While working on the computer (Windows 7 - HP Laptop), I tried to move a large folder and the system/operation froze. I tried to kill the process from the task manager, then restarted the computer. After the restart the folder was missing from the original and the target location. I thought, if I restored to a point few days earlier, I would get the folders back. The folders seems to be there, but many files are missing (except execution files). However, if I do a "restore to a previous version" on an individual folder it seems to restore the files, but not recursively. It would take a long time to restore each folder individually. Are there any solutions to this issue? How can I determine if this a wider corruption of data/files/folders? Thank you.
