How can I delete files via FTP on a shared server when FileZilla can't delete them?

I have an hsphere  hosting account on a shared windows server, and I am trying to clean up the files. I see that in 2014 the server was "attacked" and someone deposited many html and ASP files related to spam/malware. I am using FileZilla and trying to delete them, but I get the error :

Command:      DELE shop-celine-handbags-99.jpg
Response:      550 Access is denied.

I can't adjust the permissions on the site because it is a Windows server:

Command:      SITE CHMOD 777 shop-celine-handbags-99.jpg
Response:      500 'SITE': command not understood

I don't have a file manager on the hosting site - it was removed due to "security concerns"

Any suggestions on how to delete the files?

(I don't want to ask the hosting company yet, as I have been "bothering" them a bit too much during the past two days)

the error message you're getting says it all, whatever account you're using does not have DELETE permissions. Unless you have another account with elevated permissions, you're best bet is to contact the hosting company.
