MsgFiler Filing Script

By default, MsgFiler 4 can perform many actions on Mail, such as opening mailboxes, creating new mailboxes, flagging and labeling messages, and more. If you do not have any Gmail accounts, MsgFiler 4 can also file messages without any help. It does this by communicating with Apple Mail using AppleScript.

It's strongly recommended to install and activate the MsgFiler Filing Script. It brings all the performance and features from previous versions of MsgFiler back to MsgFiler 4 running o n macOS Sonoma!

If you have Gmail accounts, however, MsgFiler 4 needs to perform some extra steps to make sure your emails are filed properly. And unfortunately, MsgFiler 4 cannot perform these steps due to the App Sandbox and Mac App Store restrictions on apps. By installing the MsgFiler Filing Script in MsgFiler 4's dedicated Application Scripts folder, MsgFiler 4 can now send these extra commands to Mail to enable the following:

  • Filing messages to Gmail accounts.

  • Selecting the next/previous message after filing to non-Gmail accounts.

  • Archiving messages from MsgFiler 4.

  • Shortcut actions.

Installation of the MsgFiler Filing Script is covered in the Filing Script section of Onboarding.

The MsgFiler Filing.scpt file will be placed in the following location on your computer:

Scripts run by MsgFiler 4 from this folder are allowed to do so outside of the App Sandbox. Commands for archiving Gmail messages or selecting the next/previous message in the Message Viewer are only available when run outside of the App Sandbox.


Once the MsgFiler Filing Script has been installed and enabled, MsgFiler 4's title bar will change to read MsgFiler + Filing Script.
