Hi, I was wondering if anyone knows of any database or list of checksums for Microsoft files. I realize System File Checker (SFC) provides some of the functionality that I'm looking for, but I don't like SFC 5.1 and the SFC that comes with Windows 98 doesn't have premade databases for newer files. SFC 5.1 problems: - Can't recover files from MSDN's multi-install CD - Doesn't show why it wants to recover files - Doesn't show which files it wants to recover - Seems to rely on a dll cache Useful features: - Seems to support new files automatically (signed files?) - Allows users to recover files from original installation media Win 98's SFC problems: - Only supports one file version at a time - Relies on users knowing that new (anything not in the baseline) files are valid - No baseline databases beyond the originals from the CD's Useful features: - Allows users to recover files from original installation media - Shows users why it thinks a file is invalid - Shows information about the expected file and the given file (CRC?, Version, Date...) ... Basically, I want to be able to have a database of valid MS (and wine) file information to: - Detect corrupted files (viruses, file system damage...) - Allow easy recovery of corrupted files - Detect unofficial updates - Detect that a file update is available (security, new release...) - Create a list of non operating system files for backup ... Any suggestions/pointers are appreciated. Drew Daniels
