restoring deleted realplayer file by mistake ( ever have a solution?)

I had a library of videos as a section of my realplayer .
the videos were directly downloaded from youtube by the common relplayer tag .
then you know that it is getting downloaded into a file called : ' videos ' in the system
accidently I deleted that file tonight and I seek a way to get them back
they are videos gathered over years ...
I did a system restore but it seems that it has nothing to do with documents .
I don't want to go to the mess of recovery softwares because those files deleted were realplayer video files usually found in library of RP and Videos folder in the system and they are not normal files .
I applied a trick as :

1. go to your realplayer
2. on the top left corner u see the word realplayer with the arrow pointing down, click on it
3. click file
4. then click scan disk for media
5. then a window should pop up and u click next 2 times
6. then u have all your videos back!!!

but nothing except realplayer video files existed out of the videos folder i.e in D or somewhere else survived .
in fact thise files could not be called restored , there didn't get deleted first of all .

this shows how the things are

the valid files are those which initially did not get removed by mistake .
the red -crossed ones are those which are deleted by mistake and which crucially important I need them back . as I told you files were downloaded over the years and well classified + categorized .

Any one knows how to get them back ?

there is nothing in the recycle bin .
they were supposed to go to rec bin to enable a user to atleast take a reverse decision or a step back .
it is a strange problem .
how sometimes data are recovered from physically damaged HDDs or effected by malware by using techniques like the recovery software , on the other hand for my simple case .... thing might be difficult .
it could be a computer science paradox !
