Use the command line to CD there and then the MD command to make a folder. It's not hard and could reveal something. Remember that Explorer takes it cues from a few hidden files in the folders so I suggest you research how that works.
For now, try the old command line.

I am running Windows 7 on a brand new Lenovo lap top. It is a new environment all around. I found one glitch in the Windows Explorer application. I created a sub-directory in the Documents Library and named it Michigan. I have done the same for folder for Indiana, Illinois, and Kentucky etc. etc. with no issues. But the one I created and named Michigan (not the first one I created either) I cannot add sub-directories to it, or when I try to copy and paste a sub-directory, the files go in but not the directory. Across the top of the all the other directories there is an option for ?New Folder? but not in the one I named Michigan. I don?t want to delete and rename the file as I have a spreadsheet that has many hyperlinks pointing to many Word documents in the Michigan folder.
Have you seen this before? Is there a fix?
