[General] automatic CRC comparison to find changed files |
|
It would be a great way to see if a virus or something else modified files or to see what changes when you install an update. Obviously I would like GUI for this, but Here is what I would want from the command-line.
cdcheck /exclude[pathname] /log[pathname] /verify[input paths seperated by commas] [/u]
This would verify the CRC for all files in the input paths and if the /exclude[pathname] were specified skip files or directories listed in the supplied exclude file. The /u would cause cdcheck to automaticly update a CRC in the CRC list if it had changed. The /log[pathname] would cause cdcheck to log the results in a log file.
An example command would be
cdcheck /exclude /log /verify[c:,e:] /u
Would use the default exclude file and log file in the cdcheck folder, verify the CRC's on drives c: and e: (sub directories would be included, but you could optionally suppress this if you wanted) and update the CRC file with any CRC's that changed.
An exclude file might look like the following
*.ini ; skip all .ini files
c:\testfile ; skip c:\testfile
c:\*.* ; skip all files in the root of c:\
c:\ ; skip all files on drive c
The log file might look something like this
cdcheck started checking drives c:,e: at date/time
file c:\testfile changed (updated to new CRC)
processed files number of files
processed bytes number of bytes
file validation completed at date/time
This log would assume that /u was used otherwise the c:\testfile would not show that it's CRC had been updated in the log.
If this functionality was added then one could create a scheduled task to run this each day and then look at the report to see any changed files and restore them from backup if necessary. The /u would automaticly update the CRC to prevent from having to run it again to update the CRC. If the CRC gets updated, but the file was incorrectly changed then it wouldn't matter as once you restored the original file the CRC would get restored with the next daily run. In fact you could store the previous CRC and if the file was restored then note that the previous CRC was once again valid in the next run if you wished.

I have just discovered this utility and think it is fantastic. I also really think it would be an even more useful utility with these suggested features. It is exactly what I was searchibg for.
The win98se system file checker is pathetic

Thnis is a newbie question but what is a CRC list?

CRC list is a list of files with their CRC values. For more information on CRC I suggest you read:
