This isn't a WHS-related post, but I'm throwing this out to Google as a vote for a specific solution to a specific problem. If you're trying to copy some really large files from an OSX user, ones that don't fit on a FAT32 volume, use HSFExplorer.
To transfer large files from an OSX machine to Windows, if you don’t want to mess around with Bootcamp drivers:
- Copy large files from the OSX machine to an HSF-formatted USB disk
- Plug USB disk into your Windows machine
- Run HSFExplorer and locate the HSF volume
- Right-click the files you want and choose ‘Extract’
Works just like any archive unpacker (WinRAR etc). Highly recommended.
