Sessions created and saved as Pro Tools 7.x and higher sessions are always compatible on both Windows and Mac systems.
If you create a Pro Tools 6.9.x or lower session on a Mac system, the session is only compatible on Windows systems if the
Enforce Mac/PC Compatibility option is selected when using the
Save Copy In command. In addition, there are cross-platform limits to consider when completing the
Save Copy In command.
When saving (or creating) a copy of a Pro Tools session that you want to be compatible on both Mac and Windows, keep in mind the following limits and how Pro Tools deals with them:
The recommended file format for cross-platform interoperability is BWF (.WAV). To support optimal session interchange, Pro Tools defaults to BWF format for new sessions.
Pro Tools lets you save, bounce, and export in a variety of audio file formats, including WAV, AIFF, SD II, MP3, and QuickTime.
For cross-platform compatibility, all files in a session must have a 3-letter file extension added to the file name. Pro Tools 5.1 to 6.9.x session files have the extension “.pts,” and Pro Tools 5 sessions have the extension “.pt5.” Wave files have the “.wav” file extension, and AIFF files have the “.aif” file extension.
Clip names, track names, file names, and plug-in settings cannot use ASCII characters that are incompatible with either system.
When importing files into a session, incompatible characters are converted to underscores (“_”) and the renamed files are placed in the Renamed Files folder.
If the session previously used SD II files, the files are converted to the new audio file format.
