Kill Folder function with persistence
This is a Kill Folder function with persistence ... It will remove all sub-folders and files and then optionally delete the specified folder ... I found when removing all the files in the temp folder that some locked files would fail and cause it to not continue with the rest of the files ... This function will continue to remove all unlocked files, even after finding locked files. However, if locked files are found, the parent folder will also not get removed.
