Rightclick at the file and choose 'Show File Details'.
In the line 'met-File', there's a number. (e.g.
temp/006.part.met)
Go into the temp-folder and copy the file with the number and the extension .part in another directory. (e.g.
temp/006.part)
Then rename this file to filename of your avi-file. There will be something missing, because the file is not finished, but it shall be better than nothing.
