I upload binary files. The first is with a sin signal: usrp_output_64bit_complex_only_sin_signal.dat.html

These files came from some analog-to-digital converter? If you look at them with hexdump, there is stuff that looks like data only in the first 200 bytes or so. The rest of the file looks likes zeros and the occasional 0x80bf. I wouldn't expect the data read from these files to have a meaningful Fourier transform.
