Version Control

19 January, 2016 - 17:37

Files such as word processing documents and spreadsheets may be stored on an individual’s computer and copies sent to participants who then make changes and return the revised version to the person who is responsible for the final version of the document. If more than one person is editing his or her own copy of a document at the same time, different versions of the document with different additions or corrections are created. Word processing programs such as MS Word 2007 have a feature that can compare two documents and identify the differences to help bring the two different documents back together. This feature is found on the Review tab, in the Compare group, as shown in Figure 6.22.

Most software programs make periodic backups to protect from accidental power loss. One of the ways that a user can still lose a lot of work is by replacing a newer version of a document with an older version. It is possible to display the date on which the file was last saved using the Details view. If more than one version of the file exists in two different locations, the dates can be compared to determine which is the most recent. These techniques are useful for simple projects with very few participants.
