Start-PsFCIV -Path C:\tmp -Recurse -Online -HashAlgorithm SHA1, SHA256, SHA384 Start-PsFCIV -Path C:\tmp -XML DB.XML -Show Ok, BadĬhecks all files in C:\tmp folder using SHA1 algorithm and shows filenames that match Ok or Bad category. The 'Delete' action can be appended to delete all bad files. Start-PsFCIV -Path C:\tmp -XML DB.XML -HashAlgorithm SHA256 -Action RenameĬhecks all files in C:\tmp folder using SHA256 algorithm and renames files with Length, LastWriteTime or hash mismatch by adding. Existing files are not checked for integrity consistence. Rebuilds DB file, by removing all unused entries (when an entry exists, but the file does not exist) from the XML file and add all new files that has no records in the XML file using SHA1 algorithm.

Start-PsFCIV -Path C:\tmp -Include *.txt -XML DB.XML -HashAlgorithm SHA512Ĭhecks all TXT files in C:\tmp folder by using SHA512 hash algorithm. Start-PsFCIV -Path C:\tmp -XML DB.XML -HashAlgorithm SHA1, SHA256, SHA512 -RecurseĬhecks all files in C:\tmp folder and subfolders by using SHA1, SHA256 and SHA512 algorithms. To completely remove module from the system, uninstall installation package: Uninstall-Module PsFCIV Examples Start-PsFCIV -Path C:\tmp -XML DB.XMLĬhecks all files in C:\tmp folder by using SHA1 hash algorithm and compares them with information stored in the DB.XML database. You may re-load it by using Import-Module command. However this command just unload module from a current session. If you wish to remove module from current PowerShell session run the following command: Remove-Module PsFCIV

This tool is distributed for free via source code on GitHub or binary download.Online - performs one-time hash calculation without creating a database file.Rebuild - adds new files to database and removes no longer existing files from database.FCIV - migrates FCIV database to PsFCIV format.Check - checks file share against database for integrity.New - creates a new XML database for file share.PsFCIV includes the following working modes:.Adds custom actions for bad (tampered) files: rename or delete file.Multiple hashes can be calculated for every file The hash algorithms available are MD5, SHA1 and SHA2 algorithm family.The utility can hash single files, folders, or recursively, large folder structures.Include or exclude sub-folders, choose algorithms, and direct output.PsFCIV is two-way compatible with FCIV database format, thus transition from FCIV doesn't require any efforts.

PsFCIV is a PowerShell-native opensource implementation of Microsoft-discontinued File Checksum Integrity Verifier (FCIV).
