Usage
FileHash is the command line tool. Open command prompt and start the FileHash tool with following parameters:
filehash <command> /<switch 1> /<switch N> <checkfile> <path to folder> <path to file> <pa?h with?wild*cards>
Commands
c Calculate hashes of files and folders provided and save them into a checkfile
v Compare checkfile contents with a path provided
l List checkfile contents to the console
Switches
/Help Display this help message, if no arguments provided, set by default
/NoLogo Don't print copyright logo
/Recursive Scan all subfolders in the provided folder
/Overwrite Overwrites the checkfile, if already exists
/MD2 Hash files with MD2 algorithm
/MD4 Hash files with MD4 algorithm
/MD5 Hash files with MD5 algorithm
/SHA1 Hash files with SHA1 algorithm
/SHA256 Hash files with SHA256 algorithm. If no other algorithms provided, set by default
/SHA384 Hash files with SHA384 algorithm
/SHA512 Hash files with SHA512 algorithm
/AlgoALL Hash files with ALL algorithms above
Path limitations
With c command, maximum 1024 paths to files and/or folders can be provided. Wildcards are supported
With v command, only one folder can be provided
With l command, only one checkfile can be provided
You should use double quotation marks (") if the path has spaces in it
Exit codes
0 Requested operation completed successfully
1 No files were found to hash, checkfile was not created
2 The user pressed CTRL+C or CTRL+BREAK to terminate the program
3 Check completed, but file(s) with wrong hash(es) found during the check
4 Initialization error occurred. There is not enough memory or disk space,
an invalid path to a checkfile entered or invalid syntax of the command line arguments
5 Disruption or inability to read, write, transfer or analyze data from/to the disk
Usage examples
hash all files and folders recursively inside the D:\backups\ folder with SHA1 and MD5 algorithms and save hashes into the backup.checkfile:
filehash c /Recursive /SHA1 /MD5 backup.checkfile D:\backups\
hash all files inside the D:\My Projects\Slam\ folder with the default SHA256 algorithm and save them to the project-slam.checkfile. don't hash files in subfolders:
filehash c project-slam.checkfile "D:\My Projects\Slam\"
hash files with .cab and .zip extensions inside the D:\reports\ folder with MD5 algorithm and save them to the reports-2023.checkfile. if the file exists, overwrite it:
filehash c /Overwrite /MD5 reports-2023.checkfile D:\reports\*.zip D:\reports\*.cab
list contents of the "books about art.checkfile" from the C:\Users\Public\Documents\ folder to the console:
filehash l "C:\Users\Public\Documents\books about art.checkfile"
compare contents of usb-flash-copy.checkfile with files on the E:\ drive:
filehash v E:\usb-flash-copy.checkfile E:\
.checkfile structure

Building
FileHash tool uses the Microsoft Visual Studio 2022 for its builds.
To build FileHash tool from source files with Microsoft Visual Studio, you can use either the graphical mode or the command-line mode. Here are the instructions for both methods:
Graphical mode:
Graphical mode
- Open Microsoft Visual Studio and select Open a project or solution from the start page or the File menu.
- Browse to the folder where the .sln file is located and select it. This will load the project in Microsoft Visual Studio.
- Select the configuration and platform for the project by using the drop-down menus on the toolbar. For example, you can choose Debug or Release for the configuration, and x86 or x64 for the platform.
- Build the project by clicking on the Build menu and selecting Build Solution. You can also use the keyboard shortcut Ctrl+Shift+B.
- Run the project by clicking on the Debug menu and selecting Start Debugging. You can also use the keyboard shortcut F5
Command-line mode:
Command-line mode
- Open a Developer Command Prompt for Microsoft Visual Studio. You can find it in the Start menu under Microsoft Visual Studio Tools.
- Navigate to the folder where the .sln file is located by using the cd command.
- Invoke the MSBuild tool to build the project. You can specify various options and flags for the tool. For example, the following command builds the project with the Release configuration and the x64 platform:
msbuild FileHash.sln /p:Configuration=Release /p:Platform=x64
Run your executable by typing its name in the command prompt. For example:
FileHash-exe-x86-64\FileHash /?
msbuild FileHash.sln /p:Configuration=Release /p:Platform=x64
- Run your executable by typing its name in the command prompt. For example:
FileHash-exe-x86-64\FileHash /?
Testing
To test FileHash start testing script FileHash-test-scripts\runall.ps1 and wait for it to finish.
