I started downloading a video from savefrom.net. Due to some error the video did not download completely. I came to know that you can't watch the incomplete video that's ok but i have very less space in my hard disk. Where is incomplete downloaded video stored.
It depends on which application you were using. For Firefox, it's where you downloaded it to, probably the Downloads folder in your home directory. For Chrome, I think the temporary file gets deleted.
Incomplete downloads are stored in /tmp directory in Ubuntu. Unfinished or corrupt files are automatically deleted after each reboot.
