Comparison and Match Tool Utilities
The Digital Age has certainly come upon us, and the use of computers has invaded almost every aspect of human endeavor. While casual users may find themselves working on a word processor or spreadsheet program once in a while, there are also many heavy users that find it necessary to work with multiple files at once. For example, someone responsible for even just a part of an organization’s information would need to deal with many different documents at a time. A comparison or match tool can come in quite handy to help lessen the tedium in organizing and keeping track of large numbers of documents.
These comparison utilities, as their name implies, can process and look at two files, documents, or even directories side by side. So, they aim to help users spot the differences between two versions of the same file, for instance. In their most basic forms, they can still make the life of an analyst much easier by automating the tiresome process of manually looking through two files to check their differences. Hence, they can be used also as a secondary check as to whether two files contain identical parts. Just this feature alone can save a lot of time. Many of these utilities would allow direct editing from within the comparison panes themselves, streamlining the entire process.
More sophisticated comparison tools would offer more advanced features to take advantage of. These would include being able to display in more detail how exactly parts of one file differ from the corresponding parts of the other file. Color coding, easier navigation through the differing parts, and so on all contribute to making the entire experience more convenient and user friendly. Instead of simply highlighting differences, many of these tools would allow the user to customize how these are displayed.
Apart from display customization, some of these comparison tools would also allow for customizable queries. That is, instead of simply searching the entirety of each file and comparing the contents with one another, the user could select to compare specific parts of each file. This may be done by simple selection, or sometimes through the use of regular expressions to indicate parts to either skip over or process. This allows for a great deal of flexibility, since the files to be compared do not need to be identical except for a few changes. Instead, even just portions of files may be processed using these tools with good results.
File merging is another handy feature to have, and like it says, it involves combining two different versions of the same file. Merging involves scanning the changes and determining which version has the desired content, usually by considering the relative age of each file. This process has to be quite flexible and intuitive to the user so that mistakes may be avoided. Fortunately, a lot of the match tool options available can indeed handle file merging gracefully and without much difficulty. With these functionalities and more, a lot of these tools will certainly be useful to casual and power users alike.
