@engler @kaia nah it is inodes.

internally the path is just an abstraction layer to make it human readable and for scripts and co to know where to go. but the actual folders are not identical

works also in /home
Terminal A:
cd /home/user/removeme
/home/user/removeme/testfile


Terminal B:
other terminal
rm -r /home/user/removeme
mkdir /home/user/removeme
touch /home/user/removeme/testfile


Terminal A:

ls

will return nothing.
first the content got deleted but the terminal A is still in the first folders inodes.
though a simple "cd ." will load the new content of the path
