rem // to avoid using the Plan9 NTFS to ext4 bridge (9p file protocol) implemented by Microsoft that is notoriously slow.

rem // 1. fire up a file packer and create a SINGLE FILE archive of the directory hierarchy to copy
rem // 2. copy the file over to WSL
rem // 3. unpack the archive in /tmp/qnxsdk and delete it - as it's much faster to migrate a single file than a folder hierarchy

rem // We might be able to do this by using the "tar.exe" utility from the QNX8 Win64 host SDP tools and piping the data
rem // through a wsl instance which would in turn untar it directly at its location. Investigate.
