[AccessD] Edit Large text file via VBA

Instead of 

Strtemp=space(lof(f))

and then Get() ing the whole file, define a chunk of (say) 50,000,000 bytes.

Then you need a loop to Get(CHUNKSIZE), do the replace on it, write the
chunk to the new file and then go get the next chunk.

Repeat until done.  This should be much faster that using  Line Input #1, to
process it a line at a time.

Thanks again Drew.

I might have forgotten to mention that these are farely LARGE text files.  
The one it is crashing on is 138 mb ...error= "Out of String Space"

Any other ideas?

Thanks again,

Mark A. Matte

P.S...  The largest is just over 150 mb
