Conversion of crdownload files to avi file format

It is certainly possible that some downloaded videos (.avi files) might have been be saved as .crdownload files by Google Chrome web browser until the download is successfully finished in which case these suffix should have been renamed back to the original. 

As far as we are aware, there doesn't seem to exist a reliable way how you can recover the video from unfinished download, which usually means you have to download the file again and let Chrome finish the download properly.  You might try to rename it manually to AVI and at least partially playback, however, it will be most likely corrupted heavily.
