KeepandShare builds in a powerful and easy-to-use file uploading capability.
Click on the gray 'Document' tab and then on one of the blue 'Upload Files' commands next to the destination folder name. The Upload Files screen should appear after a few seconds:
You can then:
Choose a file folder from the list on the left (if all you see is "Desktop", then double click on it first).
Check the box(s) in the right window to choose the file(s) you wish to upload.
Lastly, click on the "Upload" button. The files are loaded into the folder where you clicked on 'Upload Files'.
Once a file has been uploaded you can download it again just by clicking on its name.
Note: if you click on the 'Upload Files' command on the blue bar, then the files are uploaded into the very first folder in the Document application.
Note: If the java file uploader does not display within 30 seconds, click the link that says "click here for manual upload". You will then be given an alternative method of uploading your files.
