Tags, folders or links? How to organize notes you can find again

How to organize notes you can find again: when to use folders, tags or links, a starter tag set, naming rules and a simple 10-minute weekly review.

A capybara in a cozy study holds a small stack of index cards, deciding where to put one among a wooden card-catalog cabinet, shelves of unlabeled boxes and a corkboard of cards connected by threads.

The best way to organize notes is to use each tool for one job. A shallow set of folders or top-level tags says where a note lives, a few tags say what it is about, and links connect ideas that belong together. Search does most of the actual finding, so the structure only needs to be simple enough that you keep using it.

This guide explains how to organize notes in any app, when tags beat folders (and when they don't), what backlinks are really good for, and a starter tag set you can copy today. A short section at the end shows how the same ideas work in Cappa, our app.

What does organizing notes actually mean?

Good digital note organization has one goal: to find a note again when you need it, ideally within seconds and without remembering exactly how you filed it. Organizing for its own sake is not the point. Any structure that costs more time than it saves is decoration.

Research on how people find their own information points the same way. In a field study of 345 email users and more than 85,000 attempts to find old messages, Whittaker and colleagues (CHI 2011) found that people who built complex folder trees did rely on them, but the effort did not make them more successful at finding things; search and conversation threads worked better. A study of files on personal computers by Bergman and colleagues (2010) found folders working well: people found 94% of the files they looked for by browsing, and those files sat only about three folders deep on average.

Put together, the lesson is modest and practical. A shallow structure you can browse is helpful. A deep, elaborate one mostly costs you time. And search is not a fallback; it is the main way you will get back to most notes.

Folders: one place for each note

A folder works like a drawer. Every note sits in exactly one drawer, and you find it by opening the right one. Most people already think this way from their computer's file system, so folders need no explanation.

Folders are good at three things:

  • Browsing. You can open "Recipes" and see every recipe without typing anything.
  • Clear boundaries. A note is either in "Work" or it isn't.
  • Portability. Folders map to plain directories on disk, so they survive a move to another app.

The trouble starts with notes that belong in two places. Is the plumber's quote for your bathroom a "Home" note or a "Money" note? You pick one, and six months later you look in the other. People react by creating deeper folders ("Home/Renovation/Quotes"), which makes each decision harder, or by copying the note, which leaves two versions that drift apart.

The "where do I put this?" problem

The moment of hesitation when a new note fits more than one folder. It is small each time, but it happens with almost every note that matters, and it pushes people to stop filing altogether.

Tags: many labels for one note

A tag is a label you attach to a note, usually written as a word with a hash sign in front, like #recipe or #money. Unlike a folder, a note can carry several tags, so the plumber's quote can be both #home and #money, and it shows up in both lists.

Many apps also support nested tags, written with a slash: #home/renovation is a child of #home. This gives you some of the tidiness of folders (a tree you can browse) without forcing each note into a single branch.

Tags have their own failure mode, usually called tag sprawl. Without rules, you end up with #book, #books, #reading and #to-read, all meaning roughly the same thing. Each tag then holds a fraction of the notes it should, and browsing by tag stops being reliable. The fix is a few conventions, covered below.

Linking notes: connecting one idea to another

A link points from one specific note to another. In many Markdown note apps you write it as the other note's title in double square brackets, like [[Monthly budget]]. This is often called a wikilink, because the syntax comes from wiki software such as the one behind Wikipedia.

Backlink

A link seen from the other end. If your note "Plumber's quote" links to "Monthly budget", then "Monthly budget" has a backlink from "Plumber's quote". Apps that show backlinks list every note that points to the one you are reading, so you never have to add the reverse link by hand.

Links answer a question that folders and tags cannot: which specific notes belong together, and why. A tag says "this is about money". A link says "this quote changes that budget".

Backlinks are useful, but they have limits. Sascha Fast of zettelkasten.de argues that an automatic list of backlinks shows only titles, not the reason for each connection, so following them can turn into aimless clicking. His point is worth keeping: the value is in the sentence you write around a link ("this quote is 20% over the renovation budget, see [[Monthly budget]]"). A backlinks panel is a good way to rediscover those sentences, not a replacement for writing them.

FoldersWhere does this note live?

Renovation/

  • Plumber's quote
  • Tile ideas
  • Renovation timeline

Money/

  • Monthly budget
  • Loan rates

The quote belongs to the renovation and to your money, but a folder holds it in one place only.

