Fields

FailIfExists 2

Raise an exception of type System.Exception if the file or folder already exists.

Methods that don't explicitly pass a value from the CreationCollisionOption enumeration use the FailIfExists value as the default when you try to create, rename, copy, or move a file or folder.

GenerateUniqueName 0

Automatically append a number to the base of the specified name if the file or folder already exists.

For example, if MyFile.txt already exists, then the new file is named MyFile (2).txt. If MyFolder already exists, then the new folder is named MyFolder (2).

OpenIfExists 3

Return the existing item if the file or folder already exists.

ReplaceExisting 1

Replace the existing item if the file or folder already exists.

Remarks

Methods that don't explicitly pass a value from the CreationCollisionOption enumeration use the FailIfExists value as the default when you create a file or folder.

For example, the CreateFileAsync method has one overload, CreateFileAsync (String, .CreationCollisionOption), that explicitly passes a value from the CreationCollisionOption enumeration. If you call the other overload, CreateFileAsync (String), the method uses the FailIfExists option as the default.
