There is a patch series in progress to add filesize searching, if someone wanted to work through the review issues: id:20170518222708.30032-1-...@adirat.com https://nmbug.notmuchmail.org/nmweb/search/id%3A20170518222708.30032-1-adi%40adirat.com d P.S. #notmuch requires nicks to be registered with services, as an attempt to combat the amount of active spambots. ___ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch

It's quite nice to see the messages in question. Looking at the raw message files is not helpful, as the contents are usually encoded. > So, capturing the results of that with a notmuch tag would be > a reasonable thing to do.

It would be better to have a separate numeric field in xapian similar to how the date is handled. Then the user could search for files of specific sizes. A more usable feature would be to sort the currently selected messages by size in emacs or any other front-end. In the past I've used Thunderbird to archive old/large messages from my imap server. It has a column in the UI that allows you to sort files by size.

Thanks for this, I will use your command for my current needs. Even if notmuch supported a more elegant feature, I would still need to somehow locate and remove the messages from my maildir. I can see how the separation between the xapian database and the maildir makes it impossible to support cleaning up the maildir through notmuch. ___ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch

I imagine that Mark would be more interested in viewing these files to ensure they are what he thinks they are before deleting them. So, capturing the results of that with a notmuch tag would be a reasonable thing to do. The only trick there is that I don't see any existing search term to find a message associated with a particular file name, (we have "path:" and "folder:" to find messages in a specific directory, but nothing I see for finding the message corresponding to a specific file). So, then we could extract the message-id from each file and do a search based on that I guess? Here's a (bash) command I just ran on my mail store of over a million messages that tagged the 8 messages larger than 50MB. It took about a minute to run (with a warm cache): for msg in $( for file in $(find . -type f -size +50M); do grep -i ^Message-Id $file | sed -e 's/^.*<\(.*\)>.*/\1/'; done ); do notmuch tag +large id:$msg; done With that, I'm able to go through the list from: notmuch search tag:large to investigate whether these large emails are worth keeping. So, that's obviously not extremely elegant, but it's at least possible. -Carl signature.asc Description: PGP signature ___ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch

finding file by size
Is there a way to use notmuch to optimize space in my maildir? I'd like to find and delete the dozens of messages that were sent to me years ago with 50MB attachments. I didn't see a search-term that returns results by size. I tried to ask this on #notmuch, but got: *** #notmuch: Cannot send to channel thanks, Mark ___ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch
