I created a new folder with the same name as the old folder and unintentionally started the merge process. I didn't want to wait for the folders to finish merging because there were a LOT of subfolders and files, so I stopped the merge. For some reason however, the majority of the subfolders have disappeared. I have "show hidden files..." checked and I have "hide protected operating system files" unchecked and they are not showing up. Nothing is in the recycle bin. My hard drive also suddenly has a lot more "free space" then it did before. I don't know what happened, maybe the links to the folders were broken? I can't even search for the missing files and folders.
