OPDOWNLOAD File Extension

Have a problem opening a .OPDOWNLOAD file? We collect information about file formats and can explain what OPDOWNLOAD files are. Additionally we recommend software suitable for opening or converting such files.

What is the .OPDOWNLOAD file type?

The verbose .opdownload extension does not represent any specific file type or format. Standing for 'Opera Download,' this extension is used exclusively by the Opera web browser to label any files currently being downloaded. Opera is a free closed-source full-featured web browser available from Opera Software for all main platforms (PC/Mac/mobile) and operating systems.

The .opdownload extension is appended by the Opera browser to the original filename and extension of a file being downloaded. Once the download is complete, the temporary extension is automatically removed, restoring the original file type.

The presence of any .opdownload files in the download directory used by Opera means that there are unfinished download tasks that were paused, broken or abnormally terminated. Most unfinished downloads can be resumed or restarted anew.

Such .opdownload files are generally useless because they are not whole and their integrity is broken. This especially applies to archives and digitally signed files. However, some video files still may be played back partially if the .opdownload extension is manually removed.
