If a file is locked by other user/application, file mutation might fail with errors like below:
{"code":40073,"data":[{"path":"cloudreve://my/newdfox.docx","token":"cool-lock0a4b4f68","owner":{"owner":"bnUn","application":{"type":"viewer","viewer_id":"af01b85b-f57d-46d2-8ad6-1d9b96548e78"}},"type":0}],"msg":"Lock conflict","error":"conflict with locked resource: \"cloudreve://my/newdfox.docx\"","correlation_id":"64210cda-5bd1-4fe1-9102-77b86f768395"}
The lock token cool-lock0a4b4f68 in above example is only visable to file owners. This method can be used to force unlock files if the file owners wish to do so.
