Is it correct I need execute-right to change into the directory ?
I notice that when using ftp, I need execute (x) rights to be able to change into the directory.
Then I also need read (r) to see the files inside that directory.
Then finally I need write (w) to be able to delete files in this directory.
This execute (x) right to be able to change into a directory with ftp concerns me in that this makes it also possible to execute scripts and programs.
