Example

<h3>Instructions</h3> 
<p>Create a folder Upload in your C: drive 
<br>Try uploading files using the file upload component and check if the files have been appropriately saved in the Upload folder.</p> 
 
<cffileupload  
    url="uploadFiles.cfm" 
    progressbar="true" 
    name="myupload" 
    addButtonLabel = "Add File" 
    clearButtonlabel = "Clear it" 
    hideUploadButton = "true" 
    width=600 
    height=400 
    title = "File Upload" 
    maxuploadsize="30" 
    extensionfilter="*.jpg, *.png, *.flv, *.txt" 
    BGCOLOR="##FFFFFF" 
    MAXFILESELECT=10 
    UPLOADBUTTONLABEL="Upload now"/>

This example sends user-specified files to the server-side template - uploadfiles.cfm. The template file that you define can use the "upload" or "uploadall" action defined in the cffile tag.

Note: The filefield attribute of the upload action is optional.

Use the destination attribute in the cffile tag to define the location to save the files. For the uploadfiles.cfm code, see cffile action = "uploadAll".
