An edit conflict is a computer problem that may occur when multiple editors edit the same
file and cannot merge without losing part of their edits.
Description
The conflict occurs when an editor gets a copy of a shared document file, changes the copy, and attempts to save the changes to the original file, which has been altered by another editor after the copy was obtained.
Resolution
The simplest way to resolve an edit conflict is to ignore intervening edits and overwrite the current file. This may lead to a substantial loss of information, and alternative methods are often employed to resolve or prevent conflicts.
* Manual resolution, where the editor determines which version to retain and may manually incorporate edits into the current version of the file.
* Store
backup
In information technology, a backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event. The verb form, referring to the process of doing so, is "back up", w ...

file comparisons of each edit, so there are the previous versions of the file can still be accessed once the original is overwritten.
*
File locking, which limits the file to one editor at a time to prevent edit conflicts. Computer writer Gary B. Shelly notes that many
wiki systems "will block the contributor who is attempting to edit the page from being able to do so until the contributor currently editing the page saves changes or remains idle on the page for an extended period of time."
*
Merge, by determining if the edits are in unrelated parts of the file and combining without user intervention.
Occurrences
The problem is encountered on heavily edited articles in
wikis (frequency higher in articles related to a current event or person),
distributed data systems (e.g.,
Google Sites), and
revision control systems not using
file locking,

as well as other high-traffic pages.
If a significant amount of new text is involved, the editor who receives an "edit conflict" error message can
cut and paste the new text into a word processor or similar program for further editing, or can paste that text directly into a newer version of the target document. Simple
copyediting can be done directly on the newer version, and then saved.
