Allocation unit size and maximum file size

[Rolci]

I've been searching the net in vain. I need a table that shows the maximum size of a file that a HD can hold in NTFS when formatted in different allocation unit sizes. Hope that makes sense. Thanks

"With the NTFS file system, you can have a maximum of 2^32 clusters per file. This is an implementation limitation, not a file size restriction."

AIUI, this means that a typical NTFS installation that uses 4KB clusters will have a maximum file size of ...

2^32 x 4KB = 16TB

AFAIK it does not depend on allocation unit size. As implemented, the maximum file size in NTFS is just under 16Tb -- 1 cluster under. Take a look HERE.
