"Pros and Cons"
Pros
This product is good for identifying LINES that are different between two files.
Cons
* This product is poor at identifying differences WITHIN LINES. (major limitation)
* The comparison results window does not scroll for long lines. (minor limitation)Summary
This product does a good job of identifying which lines in a file are different. Unfortunately, it is poor at identifying differences in fields WITHIN lines.
After getting the main Comparison Results window which lists the lines with differences, double-click on a line in question to see the differences within the line. An editor window opens. The left-hand portion of the line that is the same is green. The right-hand portion of the line that is different is red. The difficulty is that once a difference is encountered that changes the line length, everything past that change is marked as red. For example, if you compare a data file where one record has the name "JOHN" in it and the corresponding record has the name "JOHNNY" in it, everything after "JOHN" in both records is flagged as different, even though only the name field has changed. Hence, only the first changed field within a line is identified; all subsequent fields are red flagged whether or not there are differences.
While this program would work well for comparing files with short record lengths (such structured SQL scripts), it has limited usefulness in identifying specific field differences in long record lengths (such as .csv or .tab delimited files).
