Missing folder

hi, i had a folder with thousands of files(images) and hundreds of folders in it that i used to work with. my windows is 10. once it requested to do a restart to fix one of drivers and after the restart when i tried to open than large folder an error message poped up saying the directory is corrupted and unreadable. i tried the [chkdsk] command and it didnt work. then i performed a disk check and after that i found out the folder wasnt there anymore! every thing else in that driver is there except that! i made a file recovery with O&O but it brought back all the files in drive g without any specific order. i found a few of pictures that were in that folder and the names of them was changed with each other! what should i do? i need all of them in their own specific order! someone please help!
