Opera Download Stuck as an .opdownload File?

What an .opdownload file is

An .opdownload file is a partial, in-progress download created by the Opera browser (the same idea as Chrome's .crdownload). While bytes are still arriving, Opera writes them to a placeholder named after the real file with .opdownload added — for example setup.exe.opdownload. When the download finishes, Opera renames it to setup.exe and the suffix disappears.

Why it is stuck

If the .opdownload never becomes the real file, the transfer stalled — the connection dropped, Opera was closed, or the download was paused and lost. The partial data is unusable until the rest arrives.

How to finish it

Open Opera's downloads (Ctrl+J) and click resume. If the entry is gone, just download the file again from the source page.

Is it safe to delete?

Yes, once you have given up on it. Move the .opdownload to the Recycle Bin; you only lose the incomplete data, and the next download starts fresh.

How to finish a .opdownload file by OS

All systems (Opera): .opdownload is an in-progress Opera download. Open Opera, press Ctrl+J (⌘J on Mac) to open Downloads, and click resume. Don't rename it — Opera renames it to the real file automatically when complete.

Common problems

A stuck .opdownload means the transfer was interrupted. Resume from the Downloads panel; if the source no longer supports resuming, delete it and start over.

Other browsers name partial downloads differently: Chrome uses .crdownload and some download managers use .download.
