diff. In computing, the utility diff is a data comparison tool that computes and displays the differences between the contents of files. Unlike edit distance notions used for other purposes, diff is line-oriented rather than character-oriented, but it is like Levenshtein distance in that it tries to determine the smallest set of deletions and ...
A "diff" file comparison tool is a vital time and labor-saving utility, because it aids in accomplishing tedious comparisons. Thus, it is a vital part of demanding comparison processes employed by individuals, academics, legal arena, forensics field, and other professional endeavors — to identify sometimes hard-to-spot differences needed for ...
The software can display just the differences, the differences with a variable amount of context on either side or the whole marked-up text. The website supports the use of SSL ("https") so confidential text can be compared. The algorithm used by Diff-Text is used by Selection Diff Tool, which is an app for Microsoft Word and Excel 2013.

Rarely is there a warning before corruption occurs, this can make recovery difficult or impossible. Often, the problem is only apparent the next time someone tries to open a file.
The Levenshtein distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other. It is named after Soviet mathematician Vladimir Levenshtein, who defined the metric in 1965. [1] Levenshtein distance may also be referred to as edit distance, although ...
Plain text. Text file with portion of The Human Side of Animals by Royal Dixon, displayed by the command cat in an xterm window. In computing, plain text is a loose term for data (e.g. file contents) that represent only characters of readable material but not its graphical representation nor other objects (floating-point numbers, images, etc.).
File Compare. In computing, fc (F ile C ompare) is a command-line program in DOS, IBM OS/2 and Microsoft Windows operating systems, that compares multiple files and outputs the differences between them. [2][3] It is similar to the Unix commands comm, cmp and diff.
