jquery.idle | dead simple jQuery plugin that executes a callback function | Plugin library

So I've done a lot of research so far and haven't found even a hint of something that could cause this. I put htaccess in the tags since I thought that could technically do it.

The problem is this: I have a server to migrate. So I want to download all the files from the old server, and then reupload to the new server. What happens when I go to the online file manager and click compress and download is that a very important folder is missing from the zip (and judging by the counts there are others missing too).

I've also used Filezilla to recursively download the whole directory structure, but it also misses that folder. Even stranger is that Filezilla sees the folder and I can download it directly, but if I recursively download the folder just above it, it doesn't grab it. It's the same with the online file manager, it sees it too.

I even wrote my own c# program to do a basic directory listing and it doesn't see it. It uses an FtpWebRequest with Method set to WebRequestMethods.Ftp.ListDirectoryDetails.

So the problems persists on both server side functions as well as the client attempts through FTP protocols.

There is an .htaccess file specific to the folder in question but I can't see anything that might do this. (Included below)

Does anyone have any ideas? I'd be most grateful for any hint
