Repath and Actions Preview windows

Repath window

Lets you change an existing file path to point to a different location.

New path: The directory where Maya looks for files that are being repathed. You can enter a path manually, paste a path into the field, or click Browse to navigate to a new location. By default, New Path is initially set to Maya's current working directory. If you are preparing a scene for use by someone with a different directory structure or platform, you can path to non-existent files.
Note: To repath a reference node, the target file must exist. Unlike other node types in the File Path Editor, you cannot repath references to non-existent files.
Search Subdirectories for Files: When on, Maya searches through sub-directories to the specified New Path until the first instance of the file is found.
Repath Currently Resolved Files: When on, Maya also attempts to repath any resolved files that are included in the selection.
Repath: Performs the repathing operation and closes the Repath window.
Preview: Opens the Actions Preview window. See Actions Preview window.
Cancel: Cancels the repathing operation and closes the Repath window.
