Deleted folder keeps reappearing on desktop

Hi, I have a folder on my desktop which I used as a temporary location for pictures and videos. Once it was empty I deleted it but every time I open my internet browser it pops up again. I am using Mozilla Firefox and have checked the download settings but this folder is not named in any path that I can see. I also checked WMP but it doesn't appear there either. The only other program I used this folder with was Movavi to convert the video files to MP4 but it's not showing up there either. Any suggestions?

Thanks rich but after days of frustration I finally figured it out just after I posted for help of course! I had a toolbar that was using the folder as my default location. Changed it's path, deleted the folder and it hasn't come back. :)

the folder was created new when I started "Syncios" (programm to move pics and more from and to iPhone)
Deleted the program re-installed it many times. Still same Folder on desktop reappeared.
Than changed the default folders for music converted by Syncios. Did not remember I ever used this :)
And the folder never came back since.:)
