A folder is not a box you put conversations into. It is a filter over the one list you already have — a saved question that the app answers again every time you tap the tab.
That distinction decides whether folders quietly maintain themselves or become a second thing you have to tidy. Most people build the second kind without realising there was a choice.
What you will be able to do after this step
- check_circle Build a folder that fills itself instead of one you maintain by hand.
- check_circle Use the exclusion rules, which are the half nobody touches.
- check_circle Make a tab that empties itself as you deal with things.
- check_circle Decide how many tabs is too many, and what order they belong in.
folder_special Rules fill themselves; lists do not
When you create a folder you can do two different things, and they look almost identical on the setup screen.
You can name specific chats: these fourteen conversations belong in Work. That is a list, and it is frozen at the moment you wrote it. Every new group you join, every new colleague who messages you, is absent until you remember to add it — and nobody remembers.
Or you can describe a category: all groups, all channels, all contacts, all bots. That is a rule, and it keeps working. A group you join tomorrow appears in the tab without you doing anything, because the tab is a question rather than an inventory.
The useful folders are mostly rules with a handful of named exceptions bolted on: all contacts, plus these three groups, minus that one channel. That shape survives contact with a year of use. A hand-built list of thirty chats is accurate the day you make it and misleading a month later, which is how people conclude that folders do not work for them.
filter_alt_off The exclusions are the interesting half
Everybody uses the include side. Almost nobody opens the exclude side, and it is where the folders that actually change your day come from.
You can exclude muted chats, which removes everything you have already decided is not urgent. You can exclude archived chats, which keeps the things you filed away from surfacing. And you can exclude read chats — which is the interesting one, because it turns a static filter into a queue.
A folder defined as "all my contacts and groups, excluding read" contains exactly the conversations with something waiting in them. Deal with one and it leaves the tab on its own. When the tab is empty, you are finished — not in an aspirational sense, but literally: there is nothing in it.
That is the single most useful thing folders do, and it takes about thirty seconds to set up. It also removes the main reason people avoid opening messages, which Step 017 examined from the other direction: a list that empties is much less daunting than a list that only grows.
You delete a folder you no longer use. What happens to the forty conversations that were in it?
Nothing moves when a folder is created and nothing moves when it is deleted. Every conversation lives in one list; folders are saved filters over it, and a chat can appear in several at once. That makes them cheap to experiment with — build one, use it for a week, delete it if it was wrong, and nothing has been disturbed.
Your Work folder lists thirty specific chats. You join a new project group. What appears in the tab?
This is the difference between a list and a rule, and it is why hand-built folders decay. A folder defined as "all groups, excluding these five" picks up the new one automatically; a folder defined as thirty names does not, and you will not notice until you miss something. When you build a folder, ask whether you have described a category or written an inventory.
You add "exclude read chats" to a folder. What is the tab now showing you?
It is a live filter, so a conversation leaves the tab the moment you read it and returns when something new arrives. Pair it with Step 017's mark-as-unread and you have a working queue: read from notifications, open what you can deal with, and flag what you cannot so it stays in the tab until you get to it.

reorder How many, and in what order
The practical ceiling is not the limit the app imposes. It is how many tabs fit on your phone without scrolling, because a tab you have to scroll to find is a tab you will not use.
Four is comfortable. Six is the point at which people start hunting. If you need more categories than that, the honest reading is usually that some of them are archive material rather than daily contexts — and archiving, covered in Step 042, is the better tool for those.
Order matters more than it sounds, because the first tab is what you see every time you open the app. Put the one you want to look at first there: for most people that is people rather than channels. Whatever sits in position one shapes what you attend to, all day, without you ever deciding to.
On a desktop or a tablet the tabs become a rail down the side, permanently visible, which magnifies both the benefit and the cost. That is the width at which folders stop being optional, as Step 007 noted — and also the width where a badly ordered set of eight tabs is most obviously in the way.
group_add Folders you can hand to somebody
A folder can be turned into a link. Somebody who opens it joins the chats in it and gets the folder on their own account, in one step — which is a genuinely good answer to the problem of onboarding a new colleague into eleven different groups.
The part worth knowing is that the link stays connected. Add a chat to the folder later and everybody who joined through it is offered the new one. That makes it a distribution channel rather than a one-off invitation, which is useful when it is deliberate and surprising when it is not.
Two practical cautions follow. Only include rooms you are comfortable inviting people into in bulk, since the recipient joins them as a set rather than choosing. And remember that the folder you share is a snapshot of a category: if the folder is rule-based and picks up new groups automatically, you may be offering people chats you never intended to include.
archive Folders, muting and archiving are three different answers
People reach for folders to fix a chat list that has become unreadable, and folders are frequently the wrong one of the three tools available. They do different jobs and they stack.
Muting answers "this interrupts me". It stops the noise and leaves the conversation exactly where it was. If the complaint is that your phone will not stop buzzing, no amount of folder building helps.
Archiving answers "I do not want to see this". The chat leaves the main list entirely and waits somewhere else. This is the right tool for rooms you are technically in and have finished with — and Step 042 covers the rules that can send things there automatically.
Folders answer "I want to look at one part of this at a time". They do not reduce anything; they slice it. A folder over an unmuted, unarchived list of four hundred chats is four hundred chats with tabs on top.
The order that works is therefore mute, then archive, then folder. Most people do it backwards, build eight folders over an unmanaged list, and conclude the feature does not help — when what they needed was two switches and a clear-out.
help Common questions at this stage
How many folders can I have?
More than is useful on a free account, and more again with Premium, which raises both the number of folders and how many chats each can name. The limit people actually hit is the number of named chats in a hand-built folder — which is another argument for rules, since a rule-based folder can cover hundreds of conversations while naming almost none of them.
Can a chat be in two folders at once?
Yes, and it usually is. Since folders are filters rather than locations, a work group can appear in Work, in Unread, and in a shared folder somebody sent you, all at the same time. There is no conflict to resolve and no primary folder to choose — which also means removing a chat from one folder does not remove it from the others.
Can I change the icon on a tab?
Yes, and it matters more on a desktop where the tabs are a vertical rail of icons rather than words. Choose for distinctness rather than accuracy — at that size you recognise a shape, not a metaphor. On a phone, where the tabs show their names, the icon is decoration and the name is what does the work, so keep names short enough to read without truncation.
Is there a quick way to clear a whole tab?
Holding or right-clicking a folder tab offers to mark everything in it as read, which is the fastest way to reset a folder full of channels you have decided not to catch up on. Use it on the noise folders and never on the people folder, for the obvious reason — it clears the badge without clearing the obligation, and the message is still there, unanswered and now unmarked.
Do folders help with notifications?
Not directly — they change what you see, not what arrives. Notification control is per chat, and the two work best together: mute the noisy rooms so they stop interrupting, then exclude muted chats from your main folder so they also stop appearing. Step 055 covers the notification side, including the exceptions that let a muted group still reach you when somebody replies to you.
What is the simplest set-up worth starting with?
Two folders. One rule-based folder containing contacts and groups but excluding muted chats, as your default view of people. One containing everything with something unread, as your queue. Put the first in position one so it is what you see on opening. That covers the two questions you actually ask when you open the app — who is talking to me, and what still needs me — and it takes under a minute.
