Answer 1

final String IMAGE_DIR = "${servletContext.getRealPath('/images')}/";

    def employeeId = "dablu_photo";

    def employeePicture = request.getFile("cv_");

    String photoUrl  ="";
    if (employeePicture && !employeePicture.empty) {
        if (new java.io.File(IMAGE_DIR+"/employee_photo/"+employeeId+".png")?.exists()){
            FileUtils.deleteQuietly(new java.io.File(IMAGE_DIR+"/employee_photo/"+employeeId+".png"));
        }
        employeePicture.transferTo(new java.io.File(IMAGE_DIR+"/employee_photo/"+employeeId+".png"))

    }

Answer 2

The destination is only a file like in Java.

def f = request.getFile('some_file')

//validate file or do something crazy hehehe

//now transfer file
File fileDest = new File("Path to some destination and file name")
f.transferTo(fileDest)

OR if you want to store it at some path relative to user home:

def homeDir = new File(System.getProperty("user.home")) //user home e.g /home/username for unix
File fileDest = new File(homeDir,"path/to/some_folder")
f.transferTo(fileDest)

UPDATE As per why your getFile is not working, you are not submitting your form:

<g:form action="list" enctype="multipart/form-data" useToken="true">

<span class="button">                   
                    <input type="file" name="filecsv"/>
                    <input type="button" class="upload"
                                        value="Upload"
                                        onclick='location.href = "${createLink(url: [action: 'upload'])}"'/>

            </span>

</g:form>

Should be:

<g:form action="upload" enctype="multipart/form-data" useToken="true">

<span class="button">                   
                    <input type="file" name="filecsv"/>
                    <input type="submit" class="upload" value="upload"/>

            </span>

</g:form>

if you need to use javascript you should submit the form instead of adding a link to another page.

The location of your Grails app doesn't matter. You have to specify the full destination path in your controller. Here is an example

def upload() {
    def f = request.getFile('filecsv')
    if (f.empty) {
        flash.message = 'file cannot be empty'
        render(view: 'uploadForm')
        return
    }

    f.transferTo(new File('D:\myapp\upload\file_name.txt')) 
    response.sendError(200, 'Done') 
}
