Password Protect Folders

:?:

Hi,

Can anybody help?...

I want certain people to have access to my ftp server and webspace, but is there any way to password protect individual route / top level folders, rather than actual URLs (which I can protect, but all html etc. content is also contained in it's own folder). (and no, I don't have the option to give other users individual ftp pswds).

i.e.

ftp.xxx.xxx

/downloads

/htdocs (all web content in here to which I can pswd protect individual urls contained in this folder)

/other

So for example I may want people to have access to /other, but I don't want them to have access to /htdocs else obvioulsy they could delete the contents etc. etc.

Any ideas?

Cheers
