Odd issue which I haven't seen before, and which is leaving me baffled.
In a Sharepoint 2013 subsite, I have a single Document Library which has been renamed from the default Shared Documents library. In it there is a directory structure, with some long named directories containing '-' but no other special chars. In the directories are a bunch of Excel, Word, Powerpoint, Visio and Project files. All pretty standard.
If I view the directory structure and files in Windows Explorer (i.e. Open with Explorer command) the directory structure and files contained within are correct. This is my default way of viewing, accessing and editing the files.
However if I view within IE (11, on Win 7) then a bunch of old files that have been deleted or moved to new locations are still visible in their old locations. And if other users add new files to the directory structure I can only see them in the browser.
I've double checked and there is no Version Control/Draft/Check Out/In settings enabled on the Doc Library. I have permissions to Edit/Contribute, and there isn't specific UPs on individual files as far as I can tell. Refreshing, clearing browser cache etc does nothing. This is not happening in other subsites/DLs to my knowledge.
Any thoughts/suggestions greatly appreciated.
