Installation of Appl. / Files with Extension *.paf.exe / Which XAMPP version / Forum search

Hello,

today I started with using PortableApps and installed it on an external HDD.
All it works and it's brillant. Thanks for it.

Now I have some questions, for them I don't found answers on this Website and Forum.

1. In which folder I should install additional application general? Maybe into subdirectory .\PortableApps\PortableApps\{app dir} of my portableApps installation, isn't it?

2. Where I could find application files with extension -> .paf.exe?

3. Which version of XAMPP I should use and how to I install it? I know that's existing 2 versions for Windows -> XAMPP for Windows and -> XAMPP Lite. Earlier I could install XAMPP Lite on external drives only and not XAMPP for Windows. Was it changed and could I install XAMPP for Windows of external drives today too?

4. Exists a search in this forum? It's needed many times to search an answer of my question when I must open all postings.

So that's all.

I hope, I get all answers of my questions.

Thank you all in advance.

With kind regards from Germany
