Sessions & Tracks : Mac HFS+ Disk Support Option (Windows Only) : Session Compatibility

Session Compatibility
The Mac HFS+ Disk Support option enables Windows to recognize Pro Tools sessions created on Mac-based Pro Tools 7.x–9.x (.ptf) and Pro Tools 5.x–6.x (.pts) systems.
Mac-based Pro Tools 5.x–6.x sessions that reference audio files in Sound Designer II (SD II) format are not supported on Windows.
If your Mac-based Pro Tools session includes any audio files in SD II format, you will need to return to the Mac-based Pro Tools system and re-save the session so that its audio files are Windows-compatible, then open it on your Windows system.
To save a Mac-based Pro Tools 5.x–6.x session with SD II files to be Windows compatible:
1 Open the session on the Mac-based Pro Tools system.
2 Choose File > Save Session Copy In.
3 In the Save Session Copy dialog, select Enforce Mac/PC Compatibility.
4 Choose the audio file type (.WAV), sample rate, and bit depth for the session.
5 Choose a destination and enter a name for the new session.
6 Click Save.
