Hello, I am using the fantastic Thunderbird Portable, and also using it effectively as an e-mail database of past e-mails (eg. useful e-mails from past holidays, banking and investment e-mails, etc. These go back quite a few years.

To reduce the size of the Thunderbird Portable system, it would be useful to be able to export specific user folders relating to specific issues - but subsequently be able to import such exported data back into my active Thunderbird system to search/review/add to the data, and then export the folder again.

Possibly related question - is there a maximum size limitation that the Thunderbird system has? My current folder is 1.7GB with 7,500 files.

I make a backup of the folder every few days and keep the previous 10 backups.

Regards, Kevin Cassidy

To import and export folders, try the ImportExportTools add-on. For small numbers of messages, use File/Save As/File (Ctrl-S) to save as eml files; import them by drag and drop into TB.

See the 4th-last 'Changed' item in the release notes about folder sizes.
