# Check Files Locked ### Description The `Check files locked` action loops over a list of files to check if they are locked by another process. The way that it verified is by renaming a file to the same name as before. On certain operating systems (MS Windows systems in particular) this operation will fail if the file is locked. ### Options | Option | Description | | ---------------------------------------- | -------------------------------------------------------------------------------------------------------------- | | Action name | The name of the workflow action. | | Settings: Include subfolders | Enable this option to also check files in subfolders of specified folders | | Settings: Copy previous results to args? | Pass the result rows of a previous workflow action execution to the files list of this action. | | Files/Folders | The files or folders to check. | | Wildcard | The wildcards are Java Regular expressions. For instance .\*\\.txt would check any file with a .txt extension. | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
