Need help with OReilly File Upload API

I am using OReilly API's to upload files but facing some problems:

1. When two different files are uploaded with one name then its overwrite the previous file

2. Can I change the name of uploaded file before saving on the server

3. I just want to upload zip or rar format. Can I handle this with Orielly API?

4. Any solution to check virus before loading to server?

Thanks & best regards

    1. When two different files are uploaded with one name then its overwrite the previous file

This should not be surprising, unless the API specifically checks for the existence of a file with the same name.

    2. Can I change the name of uploaded file before saving on the server

Without a link to the API documentation it's difficult to know. That said, five seconds on Google led me to this.

    3. I just want to upload zip or rar format. Can I handle this with Orielly API?

Automatically? Sure doesn't look like it: can't you just check the name of the FilePart's file?

   4. Any solution to check virus before loading to server?

Not in the API itself; it's a multipart request parser, not an antivirus solution.
