Qfiling Automates File Organization

Qfiling helps automate file organization for sorting files spread through multiple folders, helping reduce the time needed to find important files. Users can categorize files, determine filing conditions, and schedule filing tasks to be carried out periodically. The "Recipe" feature allows users to save frequently-used filing conditions as an "exclusive recipe," then the next Qfiling task can be run with just one click using the recipe.


The TS-431X2 supports Qsirch, a search tool for quick file searching. Qsirch supports thumbnail previews and even remembers your search history, allowing you to quickly navigate to files you've previously searched for. The revamped Qsirch adds "search operators" and advanced search filters and tags, allowing you to find files faster with more precise results. Qsirch also provides a Helper for Google Chrome and Mozilla Firefox that allows you to search for files on your NAS when you use Google Search.

Centralized Email and Contact Management for Improved Communication Workflows

It can be hard to manage emails and contact information that are scattered across multiple computers, devices, and accounts - not to mention if important emails or contact information are lost or become inaccessible due to account closure or device malfunction/loss. QNAP QmailAgent and Qcontactz helps you centrally store and manage emails and contact information, making them accessible to your devices. Using the powerful Qsirch search engine, you can easily find specific contacts and emails whenever needed.

Notes Station

Notes Station helps organize notes for your personal and working life. You can easily edit text, insert images/files from the NAS, fine-tune images with the image-editing tool, create sharing links to share notes, backup/restore your notes with snapshots, and ensure privacy with password protection and encryption. You can also invite people to collaborate on notes for greater teamwork. Notes Station provides a safe and convenient way of taking notes that are fully under your control on your TS-431X2's private cloud.

Virtual JBOD

Besides using physical storage expansion enclosures, there is an additional option to expand NAS storage capacity. QNAP VJBOD (Virtual JBOD) is network-based JBOD, allowing you to expand the storage of a QNAP NAS by using the unused storage space of another QNAP NAS. The TS-431X2 supports VJBOD to economically expand the storage capacity of other QNAP NAS devices with its unused storage space. You can also create virtual storage pools and volumes on the virtual disks for operating NAS services.

Expand Storage Capacity

The TS-431X2 supports online capacity expansion by connecting two QNAP expansion enclosures for storing rapidly-growing data, which is well-suited for storage-intensive applications such as video surveillance, data archiving, TV broadcast storage, and more. You can gradually expand the TS-431X2's storage on demand, and use the QTS Storage Manager to easily handle the NAS capacity expansion and storage expansion enclosure management. With the support of QJBOD Express (JBOD enclosures roaming), you can just connect a large capacity QNAP expansion enclosure to the TS-431X2, and migrate data to another NAS through the JBOD enclosure without network connectivity.

The TS-431X2 is compatible with the UX-500P and UX-800P expansion enclosures. When using one UX-500P enclosure, up to 9 total drives (NAS + enclosure) are supported, while adding a second UX-500P supports 14 total drives. If you need more storage, adding one UX-800P provides users with 12 total drives and adding a second UX-800P increases that number to 20.