TagsWhat is this note about?

  • Plumber's quote#home/renovation#money
  • Tile ideas#home/renovation
  • Renovation timeline#home/renovation
  • Monthly budget#money
  • Loan rates#money/loans

The quote carries two tags, so it appears under both. Nested tags keep related labels together.

LinksWhat does this note connect to?

  • Plumber's quotelinks to: Renovation timeline, Monthly budgetlinked from: Renovation timeline
  • Tile ideaslinks to: Renovation timelinelinked from: nothing yet
  • Renovation timelinelinks to: Plumber's quotelinked from: Plumber's quote, Tile ideas
  • Monthly budgetlinks to: nothing yetlinked from: Plumber's quote, Loan rates
  • Loan rateslinks to: Monthly budgetlinked from: nothing yet

Links record which notes belong together. Backlinks are the same links, seen from the other end.

The same five notes organized three ways. Folders force the plumber's quote into one place, tags let it appear in two, and links record exactly which notes it relates to.

Tags vs folders: which should you use?

For most personal notes, tags are the better default and links are the best addition. Folders win when your notes really do fall into separate, non-overlapping groups, or when you need them to match a directory on disk.

Folders work well when

  • each note clearly belongs to one group (clients, courses, years)
  • you want to browse more than search
  • you sync notes as plain files to other tools
  • you keep the tree shallow, two or three levels at most

Tags work well when

  • notes often fit two or more topics
  • you look notes up by topic, status or person
  • you want to regroup notes later without moving them
  • you keep a short, agreed list of tags

Here is a quick decision rule you can apply to any new note:

  1. Does it have exactly one obvious home? Put it there (a folder, or one top-level tag).
  2. Will you look for it in more than one way? Add a tag for each way, but only tags you already use.
  3. Does it change, explain or depend on a specific other note? Link to that note, and write half a sentence about why.

A starter tag set you can copy

Start small. Five top-level tags cover most personal notes, and you add nested tags only when a branch gets crowded.

#work        #work/meetings   #work/projects
#home        #home/renovation #home/recipes
#money       #money/taxes     #money/loans
#learning    #learning/books  #learning/courses
#people      #people/family

Plus one status tag you actually act on, for example #todo or #waiting, if your app doesn't already have a task view.

A few naming conventions keep this set tidy:

  • Lowercase, one spelling. Choose plural or singular once (#recipes, not sometimes #recipe).
  • Hyphens for multi-word tags. #side-project works in almost every app; spaces often don't.
  • Topics, not dates. Your app already records when a note was created and changed. A #2026 tag usually duplicates that.
  • Nouns over adjectives. #taxes groups notes; #important quietly grows until everything is important.
  • Nest by "is a kind of". #learning/books is a kind of learning. Don't nest unrelated ideas just to save space in the sidebar.

How many tags is too many?

There is no scientific limit, so treat these as rules of thumb rather than research. If you cannot list your top-level tags from memory, you have too many. If a tag still holds only one note after a month, merge it into a neighbor or delete it. And if a note needs more than three or four tags, it is often two notes that want to be split.

A worked example in Markdown

Here is what a well-organized note can look like in plain Markdown. Nothing here is app-specific except the double brackets, which most Markdown note apps understand.

# Plumber's quote: bathroom, September 2026

Quote from the plumber after the site visit on September 24.

- Replace pipes under the sink and shower: 1,450
- New shower valve: 380
- Total: 1,830, valid for 30 days

This is about 20% over what [[Monthly budget]] allows for the
bathroom, so the tiles in [[Tile ideas]] may need to wait.
Next step is on [[Renovation timeline]].

#home/renovation #money

Notice four things. The title contains the words you would search for later ("plumber", "quote", "bathroom") plus a date. The links sit inside sentences that say why they are there. There are only two tags, both from the starter set. And the whole note is readable in any text editor, even without the app. If Markdown is new to you, our beginner's guide to Markdown for notes covers headings, lists and links in a few minutes.

Capture first, organize later

Many people give up on notes because every new note demands a filing decision. Separate the two jobs. When an idea arrives, write it down immediately with a rough title and no tags at all. That is capture.

Organizing happens later, in a batch, when you have a few minutes and a calmer head. Untagged notes act as your inbox: anything without a tag is a note you haven't looked at properly yet. Many apps can show all untagged notes in one list, and if yours can't, a single #inbox tag does the same job.

