# Core Features

* **Near-Instant Indexing:** Upon first launch, it rapidly scans the Master File Table (MFT) of NTFS volumes to build a lightweight index of all filenames and paths. It then monitors the USN Journal to keep this index updated in **real-time** as files are created, deleted, moved, or renamed.
* **Lightning-Fast Searching:** Searches based on filenames, paths, or parts thereof return results almost instantly, even across terabytes of data.
* **Low Resource Usage:** Consumes minimal CPU and RAM during both indexing and searching operations, making it suitable for use even on lower-end systems without significant performance impact.
* **Powerful Search Syntax:** Supports much more than simple keyword searching:
  * Boolean operators (`AND`, `OR`, `NOT` represented by space, `|`, `!` respectively).
  * Wildcards (`*` for multiple characters, `?` for a single character).
  * Regular Expressions (regex) for complex pattern matching.
  * Specific filters for file size (`size:`), date (`dm:` for modified, `dc:` for created, `da:` for accessed), attributes (`attrib:`), paths (`path:`), extensions (`ext:`), and even file content (`content:` though this is much slower).
