JavaProp new airfoil

In the program javaprop it is said that it is possible to use your own airfoil ( Nevertheless, some users may want to add their own airfoil data. This is possible in case of a local installation by storing additional files in the installation directory of JAVAPROP1. The files should be named "af_1.xml", "af_2.xml" and placed in the javaprop directory )
In my terminal i have this:

chavagne@chavagne-desktop:~/MH-AeroTools/JavaProp$ ls -n
