Convertir .xls or .doc files to formats .xlsx ou .docx

Sometimes you see Office files with old extensions. They are from Office version 97-2003 and have become out of date.
Extensions like .xlsx or .docx replaced these extensions and allow new features, plus smaller files ! 

If you are using NetSync, please prefer these new extensions. More information here !
