Hello. Your folder name contains spaces and punctuation, so the path must be written in quotes. Also, to recover everything inside a folder, you need to explicitly tell the tool to include all files.
Try this:
winfr C: E: /regular /n "\Users\wadav\Documents\davila-snchez, william a\*"
If the folder was deleted a while ago or emptied from the Recycle Bin, /regular may not find it. In that case, the scan needs to be deeper and will take longer.
