PutRelativeFile

Creates a new file on the host based on the current file.

This operation works as follows:

1. The WOPI host checks if a file is currently locked or not.
2. If the file is currently locked and the X-WOPI-Lock value does not match the lock currently on the file, the host must return 409 Conflict ("lock mismatch") and include the X-WOPI-Lock response header containing the value of the current lock on the file. In the case where the file is unlocked, the host must set X-WOPI-Lock to the empty string.
3. If the file is unlocked, the host takes the file name from the X-WOPI-SuggestedTarget header and modifies it in order to make the request succeed:
   • If the header contains only a file extension (starts with a period), then the resulting file name will consist of this extension and the initial file name without extension.
   • If the header contains a full file name, then it will be a name for the resulting file.
4. Finally, the host creates a new file that has a legal name and does not overwrite any existing files, while preserving the file extension.

Save Copy As

Starting from version 8.1, the Save Copy As functionality is added to the WOPI protocol through the PutRelativeFile operation. In the ONLYOFFICE Docs API, this action is implemented as the onRequestSaveAs event.

When the PutRelativeFile operation is executed to save a copy of the current file, the X-WOPI-FileConversion header is not sent in the request.

To restrict the Save Copy As functionality, set the UserCanNotWriteRelative property in CheckFileInfo to true.
