The Impulse file is too large but here is the beginning

Is there a way to send very large files? I cannot seem to attach the .txt impulse file. BTW the REW header is not used it is there just so I can debug in REW. I geneated the function by measuring with REW and my own Fourier transform. When I run this it dous seem to give the correcet amplitude results with a frequency sweep. It is a symettric impulse response and should have linear phase. REW says it does too. The phase plot from the moode pipeline editor  bugs me and must be wrong.
