Comparing File Fingerprints

Comparing File Fingerprints :

Fingerprint compares the data stored in two fingerprint csv files. The result is a csv File with all changes between the two fingerprints.

A File will be considered as "CHANGED" if one of the following properties has been changed : size, creation date, modified date, or the data (hash) of the file. A change of the last access date is not considered as a change.

fp.exe files_diff --fp1=<filename> --fp2=<filename> --f_output=<filename> [--batchmode]

If You do not pass any commandline parameter, fp_files will ask You for the name of the two fingerprints to compare (e.g. c:\fingerprints\fp_files_1.csv, c:\fingerprints\fp_files_2.csv) and the location of the results (e.g. c:\fingerprints\diff_fp_files_1-2.csv)

Commandline Parameters:

fp.exe --version           # show the version
fp.exe --help              # show the help
fp.exe <command> --help    # show the help for a specific command

fp.exe files_diff [arguments and flags]
  --fp1=<filename>         # the fingerprint #1, e.g. c:\fingerprints\fp_files_1.csv
  --fp2=<filename>         # the fingerprint #2, e.g. c:\fingerprints\fp_files_2.csv
  --f_output=<filename>    # the resultfile, e.g. c:\fingerprint\fp_files_diff_1-2.csv
                           # missing directories will be created, c:\fingerprint\fp_files_diff_1-2.log will be created
  --batchmode              # do not ask for missing or wrong parameters, but exit

The Result :

the result is a csv file what can be opened with excel or Your texteditor. the csv files might look like this :

c:\fingerprints\fp_files_1.csv :
