The .contentsofclipboard file extension is used by Microsoft's WinXP PowerToy utility, also known as Tweak UI. Tweak UI provides controls for changing various hidden or advanced settings in the Windows operating system.
A CONTENTSOFCLIPBOARD file is associated with Windows Clipboard data used by the utility. It is a supporting data file rather than a general-purpose document format.
The WinXP PowerToy was designed for Microsoft Windows XP and is no longer maintained as a current Windows utility. The format is therefore legacy and is unlikely to be used by modern software.
Open the file with the WinXP PowerToy that created it, where possible. CONTENTSOFCLIPBOARD files are supporting files for the utility and may not be intended to open as independent documents.
Because the PowerToy was designed for Windows XP, it may not work correctly on newer versions of Windows.
CONTENTSOFCLIPBOARD files are supporting files for the WinXP PowerToy rather than documents with a standard export process. No conversion method is specified for this format.
