Thanks for posting that log and the new detail. This definitely narrows it down.
I took a look at the EnumDirectory function, and it filters based on a file's attributes. It will drop any file or folder that has any of the following file-system attributes on it's directory entry:
FILE_ATTRIBUTE_DEVICE
FILE_ATTRIBUTE_OFFLINE
FILE_ATTRIBUTE_SYSTEM
FILE_ATTRIBUTE_HIDDEN
FILE_ATTRIBUTE_TEMPORARY
Try right-click > properties in the Windows file explorer and there are probably some checkboxes in there to toggle the hidden or temporary attributes.
If you open a command prompt, I think there's also the
attrib
command that will list the files and attributes in the current working directory. You could use that to check what's going on with those files. The manual page for that command appears to be at
