unable to delete module (permission denied!?)

[weaselweasel]

I installed a module called Cataloger on my CMSMS, by uploading an XML file.
Now I want to clean up, so I'd like to delete the module.
But when I try to delete the files, my FTP client says "550: Permission Denied"!!

So now there are files stuck on my own webspace which I can't get off. It's like not being able to enter your own house 'cause someone changed the locks.
I really don't understand how this is possible. How can I solve this?

You cannot delete files via FTP that has been created via PHP script.
Use the FileManager of CMSms to delete those files.
Activate the advanced options so that you are able to browse outside of the uploads folder.

Ah, thank you!

note to self: don't upload stuff via php system anymore

You should have been able to go to Extensions » Modules then uninstall it there then it should have a Remove link that will remove the folder and all files of the module...
