What does file.info('X1.RData') say?

Do you get any output if you run print(readBin('X1.RData', raw(), 128))?

If this is happening on a Linux or macOS machine, the operating system
command xxd -l 128 X1.RData will give the same output in a more
readable manner, but the readBin(...) output from R should be fine too.
