Fuzzy matching
Fuzzy matching enables ExamDiff Pro to intelligently align lines that are similar but not identical. The options in this section control when fuzzy matching is activated and how selective it is.
  • Do not perform fuzzy matching
    Selecting this option always disables fuzzy matching.

  • Always perform fuzzy matching
    Selecting this option always enables fuzzy matching. This option is not recommended if you are comparing huge files, as it can potentially greatly slow down comparison.

  • Perform fuzzy matching only if both files are smaller than
    Selecting this option enables fuzzy matching only if the files compared are both smaller than the specified size (250KB by default).

  • Matching method
    Use this option to control how the matching of similar lines is performed. The default is Characters, and it suitable for most uses. Choose Words if your files have many distinguishable words.

  • Line similarity
    This option determines the percentage similarity that two lines must have in order to be aligned if fuzzy matching is turned on. Keep in mind that if a line has multiple potential matches within a diff block, the match will be selected that maximizes the total similarity of all the fuzzy matches in the block.

    Selecting 100% similarity effectively disables fuzzy matching.

    Selecting 0% similarity bypasses ExamDiff Pro's comparison algorithm and triggers line-by-line comparison, in which every line is matched to the line at the same position in the opposite file (i.e. line 50 in the first file will match with line 50 in the second file, ignoring their contents.) If fuzzy matching is only enabled for files below a size threshold but line-by-line comparison is enabled, line-by-line comparison will take effect even if the file size is larger than the set threshold.
Force text/binary comparison
  • Automatically detect text/binary files
    Allow ExamDiff Pro to determine whether the compared files are text or binary.

    • Always treat these files as text
      Files matching any name filter in this comma-separated set will always be treated as text files.

    • Always treat these files as binary
      Files matching any name filter in this comma-separated set will always be treated as binary files, unless they also match one of the filters in the Always treat these files as text set (text takes precedence over binary).

  • Treat all files as text
    Compare all files as text and show the results in text format.

  • Treat text files as binary
    Compare all files as binary and show the results in HEX format.
