Your files are not in E://xampp
The name of the bat file is setup_xampp.bat.
readme_en.txt wrote:* QUICK INSTALLATION:
[NOTE: Unpack the package to your USB stick or a partition of your choice.
There it must be on the highest level like E:\ or W:\. It will
build E:\xampp or W:\xampp or something like this.Please do not use the "setup_xampp.bat" for an USB stick installation!]
What do you not understand?
It clearly states the xampp folder is built in the highest level of a drive (the root) and you do not to put the files from the xampp folder into the root of the drive.
Nowhere does it suggest you move the files out of the xampp folder.
I believe you will have many more issues with a web server if you can't understand simple installation steps.
I will close this topic as your question has been answered.
