Pack complete local playlist references

Select the task inputs together

The original user wanted the tracks referenced by a playlist collected into one folder. Their later update used M3U and still asked for a GUI. T312 handles that selected local reference task with a complete package: UTF-8 extended M3U/M3U8 plus all media originals. It does not read WPL, search your disk or fetch a URL.

Files ending in .m3u or .m3u8 are playlists; every other selected file is an opaque media original. Select each referenced original yourself. Exact duplicate selected basenames reject the batch because one reference could otherwise identify multiple originals.

Bind paths explicitly

A bare line track.wav can match a selected track.wav exactly. C:\Music\track.wav, ./Album/track.wav and file:///Music/track.wav require a binding pair even when their last filename matches. A basename cannot prove that an old path refers to the chosen original.

Enter a JSON array of pairs, for example [["C:\\Music\\track.wav","track.wav"]]. For a local file URI, bind its exact original literal, including percent encoding. Parsing a URI only checks the supported syntax and its basename; it never navigates or resolves the URI. Duplicate bindings, missing selected targets and bindings not used by the selected playlists all fail the batch.

• Use [] only when all references are exact bare selected filenames.
• No host or localhost is allowed for file URIs; query, fragment, credentials and remote authorities are refused.
• A remote URL, nested playlist, HLS or unknown #EXT directive is outside this profile.

Keep repeated occurrences and metadata

In the checked example, first.m3u8 references 曲一.wav twice and second.m3u8 references 曲二.wav once. The two playlist outputs keep all three occurrences; media/0001.wav is copied once and referenced twice. The # retained comment, original EXTINF title and duration text stay in their original occurrence groups. unused.wav appears in the complete report but is not copied.

Apply the budgets together

Select 1–10 playlists of at most 1 MiB each and 1–1,000 media originals of at most 20 MiB each. All selected bytes together must fit 80 MiB. The published workload also limits physical lines and reference records; empty lines count toward the physical-line ceiling.

Use complete downloads and recover cleanly

Download the ZIP and full JSON/CSV. JSON includes every original playlist hash, every ordered reference, comments, EXTINF, explicit binding, copied original hash and unused selected original. CSV protects formula-leading cells with an apostrophe; the exact source literals remain in JSON. The table previews 200 rows and 2,000 UTF-16 units per cell.

Extract the whole ZIP together so the generated relative paths remain valid. The tool does not decode media or guarantee your device supports the suffix or codec. Reports retain original path literals, so choose which files to share deliberately. A failed or cancelled batch publishes no partial success archive; fix the named cause and rerun the same supported originals.

• The native capacity proof copies all 1,000 selected small WAV originals and independently checks every ZIP entry byte and CRC.
• The 80 MiB and exact 10 MiB report vectors are actual source data; first excesses reject the whole batch.
• Actual unfinished Worker hash progress can be cancelled, then the same originals can be recovered without an artificial delay. Native proof does not replace the final browser checks.
