Impossible to trash files from a folder which is a symbolic link to a NTFS partition folder
Solution 1:
I have not found any real solution for this but i do have a work around that is slightly less annoying that browsing to the downloads folder on the other partition.. i created a softlink to the Downloads folder in the downloads folder... I know this sounds weird but it does not throw up the error when you go to the 2nd downloads folder and delete something.
So basically this happens: browse to ~/Downloads (which itself is a softlink to the other partition) click on the "Downloads" softlink in that folder (which basically links to itself) now you can delete files without the annoying error. its one extra click but saves browsing the other partition.
