Applies to Windows and Windows Phone

Specifies what to do if a file or folder with the specified name already exists in the current folder when you create a new file or folder.

Syntax


var value = Windows.Storage.CreationCollisionOption.generateUniqueName;

Attributes

[Version(0x06020000)]

Members

The CreationCollisionOption enumeration has these members.

MemberValueDescription
GenerateUniqueName | generateUniqueName0

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).

ReplaceExisting | replaceExisting1

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

FailIfExists | failIfExists2

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.

OpenIfExists | openIfExists3

Return 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.
