Excuse my ignorance, but isn't every directory deletable?– boehjMay 7, 2011 at 4:41

I'm not sure this is possible O.o– RolandiXorMay 7, 2011 at 4:54

@boehj Only the main directory should not be deletable, all the other sub directories can be deletable.– karthick87May 7, 2011 at 5:08

I won't delete this as it's a valid question that has accurate and acceptable answers.– Oli ♦Jun 26, 2011 at 15:18

Since you want a non removable dir, where you can create, paste, write and delete files you need to set the parent of this dir with non-writable permissions, and the dir with writable permissions. just as above, but taking consideration of group and everyone:
~$ mkdir -p parent/mydir
~$ chmod 755 parent
~$ chmod 777 parent/mydir
This wont let mydir to be deleted for everyone but you. And will let create and delete files within mydir, since this one has write permissions for everyone.
To prevent a directory to be deleted, its parent should be non writable:
enzotib@host:~$ mkdir -p parent/child
enzotib@host:~$ chmod -w parent/
enzotib@host:~$ rmdir parent/child/
rmdir: failed to remove `parent/child/': Permission denied
enzotib@host:~$
