Copying files between different SharePoint libraries with custom metadata

You might have a requirement to move sample files from a site to a different site, e.g. subset of production files to UAT site to allow testing of solutions. You may want better control over metadata settings, such as ProcessStatus, ensuring files are marked as "Pending" upon transfer . Unlike the default file copy feature, this script enables you to skip the copy process if the destination site lacks a matching folder structure as well setting custom metadata to specific values.
