I'm not sure if this is the right place for this question. I've also tried searching for answer.
I have a DS211J, I upgraded it recently to the latest frmware. Everything has been running smoothly until last night.
I was organizing some folders and created a new folder called "Books" to hold files. In the Synology "web page" for lack of a better term, I moved another folder (that contains many subfolders and files) into my new Book folder. I can see and access the folders and files fine in the Synology web page, but I can't access the sub folders in my Windows PC or from my iPhone app for that matter. If I try to access it via Windows explorer, I get a "can't access folder" error message when I try to access the sub folder, 2 levels down from the one I created. On the iphone app, I can get into the folder, but it'll just there are no contents to display.
Anyone experienced this before?
