Open PART files in your browser
A .part is a file Firefox or a download manager was still downloading when it stopped. See what arrived right here, as the file it was becoming. Nothing leaves your device.
Or drop it anywhere on this page
What you'll see
Your unfinished download opens as the file it was becoming, as far as it got, with a coral mark that says so.
- Opens as its own file • Photos, songs, documents and archives
- A cut ZIP listed • From each file’s own header
- Unfinished download • Marked beside its details
- Every byte in the hex editor • See where it stops
About PART
Firefox writes a download into song.mp3.part and drops the .part once the last byte is in, and download managers, the old Internet Explorer and Edge, with .partial, do the same. When a download stops, the .part stays behind with everything up to where it stopped, and Firefox leaves an empty file under the real name beside it.
Filepeek opens it as the file it was going to be, by the name before .part: a song plays up to where it stopped, a photo shows as far as it came, a video plays when its index came first, and a ZIP lists its files from their own headers. A coral Unfinished download mark beside its details says it’s cut short.
eMule keeps its downloads as numbered .part files with a .part.met beside them, and their pieces arrive in any order, so one opens as what it is only when its start arrived first. Every .part’s bytes are in the hex editor.

Questions
How do I open a .part file?
Drop it here. It opens as the file it was becoming, as far as it got.
Can I resume a .part download?
Firefox can, from its Downloads list while the download is still there and the site allows it. Otherwise download the file again.
What’s a .partial file?
The same thing from Internet Explorer and the old Edge: a download that never finished. It opens here the same way.
Why is there an empty file beside my .part?
Firefox keeps the file’s real name free with an empty file while the .part fills. What arrived is in the .part.
Can I open an eMule .part file?
One whose start arrived opens as far as its pieces run without a gap. Its .part.met only lists which pieces came, and opens on its About card.
Is it safe to delete a .part file?
Yes, once nothing is downloading it. It only holds the part of the file that arrived.
