how to delete the files uploaded in the file field? if i remove the files that were uploaded in a File field,and then upload a same name file, the file removed just now is still present in the server and the new uploaded file gets renamed to a name with index ,say, xxx_0 ,xxx_1.

What I want to do is when I remove a file, it should be deleted from the server, to save space in the server, How can I do this?
I also crossed this issue.
I just did these following steps.


edit the node, and delete the file from the field (dont upload now) and save it.
then edit the node, now upload the file (with same name) and save it.


Its worked for me. without xxx_0 like that.

Thanks
