Portable software help

[kristinehinojosa]

Hello,

I have some questions about portable software

notepad++ official site does not have portable version https://notepad-plus-plus.org/downloads/
portableapps.com has notepad++ portable version https://portableapps.com/apps/developme ... p_portable
sourceforge.net has notepad++ portable version https://sourceforge.net/projects/portab ... /Notepad++ Portable/

Q1. If I use https://portableapps.com/apps/developme ... p_portable to open/edit/save files does it mean it will not leave any anything in the computer?

Q2. What is the difference between https://portableapps.com/apps/developme ... p_portable vs https://sourceforge.net/projects/portab ... /Notepad++ Portable/

Q3. Is https://portableapps.com safe to use? Is there any similar site like a collection of software portable version so it will not leave anything in the computer?

Q4. Are all the portable software at https://sourceforge.net/projects/portableapps/files/ safe to use and will not leave anything in the computer?

Q5. Is it all portable version of software the purpose is to let you use the software without installing anything and without leaving anything in the computer?
