About O&O Software
O&O Software is a German developer of tools for Windows PCs and servers. Its range covers drive imaging and backup, file recovery, secure data deletion, defragmentation and system administration, alongside a handful of free utilities such as the privacy tool O&O ShutUp10.
The company was set up in Berlin in 1997 by Oliver Falkenthal and Olaf Kehrer, whose shared first initial gave the business its name. Its first release, O&O Defrag 1.0, followed in February 1998, and Defrag is still one of its main products, now on version 32. O&O describes itself as a Microsoft Partner and says it has customers in more than 140 countries.
Home users can buy single-PC licences for programs such as DiskImage, Defrag, SafeErase and AutoBackup, or take the ToolBox annual subscription, which bundles 15 tools. Software is delivered as a download, and orders are handled by the reseller Cleverbridge, with prices shown in pounds including 20% VAT for UK buyers. Business customers can choose server editions, starter kits and volume licences.
