[File Types] Incomplete Download Part Files

raccoon · Post by **raccoon** » Fri Dec 04, 2020 8:00 pm

This is a list of suffix file extensions that are appended to the end of file names being downloaded by various network client file downloading software, ie, by download managers, torrent clients, web browsers, and other downloader programs. When a download in one of these programs is completed, the suffix file extension is removed. A file with one of these extensions indicates that it has only been partially downloaded and should be treated as incomplete, unfinished or corrupt. (i'm using searchable keywords here).

All of the following file extensions are added to the end of the regular filename and extension. example: samplevideo.mp4.crdownload

Some of these file extensions may be used by other software for other purposes. Conflicts noted below.
