A YDL file is rarely a universal format used to store queues, item lists, progress markers, and configuration so a program can pick up where it left off, and while some YDL files are text-based and readable—showing JSON, XML, or URLs—others are binary and unreadable outside the creating app, making the fastest identification method checking its origin, folder, size, and associated program to know whether to open it directly or import it into the software that produced it.

When people describe a YDL file as a “data/list file,” they mean it acts as a program-managed data record instead of something meant to be read like a document, effectively working as a saved queue or inventory of items—URLs, batch entries, playlist elements—plus metadata like names, IDs, dates, sizes, progress flags, errors, retry counts, and output destinations, letting the software reload state, skip rescanning, and keep work consistent; sometimes it’s human-readable JSON/XML or line-based text, but often it’s binary for efficiency, with the central concept being that the YDL directs program behavior rather than being opened manually.

Common examples of what a YDL file might store include a predefined set of entries the program works through such as download links, filenames for processing, database IDs, or playlist components, plus metadata (titles, sizes, timestamps, locations, tags) and workflow settings like output targets, quality options, filters, or retry counts so the app can reopen with everything intact, sometimes acting as a cache/index to speed loading and track statuses (pending/success/failure), making it a machine-friendly record rather than a user-facing file.

A YDL file is most often a program-produced “working file” that acts as internal session data rather than a user-facing document, serving as a list plus state for items such as downloads, media objects, batch inputs, or library members while keeping related context—IDs, file paths/URLs, names, sizes, timestamps, settings, and progress indicators—so the application can resume smoothly and avoid rescanning, which is why it often sits alongside logs, caches, or mini-databases; some YDLs are plain text, others binary, but all act as machine-readable containers for items and their processing details.

In real life, a YDL file typically acts as a hidden workflow record the app builds automatically, holding downloader queues with URLs, output names, folders, and progress states, or storing media-collection items with metadata like titles, durations, thumbnails, and tags; some tools treat YDL as a batch-recipe file listing inputs and options, while others use it as a cache/index to skip rescanning large folders, and in every case the file exists so the software can restore lists and states across sessions rather than be opened manually.
