The extension .OPDOWNLOAD stands for Opera Partially Downloaded File. Developed by Opera Software this is categorized under Misc files. This extension is used for temporary files created while files are being downloaded – until the download is completed successful. The extension is changed to the document or images actual extension once the download is 100% completed and only then can the file be used. The OPDOWNLOAD files are similar to the files used in Google Chrome (.CRDOWNLOAD) and Mozilla Firefox and Apple Safari (.DOWNLOAD). Even if the download is not completed successfully you can attempt to open these files by removing this extension and replacing with the correct file extension.
