The developer has to write a version of "FindNextFile" for MTP :-)

That would allow traversal.

If you use MTPDrive and mount MTP as if it was mtpFS on Linux,
then it would get a drive letter and traverse via the build-in
MSDOS-era FindNextfile. There is a pair of routines, FindFirstFile
and FindNextfile, and those are important primitives for a lot
of windows activities.

It's not like Microsoft does not know how to do this. It
has the IFS thing (Installable File System) and if Microsoft
wanted to do a mtpFS like Linux or make a userspace program
like MTPDrive, they could easily do it. Microsoft invented MTP,
and it's likely "clumsy on purpose". No attempt made to integrate
it properly.

MTP, part of the reason for even inventing it, was to enforce DRM.
If a camera device had the "DoNotCopy" bit set on a file, then
MTP could be used to enforce the "can't make a copy' thing. An
attempt to copy a DoNotCopy file, should fail. However, I've not
read any user accounts of actual DRM-fueled failures. Most of the
materials stored in a persons DCIM are going to be locally
captured with a camera sensor, not "stolen from Hollywood".

On a PVR, I doubt the interface on the thing is MTP, but I could
be wrong. That would be a perfect place to throw up a blanket wall
of "copy failures" as DoNotCopy is set on just about everything
coming through the TV antenna.
