Duplicate mail volume in GMail when connected via IMAP

Question

Google

Hello.

GMail somehow treats free users in a strange way, without providing absolutely no way to contact technical support, except through a public “complaint book”, where a lot of people write, and only a few receive an answer. At least the help page only takes me there and nowhere else. I cannot get a PIN for a call due to the use of free Google Apps services.

Now working mail is hanging on Google Apps, however, due to an old jamb, which for some magical reason no one has yet fixed, the mailbox is 99% full and the mail almost does not work.
Let me explain: as far as I know, in GMail all folders are Inbox, Sent Items, Trash, Spam, etc. are virtual folders, i.e. links to email categories from the All Mail public folder. And if, while working in an email client configured to work via IMAP, I turn on the “Display in IMAP” option for the “All Mail” link on GMail, all mail from GMail will be downloaded again into Thunderbird into the new “All Mail” folder, and why should GMail - it will duplicate all letters in "All Mail" already in the form of real folders. In other words, in GMail, instead of one folder "All Mail" and links from it that do not take up space to virtual folders "Inbox", "Sent", "Trash", "Spam", etc., it will actually create these folders and re-copies letters from All Mail into them, i.e. will duplicate the contents of already received mail and will duplicate all incoming mail in the same way, scoring the place twice as fast. And the most annoying nonsense is that even after setting all this nonsense into a human form (disabling all IMAP links, except for the main ones), I didn’t have any more space at all! Now there are absolutely no duplicates, I checked all the letters left after the global cleaning and cleaning of the "Recycle Bin" with "Spam" several times - they, in principle, cannot occupy 10GB, this is nonsense, i.e. it jumped somewhere and the place was not cleared, but I can’t do anything else and I didn’t find solutions on the Web either, but I found a bunch of people who suffered from the same problem and also didn’t solve anything, and in order to call Google, I need to buy paid account, otherwise - write letters and do not wait for an answer. I didn't have any space at all!

Question: can I do something in this case, like some kind of purge of deleted files or something else, so that the system sees and returns free space to me? I have already begun to think about transferring mail to the Yandex platform, because. there are no such problems, and now this is the most important thing.

Answer 1

In fact, "folders" are just labels on letters. And even deleting the "folder" you just remove the label from the letter.
What do you have in [Gmail]/All Mail? Are there duplicates? Everything that can be transferred to [Gmail] / Trash, and then deleted from there. Will the free space change after that?

What's the problem with paying $5, becoming a paid user and contacting support?
