Thanks for this great tool! Very helpful.

Is it somehow possible to deactivate the backup function?

This is a fantastic utility! I got a "Mailbox almost full" message yesterday. Using this add-on I was able to free up 10% of the storage in a few minutes' time.

A couple of glitches: The "Over 100 messages" popup just stays there, so don't select over 100 messages. The deleted attachments are stored in a BulkAttachmentBackup folder in the last selected Thunderbird default save folder, even if you've told TB to ask you every time.

None of this dampens my enthusiasm for this utility. I'm going to delete more attachments right now!

Edit: @hurokume, is there a way to email you or send you a screen grab? I am walt@toolworks.com.

And re @RobertOttomar's suggestion, rather than deactivating the backup function, each time the utility finishes move the BulkAttachmentBackup folder to the Recycle Bin, where it can be retrieved if desired?

Thanks so much for the detailed feedback — I’m really glad to hear the utility helped you free up space so quickly!

I tried it on my own laptop as well and found the same bug you mentioned. I’ll work on a updating, but it might take a little time, so please give me a time to fix it (^^)
