Description Paul Pazderski CLA 2019-07-30 10:26:51 EDT 
See also bug 549643 comment 5.

A Portable Device is e.g. an Android smartphone attached trough MTP or PTP.

The old FileTransfer before bug 547634 could not drag files to Windows Explorer where a Portable Device is the drop target. After adding CFSTR_SHELLIDLIST support the Explorer signals to accept the drop but the actual transfer fails always.

It seems as if the target does not like the fake PIDLs we create for ShellIDList. (for details see bug 547634 comment 5ff)

A solution might be to extend our native PathToPIDL function to create real PIDLs and only if that fails (usually if the file does not exist) create fake PIDLs.
