How to pass one Zip file path to another folder throgh webservice

Passing the path to a a web service makes no sense unless this code runs on a local network, and the path corresponds to a well known file share. I've seen many people design apps and test them on one machine where they follow this philosophy only to see it crash and burn when deployed to a web server.

Effectively your options are to only use well known shares (and this opens up all sorts of security nightmares because you have to ensure that your web service has the right permissions for those shares), or to pass the ZIP file across as a series of bytes. If you do this, you may need to chunk the file so that it doesn't crash the service by exceeding the maximum upload limit. Also, as a general rule - when you are accepting files, you should never upload them directly to a central store. Instead, upload them to a staging area. Let a virus scanner check the file in the staging area, and only move it into your central store once it has been thoroughly checked.
