Mailspring seems to store email attachments under (in Linux, Debian) ~/.config/Mailspring/files. It seems that files stay there even after emails are deleted and also after using “Reset Cache” under the “Local Data” section in the “General” tab of the Preferences.
Is there a way to remove the unnecessary files from within Mailspring?
Extra question: Wouldn’t this be the desired behavior of the Local Data/Reset Cache option?
