On UNIX you can unlink a file while some processes (possibly the same
process) has that file open. Reads, writes, &c. continue to work,
except the file is no longer in the directory tree. The file's inode
is only deleted when all processes close their handles to it. Other
systems don't have that property—deleting an in-use file may fail
(under Windows) or leave the running process in some broken state
(probably some OS operates that way).
On the other hand, various programs' uninstall scripts successfully
delete the entire directory tree, including the uninstaller. Don't
know how they do it.
Hope that helped some,
