Update-FormatData reloads the formatting data from formatting files into the current session. This cmdlet lets you update the formatting data without restarting PowerShell.

Without parameters, Update-FormatData will reload the formatting files.

Formatting files are text files in XML format with the format.ps1xml file name extension. The formatting data in the files defines the display of Microsoft .NET Framework objects in the session.

When PowerShell starts, it loads the format data from the formatting files in the PowerShell installation directory ($pshome) into the session. Use Update-FormatData to reload the formatting data into the current session without restarting PowerShell.

Examples
