File size limitation

Is there a file size limitation? And if so how can I
increase it to at least 1.5 gb or higher? Right now the
largest file I can create is 933 mb (.avi file)
 
From the filesystem team's internal website:

Maximum file size:
FAT16 = 2^32-1 (that's 4GB minus one byte)
FAT32 = 2^32-1
NTFS = 2^44-64KB (that's 16TB - 64KB and has been tested!)
UDF = 2^64-1

And just for kicks...

Maximum volume size:
FAT16 = 2GB (Win9x) or 4GB (Win2K)
FAT32 = 4,177,918 clusters (Win9x) or 2^32-1 sectors (all OSes)
NTFS = 2^32 allocation unites (tested to 17TB)

Files per volume:
FAT16 = 2^16
FAT32 = 2^32
NTFS = 2^32-1 (that's four billion files)

Files per directory:
FAT16 = 2^16-2 physical directory entries (affected by long filenames)
FAT32 = 2^16-2 physical directory entries (affected by long filenames)
NTFS = No limit

My parenthetical notes are abbreviations of the full explanations given by
the filesystem team but retain the essence of the footnotes.

NTFS can have 4^32-1 folders, since a folder in the NTFS filesystem is just
a file with special attributes.

From the resource kit;

Fat32 files per volume is approximately 2^32
NTFS files per volume is 2^32 -1

Also these may help.

Bjorn,
I didn't get a chance to respond till tonight, but it looks like Matthew
Mucker has answered for us.
 
Thank you Matt. I'll save this away somewhere. BTW didn't you mean 2^32-1
below?

The Win2000 Resource Kit says, in table 17.4, that max files per volume in
FAT32 is limited to 2^22:

Either the resource kit, or the internal web site, should be corrected...
:)

Best regards

Bjorn
