FCIV can compare hash values to make sure that the files have not been changed.Can store hash values in database for a file with or without the full path of the file. ![]() Supplies an exception list to specify files or directories to hash.Can recursively generate hash values for all files in a directory and in all subdirectories (for example, fciv.exe c:\ -r).Can output hash values to the console or store the hash value and file name in an XML file.Supports MD5 or SHA1 hash algorithms (default is MD5).The MD5 and SHA-1 checksum values generated by FCIV can be displayed on the screen to compare against known good value or saved in an XML file database for later use and verification.įeatures of File Checksum Integrity Verifier (FCIV): The File Checksum Integrity Verifier (FCIV) is a free command-prompt utility from Microsoft that computes and verifies cryptographic hash values of files with support for MD5 or SHA-1 cryptographic hash values.
