Question

Am I correct in thinking that FAT 32 will only allow filesizes up to 4 gig? If so, would I have to format the drive into NTFS?

The maximum file size on a FAT32 formatted partition is
4 GB or 4,294,967,296 bytes minus 2 bytes.

If you're talking of filesizes over 4GB then you want to use NTFS anyway for the reliability.

Question

I thought FAT16 had the 4GB limit?

AFAIK FAT32 has a 2TB limit, i.e. 2048GB.

Errr no, you should be able to format up to 2048 GB using FAT32.

Might also depend on whether or not your BIOS can handle that size.

Ooops sorry just reread that it is filesizes you want not disk sizes Sorry!!!!

Then yes, I think there is a 4GB limit on filesize, so you will probably need to go to NTFS. NTFS allows 2TB.

rik1471 was right (should have read the post properly before posting!)

Thats true, but he's talking about a filesize of 4GB, not a partition size.

Formatting a partition of 2T will still only allow a file size of 4GB max.

Anything bigger, you will have to use NTFS.

EDIT : Dammit, can people stop editing their post when i'm replying

And nope, you can convert to NTFS without losing any data.

You just won't be able to convert back without using something like Partition Magic.
