What happened to my files?

Hello there

I got strange problem, Few days ago ive placed(but not delete) some files in recycle bin.

Today ive move out these files into new folder, while looking into those files ive noticed some are missing, so ive thinking Maybe ive delete them accidentally?.

So ive launch recuva to check out did ive delete them, And recuva show these missing files are OK and never been removed, So if files are not removed from hard drive, Where they now if recycle bin are empty?
