I had a requirement to delete directories by wildcard. Unfortunately RMDIR User* will not work in command prompt. I found the answer in PowerShell. The following command delete a bunch of folders by wildcard selection.
The following command deletes all folders starting with "2008*" under C:program FilesDBappLogs.
get-childitem -path ‘C:Program FilesDBappLogs’ -filter 2008* | remove-item -force -recurse
The follwoing command deletes all folders starting with anand* under \servernamec$documents and settings
get-childitem -path ‘\servernamec$documents and settings’ -filter anand* | remove-item -force -recurse
If it helps you, I am glad for you.
