Problem with old schematics. (Need help of Dev/Old ownr?)

Since I joined this server, I made a lot of builds and saved them in //schem since the very first. I wanted to paste some old builds that where created like one year ago, aprox. I made a big building (Wich included redstone) and now that I paste it, it seems to be corrupted. The only thing that is pasted is 8 grass blocks. I would really like to get the archive of the building, and I don't know if it's corrupted or got replaced with those grass blocks. If someone has a copy of the schems made a year ago, please contact me if possible. The names are:
alien.schematic
alienisolation.schematic
alienisolation2.schematic
alienisolation3.schematic
These schems are a part of a Survival Horror RP map I made when I was a OP.
I would REALLY love to see them again. I worked for these for weeks.
I would post some cool pics about it, but I don't have any because I deleted my .Minecraft folder because of an error.



Here's an image of how it looks now.
Edit: Found out that the very first build I made is still here and is not replaced with grass blocks. Looks like some retarded replaced them. I still need help to recover them. This was and is still my biggest build in this server, I would really like to see it back.I will pray for the one who helps me every fucking night
Edit: I'm trying to get some old screenshots with recuva
Edit: I've lost another schem. smh
