File comparison is an important, and integral process of file synchronization and backup. In backup methodologies, the issue of data corruption is important. 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.

License compatibility is a legal framework that allows for pieces of software with different software licenses to be distributed together. The need for such a framework arises because the different licenses can contain contradictory requirements, rendering it impossible to legally combine source code from separately-licensed software in order to create and publish a new program.

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 insertions to create one file from the other.
