Files with different sizes to recover them are left with 256kb

I have a small problem that is weird, I see the images that I deleted, but when recovering they all have 256kb
The weird thing that in the program the images have different sizes but when recovering them all they have 256kb so they appear corrupted when opening them!
that I have to modify, how can I make the integral files appear?

Are they in the $CarvedFiles folder or in a normal directory?

What file system type is it?
