A "???" file usually means Windows can’t classify it because the extension is incorrect or the file is partial, so turning on "File name extensions" shows whether it’s actually .pdf, .zip, .mp4, and if none appears, it may be intentionally extensionless; checking file size distinguishes broken downloads from real data, and magic-byte checks via Notepad—looking for "%PDF-", "PK", "MZ"—can reveal its type, with the containing folder providing additional hints, and trying common apps like a PDF reader, 7-Zip, or VLC often confirms what it is before you rename it properly.
When I said "???" isn’t an actual format, I meant it’s just what the OS shows when it cannot determine the file type because the extension is missing, since file identification normally comes from what follows the final dot; if the file was saved without an extension, renamed incorrectly, given a rare suffix with no associated program, or downloaded incompletely, the OS may mark it as unknown—even as "???"—but the file still has a real type you can find by checking its full name, size, signature bytes like %PDF- or PK, and origin so you know which app to use.
When I say "???" is usually a label rather than a real extension, I mean it’s just something the OS displays to mark a file as unknown, not an actual suffix like .pdf or .jpg, since a true extension is whatever comes after the last dot and tells the system which app should open the file, while a label is merely a friendly type description, so if the OS can’t identify the file because the extension is missing, uncommon, or the file is incomplete, it may show "???" even though the real format is still there, which you find by checking the filename, file size, and magic bytes.
When I say "???" shows up due to the system not knowing the type, I mean the OS needs a dependable clue—typically the characters after the last dot—to classify the file, and when that extension is missing, or when the file’s contents contradict it, or when corruption prevents header reading, the OS defaults to "???," with certain apps doing the same when no metadata or association exists, though the underlying format can still be found via the extension, file size, or first bytes like %PDF-, PK, or MZ.

Think of it like this: the file extension serves as a readable label for selecting the right app—PDF reader, image viewer, archive tool—and "???" just means that label is missing, leaving the OS uncertain even though the file itself may be fine, and checking the extension, file size, and internal magic bytes usually clarifies what the file truly is.
