## Unable to use the working folder '%very long path%'

### Symptoms

Error "Unable to use the working folder %very long path%" when starting a workflow.

### Cause

The error occurs due to the path length limitation in Windows.

### Resolution

In order to bypass the path length limitation, it is necessary to add the "\\?\" prefix to the path.

Example: «\\?\D:\very long path»

The "\\?\" prefix can also be used with the network path. To specify a network path, use the "\\?\UNC\" prefix.

Example: «\\?\UNC\machinename\sharedfolder»
