Importing files from the user's computer is a little more complicated than creating an empty
file. You need to create a FileEntry and then write the contents of the imported file to the
FileEntry using the File Writer API.

In addition, because you added the multiple attribute to the File Browser Import form,
...< form name = "import" >
< div >
< h2 > Import existing file ( s )</ h2 >
<input type= "file" name= "files" multiple accept= "text/html" >
< input type = "submit" value = "Import" >
</ div >...

menting this isn't difficult, the validation process becomes more complicated, as you'll see.
Copy the following code, and insert it right after the event listener you added to the create
form in the previous section.
