In Gmail when you attach a large file to an email, it is uploaded to your Google Drive account instead and the receiver is linked to that location in your Drive.
It is annoying to me that such files are uploaded to the root of my Google Drive (#firstWorldProblems). I would prefer them to always be uploaded to a specific folder. Is there a way to achieve this?
Sign out of Google Drive from the incorrect Google Account.
Attach a file from Google Drive and login to your Google Account to re-authorize Trello's access to your Google Drive.
Yes it's possible, but it's required to extend Google Drive to be able to do so.
Users could authorize apps created by themselves and third party apps to access their Gmail mailbox, like a desktop/mobile email client among others, so it's possible that if the user "lose access to his gmail account" on the web, he still be able to access the messages and the attached files to them.
Google Drive is not a third party app, so if the user "lose access to his gmail account" he could not access Google Drive with that account. Besides this, Google Drive doesn't has a built-in feature to access Gmail messages attachments but it could be extended through add-ons and Google Apps Scripts.

Unfortunately, you can't specify where your attachments will be dropped. Its default behavior to end up in the root folder. The only solution (not fast tho) would be to upload such attachments onto a Drive first and then compose your email where you can select a file from your Drive with utmost comfort.
