Where Does Claws Mail Store Profiles and Mail?

Claws Mail .claws-mail profile dir with accountrc and Mail folders on Windows and Linux.

Last updated

Claws Mail keeps accounts (accountrc), settings and local Mail folders in a .claws-mail directory in your home folder on both Windows and Linux. MH format means each message is its own numbered file.

That layout makes backup trivial and grep friendly. Copy the folder with Claws closed; the .claws_cache files inside rebuild themselves.

Where Claws Mail stores this, by platform

Windows
%USERPROFILE%\.claws-mail

accountrc plus Mail subfolders at the root. Some builds use %APPDATA%\Claws-mail instead; the one holding accountrc is live.

Linux
~/.claws-mail

Same layout. Each message is a separate file, so rsync and version control work unusually well here.

Frequently asked questions

How do I migrate Claws Mail to a new PC?

Copy .claws-mail to the new home folder with Claws closed. Passwords may need re entry depending on the secret backend.

Can I search Claws mail with grep?

Yes. MH one file per message plays nicely with grep and ripgrep across the Mail tree.
