File Virtualization is an aspect of storage virtualization which operates on a computer file level and involves bringing together multiple storage devices into a single, overarching collection of files.

To put the need for file virtualization in perspective, consider a company that has thousands of employees at different locations. When you have people travelling and moving in between cities or even areas within the same building you need to have a clear understanding of how data is being stored and utilized as well as the ability to map it to use the resources more effectively. For example, file virtualization might give you the ability to access your files from wherever you are physically located.
