.wav file limits?

[Netlist]

As the thread title says, does anyone know what the max file limit is for .wav files and why.
Some say 2Gb, others 4Gb.
I found out that when recording with Magix, the limit is 2Gb.
I will try with Audition.
Any input from bits and bytes gurus?

Not sure on a limit, but Windows FAT file system can only do a couple of gig, any more and you have to use NTFS.

Thanks, I know the limitations of FAT32 and I use NTFS.

The WAV format is limited to files that are less than 4 GiB in size, due to its use of a 32 bit unsigned integer to record the file size header (some programs limit the file size to 2 GiB). Although this is equivalent to about 6.6 hours of CD-quality audio (44.1 kHz, 16-bit stereo), it is sometimes necessary to go over this limit. The W64 format was therefore created for use in Sound Forge. Its 64-bit header allows for much longer recording times. This format can be converted using the libsndfile library. The RF64 format specified by the European Broadcasting Union has also been created to solve this problem.

I found this as well.
Here they talk about the 4 byte header and the unsigned or signed number.
I wonder who is correct.
