Answer 1

You can find the file name before saving.

Railo:

GetPageContext().formScope().getUploadResource("myFormField").getName()

Adobe:

function getClientFileName(fieldName) {
var tmpPartsArray = Form.getPartsArray();
var clientFileName = "";

if (IsDefined("tmpPartsArray")) {
    for (local.tmpPart in tmpPartsArray) {
        if (local.tmpPart.isFile() AND local.tmpPart.getName() EQ arguments.fieldName) {
            return local.tmpPart.getFileName();
            }
        }
    }

return "";
}
