Folders Containing Large Number of Files

An Automation configured on a folder containing a large number of files may experience performance issues or be disabled. The soft limit is 10,000 files per folder. The hard limit is 100,000 files per folder, and when a folder reaches or exceeds that limit, the Automation will fail.

The hard limit applies when the source folder is evaluated through folder matching logic, such as with triggers like interval, custom schedule, or inbound webhook, where files are copied, moved, or deleted from the source folder to a destination. The hard limit does not apply when the Automation uses a file action based trigger.

To keep folders under the limits, use automatic file organization by file extension, creation date, modification date, or regular expression to move files from large folders into subfolders. This produces smaller collections that Automations can process reliably.

Another way to manage file count is the File Expiration folder setting. File Expiration automatically deletes files after they reach a specified age, preventing folders from growing too large over time.