Write titles that search can find

Because search is how you will find most notes, titles matter more than tags. A good title is the phrase you would type into the search box six months from now.

  • Specific nouns. "Plumber's quote: bathroom" beats "Quote" or "Notes 3".
  • Dates in a sortable form for anything tied to time: "2026-09-24 Team meeting: budget". Year first means titles sort in time order.
  • The same word for the same thing. If you call it "renovation" in one title, don't call it "remodel" in the next.
  • One idea per note where you can. A note titled "Misc" is where information goes to be lost.

Learn your search's small powers too. Most apps can search for an exact phrase in quotes, and many can filter by tag or exclude one. Those two tricks make even a loosely organized collection easy to navigate.

A 10-minute weekly review

A weekly review is the habit that keeps any system from decaying. Set a recurring reminder and go through the same steps each time:

  1. Empty the inbox. Open your untagged notes (or #inbox) and give each one a better title and one or two tags. Delete what no longer matters.
  2. Add links. For each note you just processed, ask: which existing note does this change or explain? Link it, with half a sentence of context.
  3. Prune tags. Look for near-duplicates (#book and #books) and merge them. Rename rather than add.
  4. Archive the finished. Move notes about completed projects out of your active lists, so what you see is what you are working on.

Ten minutes is enough when you do it every week. If you skip a month, expect half an hour, which is still far less than hunting for lost notes.

How to organize notes in Cappa

Cappa has no folders. Organization is built on tags written inside the note, plus links:

  • Inline tags. Type #recipes anywhere in a note. Nested tags use a slash (#home/renovation), and a tag with spaces is closed with a second hash, like #side project#. Tags appear as a tree in the sidebar, where you can pin a tag to the top or give it an icon.
  • Parent tags include their children. Opening #home also lists notes tagged #home/renovation, unless you turn on "Hide Subtag Notes" in the list menu. Renaming a tag in the sidebar rewrites it in the notes that use it, subtags included.
  • An inbox for free. The "Untagged" view lists every note without a tag, which makes it a ready-made inbox for your weekly review. There are also "Pinned", "Todo" and "Archive" views, and archived notes leave your tag lists.
  • Search with filters. The search box accepts "exact phrases", #tag (which includes subtags), -#tag to exclude a tag, and @todo, @pinned or @untagged. Press Ctrl+K (⌘K on a Mac) to jump to a note, tag or view by typing part of its name.
  • Wikilinks and the Links panel. Write [[Note title]], or [[Note title#Section|label]] to point at a heading with your own label. Clicking a link to a note that doesn't exist yet offers to create it. The "Links" tab in the note details shows "Links to this note" (backlinks) and "Related by tags": notes that share a tag or a parent tag with the current one and that you haven't linked yet. Those suggestions are computed on your device.
  • Coming from folders. When you import from Obsidian or Bear, Cappa turns each note's folder path into a nested tag, so a note from Work/Projects arrives tagged #Work/Projects. The original files are not changed.

Cappa keeps notes as Markdown, so tags and links stay plain text you can read in any editor after export. For tables, task lists and diagrams inside notes, see Markdown beyond the basics.

FAQ

Is it better to use tags or folders for notes?

For most personal notes, tags are more flexible because one note can carry several labels, while a folder holds it in one place only. Folders are better when your notes fall into clearly separate groups or must match files on disk. Many people combine them: a few broad folders or top-level tags, then tags and links inside.

How many tags should I have?

There is no fixed number. A practical rule is that you should be able to list your top-level tags from memory, often five to ten. Merge tags that mean the same thing and delete any tag that still holds a single note after a month.

A backlink is a link seen from the note it points to. If note A links to note B, B shows A as a backlink, without you adding anything to B. Backlinks help you rediscover related notes, but they are most useful when the original link sits in a sentence explaining the connection.

Should I reorganize all my old notes?

Usually not. Apply the new structure to notes as you touch them, and let search handle the rest. A big one-time reorganization tends to take a weekend and then drift, while a weekly review keeps things tidy with little effort.

Are Zettelkasten or PARA better than tags and folders?

They are systems built on top of these tools, not alternatives to them. PARA sorts notes by how soon you need them, and a Zettelkasten links small idea notes to each other. Our guide Zettelkasten vs PARA, explained simply compares them and suggests a simple way to combine both.
