filelist lacks items
Consider a folder with 42 files.
One of the file is a hidden file like
.htaccess the others are numbered from file10 to file50
Since each page in the filelist only shows up to 40 element and hidden files are not shown I would expect to see file50 as single item on the second page.
What actually happens is that the second page shows file49 again and file50 is never shown!
The reason is that LocalDrivers folder traversal logic uses the offset parameter (40 in case of the filelist) to forward the iterator to this starting point. This is wrong, since the iterator storage may contain elements before the offset, that might be filtered away by file filters (like hidden files).
The correct solution is to iterate over the whole storage and decrease the offset whenever a potentially valid file is found.
This way the expected behaviour can be seen.
