Indexing is the process of reading media files, extracting just the metadata for each file, then storing that data in an associated database so that it may be displayed in the columns of a DigiBase browser. Once a volume or folder has been fully indexed, it can be searched very quickly because all of the metadata has already been sorted and organized.If a volume or folder has not been indexed, it is indexed automatically the first time it is opened in a DigiBase browser. Volumes or folders containing a lot of media files can take a long time to index. For this reason, you may want to manually index specific volumes or files prior to starting a project to help expedite workflow.
