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 functions as a reusable internal list 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 an ordered set of items awaiting action—such as URLs, filenames, IDs, or playlist entries—along with metadata like titles, sizes, timestamps, tags, source paths, or identifiers, plus task-specific settings (output folder, quality, filters, retry limits) so the program can reopen and continue seamlessly, sometimes also acting as an index or cache for faster loading and tracking statuses like pending/success/failed, making it a machine-friendly record combining items with context rather than something meant to be opened manually.

A YDL file is most often a program-created "working file" that acts as internal project data rather than something meant to be opened directly, typically functioning as a saved list plus state by recording which items belong to a job—downloads, media entries, batch inputs, or library records—along with identifiers, URLs or paths, titles, sizes, timestamps, chosen settings, and progress flags (queued/in-progress/completed/failed), which is why it tends to appear near logs, caches, and small databases to help the software resume work, avoid duplicates, and load faster; some YDL files are readable text (JSON/XML/key=value), others are binary, but both serve the same role as a machine-friendly container for items and the context needed to restore them.

In real life, a YDL file typically acts as a hidden workflow record the software uses internally, 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.
