Commands : RenameAsync

RenameAsync is used to change the file name.

Syntax

Task RenameAsync(string currentName, string newName, Etag etag = null);

Parameters
currentName string The name of the file that you want to change
newName string The new name of a file
etag Etag The current file etag used for concurrency checks (null skips check)

Return Value
Task A task that represents the asynchronous rename operation

Example

await store
	.AsyncFilesCommands
	.RenameAsync(
		"/movies/intro.avi",
		"/movies/introduction.avi"
	);

Note that a file move operation is basically the rename too (directories are just a virtual concept). In order to move intro.avi file from /movies folder to /movies/examples, we need to use the following code:

await store
	.AsyncFilesCommands
	.RenameAsync(
		"/movies/intro.avi",
		"/movies/examples/intro.avi"
	);

Rename on the server side

If the file rename is requested, RavenFS needs to update collection of usages of this file's pages. In order to make RavenFS resistant to restarts in the middle of the rename operation, use a a periodic task, which ensures that all requested renames will be finished after the restart.
