DtSearch Desktop provides instant searching of desktop-accessible files. dtSearch can instantly search terabytes of text because it builds a search index that stores the location of words in documents. Indexing is easy — simply select folders or entire drives to index and dtSearch does the rest. Once dtSearch has built an index, it can automatically update it using the Windows Task Scheduler to reflect additions, deletions and modifications to your document collection. Updating an index is even faster, since dtSearch will check each file, and only reindex files that have been added or changed. The dtSearch indexer automatically recognizes and supports all popular file formats, and never alters original files. The dtSearch product line can instantly search terabytes of text across a desktop, network, Internet or Intranet site. dtSearch products also serve as tools for publishing, with instant text searching, large document collections to Web sites or CD/DVDs.
