I am trying to upload a file of 70 MB to hotfile file hosting via ftp. But whenever the connection drops or disconnects it says transfer failed and when i tried to upload it again it starts from beginning again . i have ticked on Enable resume support in Advanced tab also. So how to resume the upload as it says that Andftp supports resume upload but how tell me?
"Enable resume support" checkbox seems enabled on your screenshots so it seems fine. If you've clicked "Save" it will taken into account. It may be a problem with FTP server. If you could provide a testing FTP account then we could try to investigate more.
