The Collection (FSS) is a concise yet multifunctional professional file and document management software that uses the world's first supertree directory collection file system. It can be widely applied in managing personal multimedia data files (mp3, image files, movies, video files, etc.) and office files and electronic documents (Doc, Excel, PDF, etc.). It employs an original supertree directory collection file system, placing files in virtual file collections that can be dynamically combined, completely surpassing the limitations of tree directory structures and the physical location of file storage. With simple settings, it enables the management of various types, sources, and purposes of files and documents stored on multiple different physical drives within a single system. Furthermore, with the help of the intelligent "Relevance Query Guidance" function, users can quickly narrow down search scopes based on the relevance of file and document classification and according to their habitual retrieval paths, allowing them to swiftly find the required files and documents. Please pay attention to the use of "Grouping" and "Relevance Query Guidance" functions during the file retrieval process, as they will make your work twice as effective with half the effort.
