Getting count of rows in a text file -- best approach?

VF9SP2

Currently, I'm simply doing this for now:

RowCount = OCCURS(CHR(13),FILETOSTR(m.Filename))

Is there a better (read: FASTER) way? These are tab delimited text files so I can't really use FSEEK or FSIZE(m.Filename) (which requires SET COMPATIBLE ON) because I can't be sure of each record's length.
