Unable to delete the bin directory in Filezilla

In filezilla I used to upload the website contents for our project from today it is showing that you can't delete this directories. But the thing is yesterday only I have uploaded correctly and website also worked correctly.From today it is not displaying correctly and if I trying to delete that bin folder and to upload new one it is showing error 550 Permission Denied.Also I tried to change the file permission to 777 to delete and renaming this dll files within this directory but not used.

This is the error list:

Solution

  • You are likely accessing an FTP server hosted on Windows. On Windows, unlike on Unix, files which are in use cannot be removed. So if the application running your website loaded those DLL files, you first need to make it unload them.

    FileZilla issues a DELE, the FTP server translates this to some kind of unlink command for the OS. The OS refuses to delete the file as it still is loaded. It's not the fault of FileZilla nor of the FTP server.
