You should only have one version of XAMPP installed - you can only run one instance of XAMPP at a time.
In the
C:\xampp folder, which BTW is the normal default install folder for XAMPP, and in the other installation folder, you should see a folder named
install, drag the file
xampp_version.txt file (
for 1.7.2) or
.version (
for version pre 1.7.2) into your text editor and it will tell you what version is installed in which folder.

XAMPP should only be in the one place and IMHO
C:\xampp is the preferred default installation - also you should be logged in as an administrator so you can effectively administer a web server effectively.
Just make sure that everything to do with XAMPP points to the installation location you choose.
If you are removing the folder with version XAMPP 1.7.2 then you can run the
uninstall_xampp.bat file first before deleting the folder.
BTW Joomla runs in XAMPP versions older that 1.7.2 so the folder with 1.7.0 will be fine for Joomla.
