FAT32 works for both OSes, but has a 4GB size limit per file, so it. Windows' default NTFS is read-only on OS X, not read-and-write, and Windows computers can't even read Mac-formatted HFS+ drives. The app is fully integrated with Paragon File System Link document provider, based on Storage Access Framework (SAF), that ensures access to device storage, cloud storage services, USB storages. Microsoft exFAT/NTFS for USB by Paragon Software is a universal non-root method for transferring files between onboard memory of your Android device and Windows or Mac-formatted USB Flash Drive. For each file, exFAT uses two separate 64-bit length fields in the directory: the Valid Data Length (VDL) which indicates the real size of the file, and the physical data length.

Like NTFS, exFAT can pre-allocate disk space for a file by just marking arbitrary space on disk as 'allocated'.
