Merge files with file names added

I want to merge several files with identical format:
file 1:
Code:
rs3094315       0.0006105222804 0.9528743638
rs3131972       -0.05461465109  0.3139864854
rs3115860       -0.06041530955  0.3195499498

file 2:
Code:
rs2073813       -0.06039552152  0.2956527097
rs11564776      -0.1864266568   0.1976612108
rs12562034      0.00225669783   0.8555456823
rs12124819      -0.05026905981  0.2383563616
...

For each file, they have a unique name as XX1.phe.ps. XX1.phe.ps I want to merge all the files AND, add part of the file name "XXX" to the first column.
So the expected output is:
Code:
XX1 rs3094315       0.0006105222804 0.9528743638
XX1 rs3131972       -0.05461465109  0.3139864854
XX1 rs3115860       -0.06041530955  0.3195499498
XX2 rs2073813       -0.06039552152  0.2956527097
XX2 rs11564776      -0.1864266568   0.1976612108
XX2 rs12562034      0.00225669783   0.8555456823
XX2 rs12124819      -0.05026905981  0.2383563616

How can I do this?
