Using stringWithContentsOfFile I can load an NSString with the contents
of a file (obviously).

What are the practical limits with regard to the size of file that could
be handled?

The NSString documentation references this from NSString.h

NSMaximumStringLength

A constant to define the maximum number of characters in an NSString
object.

#define NSMaximumStringLength (INT_MAX-1)

The practical limits I would expect are dependent quite a bit on the
specific machine and the amount of space available in the process's
address space; I wouldn't necessarily expect great performance handling
a 3GB string on a machine with 512MB of RAM, for example.

Overall performance would be a major factor for me, and I expect the
largest file I'd be handling this way would be in the 1GB region, but
mostly in the 250MB range.

Thanks for the info.

Depending on what you're doing with these files, you might want to
consider loading them as memory-mapped files. NSData objects can be
initialized this way, and you should be able to get an NSString from
there.
