The '~' is called a tilde, which may help with your search for help. Generally, files with the tilde are temp/backup files. Here's a link to a microsoft page describing them: http://support.microsoft.com/?kbid=211632 These files are automatically created. Make sure you have permissions for the directory you are using. Also, make sure you have registered your Excel program with Microsoft.

Lost Excel file can be recovered from:

1. Recycle Bin - If you have deleted the file with normal delete.
   
2. Backup - If have maintained the backup of file.
   
3. Email - It may possible that you have mailed the file to someone.

The files extensions you have listed, .docx and .xlsx, are files that have been created using the Microsoft Office 2007 or 2010 suite of programs. Specifically .docx is a Microsoft Word document, and .xlsx is a Microsoft Excel spreadsheet. You will have to have either of the Microsoft Office programs mentioned, or you can also use the Open Office suite of programs. This is a free program that you can download at the following website:
