Q:

Issues with one library unable to Open with Explorer

My users are able to use Open with Explorer on a regular basis. In one site collection, there is one library with special permissions in which the following error comes up when trying to Open with Explorer:
"Windows cannot access \mysite.site.org\DavWWWRoot\sites\etc\etc
You do not have permission to access \mysite.site.org\DavWWWRoot\sites\etc\etc. Contact your network administrator to request access."
Both the user and I have Full Control over the site and this library. There is also another library with identical access levels that we are able to Open with Explorer. The Admins recreated the library that is not working and copied over the contents exactly, and now the duplicate library is having the same issues. 
We tried opening another library and navigating to this one, with the same error.
Any ideas on how this can be fixed, or why it may not be working?
Thanks

A:

Issue fixed - In case anyone else runs into this, it actually turns out the user had named a file with a "." at the end (i.e. filename..docx), removing the "." corrected the issue.
