Why do I sometimes get the default “file conflict” dialog instead of the Classic Explorer replacement?
There are 3 known cases where the “file conflict” dialog is not replaced. • If you copy or move files from a namespace extension to the file system. The reason is that the namespace extension controls the copy operation and may provide any UI it chooses. • On Windows 7 with UAC enabled, if you move a file from a system directory to another directory the operation is carried out by a special protected process called dllhost.exe. Classic Explorer cannot affect that special process. • If you are using a third-party file manager or Explorer replacement. Try unchecking the “Enable only in Explorer” option in the Settings. Depending on the tool you are using, Classic Shell may or may not be able to do something.
