| ID | Description | Priority | |----|-------------|----------| | | Accept a single URL or a batch file (CSV/JSON) of URLs. | High | | FR‑2 | Validate URL syntax and perform a HEAD request to obtain Content‑Length and confirm Accept‑Ranges: bytes . | High | | FR‑3 | Split the file into N equal byte‑ranges (configurable, default = 4). Each range is fetched by an independent worker thread/process. | High | | FR‑4 | Write each segment directly to a pre‑allocated temporary file using random‑access writes (seek). No whole‑file buffering in RAM. | High | | FR‑5 | Persist a download‑state manifest ( .lfd file) alongside the target file, containing: • URL, total size, segment offsets, completed bytes per segment, timestamp, checksum (if provided). | High | | FR‑6 | On app start or on user “Resume”, read the manifest and continue only unfinished segments. | High | | FR‑7 | Provide Pause , Resume , Cancel controls. Cancel deletes temporary data and manifest. | High | | FR‑8 | Show real‑time UI : • Overall % and MB/GB • Per‑segment speed • Aggregate speed • Estimated time remaining. | High | | FR‑9 | Retry logic : On any segment failure, retry up to 5 times with exponential back‑off (initial 2 s). | Medium | | FR‑10 | Checksum verification : If the server supplies an x‑checksum‑sha256 header (or a separate .sha256 file), compute SHA‑256 on the final file and compare. | Medium | | FR‑11 | Progressive playback : As soon as the first segment (or configurable threshold, e.g., first 100 MB) is fully written, expose the file to a media player component (or OS default). | Low | | FR‑12 | Authentication : Accept optional Bearer token or Basic auth headers per URL (via UI or batch file). | Medium | | FR‑13 | Bandwidth throttling : Allow user to set a maximum download rate (KB/s). | Low | | FR‑14 | Logging : Write a detailed log ( lfd.log ) with timestamps, HTTP status codes, retry attempts, and final outcome. | Medium | | FR‑15 | Cross‑platform support (Windows, macOS, Linux) for the desktop client; optionally a minimal web‑client using Service Workers & Streams API (if browser‑based). | Medium | indir tusem tango mp4 10164 mb work
