String variable size limit not 2GB?

My code reads files into a string for processing. Today it broke with the error "Run-time error 7 Out of Memory" on a file with LOF (size) 153,344,779 bytes. This is surprising since strings should be allowed up to 2GB. Previous files were easily read by this command:

Dim strFile As String
strFile = Space(LOF(iFileNo)) ' Set File Buffer Size

strFile is Null with this file, however, and this command results in the Error message:

Get iFileNo, , strFile ' Load text [get error Run-time error 7 Out of Memory]

I would greatly prefer using the Get statement to the alternative of the repeated Line Input and redim into an ever-growing array.

No idea if it'll make a difference but have you tried declaring the variable as Variant, or not typing it at all.

I'm a little confused though, you say that strFile is Null.:eek:

When is it Null? Before/after you've tried to fill it with spaces.

By the way why are you filling it with spaces and what would be the problem with using Line Input, perhaps a little looping too?

Dealing with string as big as that seems, to me anyway, a bit daunting.
