| Config Directory | Blank           | No       | By default, CopyStorm will look for configuration file overrides in the directory “config” within the CopyStorm installation directory. If this value is set then CopyStorm will also look in this directory for configuration file overrides.                                                                                                |
| Temp Directory   | Blank           | No       | By default, CopyStorm will store temporary files containing Salesforce Files and Attachments in the default Java temporary directory. If this value is set then CopyStorm will instead store temporary files in the provided directory. Note: If large files are being downloaded from Salesforce, this directory can become many GB in size. |
