On Monday, Microsoft announced the next generation of Office and also made available for download the preview version to the public. Even though Office 2013 is compatible with only Windows 7 and Windows 8, and doesn’t support the good old Windows XP and Vista, thousands of Windows 7/8 users have already enjoying the next Office. While it’s possible to install Office 2013 preview alongside previous Office versions, many interested users are hesitating to install the newest version of Office because of disk space requirements. According to Office 2013 system requirements, a minimum of 3.5 GB of free disk space required to install the newest version of Office. Though one can reduce this minimum disk space requirement by installing only required programs, the web installer doesn’t allow you omit one or more programs during the installation and installs all programs included in the Office setup. Another catch is that the web installer doesn’t allow you change the default installation location and chooses the Windows drive for the installation. So, you must have 3.5 GB of free disk space on your Windows drive to be able install and experience the Office. Users who are interested to explorer the newest version Office and don’t have enough free disk space on Windows drive can follow the given below steps to install Office on a different location other than the default Windows drive. NOTE: If you want to move the Office 2013 installation to another location, refer to our how to move programs and games in Windows guide.
