Mike,

It would be a two pass thing, or a best guess. I would go with the best

guess.

A tight loop getting the data and dumping it as you get a total count, then

return to the top and begin processing.

If you did this, since you have multiple types of data in the file, you

could get a count of each type. Then show the progress of each type as you

do the real processing.

The best guess, FSEEK() to the end returns the total number of bytes. You

can use this and add the bytes of each line to show the complete progress.
