The ACDSee database stores image, document, and media file information automatically when you browse your folders. This process is called cataloging. The database increases the speed with which you can browse your files in ACDSee, and you can use the information stored in the database to sort, organize, search, and filter your image, document, and media files. You can also use the Catalog dialog box to add groups of files to the database without having to first browse the folders, though, during this time, you will not be able to use ACDSee.
However, the ACDSee Indexer allows the cataloging process to be undertaken when your computer is idle and ACDSee is not running. This allows you to avoid having to browse all of your folders, or experiencing disruptions to your computer's speed and usability, or cutting into the time that you are using ACDSee. If the files are modified in any of the selected folders, the ACDSee Indexer will automatically catalog them again to keep the ACDSee database up to date.
You can set which folders you would like to be cataloged and how long you would like your computer to be idle before the ACDSee Indexer begins to catalog your files. To configure these options, see Setting the ACDSee Indexer Options.
