Issue with importing a databse into phpMyAdmin

Issue with importing a databse into phpMyAdmin

I am learing how to use SQL. I set up a localhost. In the course of that
journey I was confronted to the issue of importing sql files into
phpMyAdmin. I did the right click on config.inc.php and clicked on the
Notepad++ that I previously installed. I typed in there the following
code: $cfg['UploadDir']='c:\Files'; Of course I created on the hard drive
C the 'Files'. Now that I came back into phpMyAdmin, clicked on my
database, clicked on import, this is what I got as message: "The directory
you set for upload work cannot be reached." Can anyone help me here with
this issue? Thanks.
