Quick answer: Use both. Folders give each file one home that other apps understand. Tags describe topics, so a file can belong to several categories without being copied. Keep a shallow folder structure and a small set of useful tags. Tag+ in Productivity Plus Pack adds tagging and indexed search filters to File Explorer.
The question every file system runs into
Where do you save the invoice for the kitchen renovation? In Invoices? In House\Kitchen? In 2026? With folders, you have to pick one — and six months later you'll look in the other two first.
Notes apps like Obsidian and email like Gmail made this debate familiar. On Windows, the same question applies to your documents, photos and projects.
What folders are good at
- Everyone understands them. Every app, every Open dialog and every backup tool works with folders.
- They give a file one home. A project folder keeps everything for that project together, ready to zip, share or archive.
- They're portable. Copy a folder anywhere, and its structure comes along.
Their weakness is that a file can only be in one place. The moment a file belongs to two categories, a folder system forces a choice — or a copy that soon gets out of date.
What tags are good at
- A file can have many. The kitchen invoice can be tagged Invoice, Kitchen and Tax 2026 at the same time.
- They cut across folders. A tag finds every matching file, wherever it's stored.
- They describe, not locate. Status tags like To do or Important work across every project.
Their weaknesses are real too: tags only help if you apply them consistently, and not every app or file type understands them. In Windows, only some file types can be tagged at all — see How to tag PDFs, documents and more in Windows.
Side by side
| Folders | Tags | |
|---|---|---|
| A file can belong to | One folder | Many tags |
| Finding files | Browse to the right place | Filter or search from anywhere |
| Works in every app | Yes | Depends on the app and file type |
| Survives copying anywhere | Yes | Tags stored inside the file do; others may not |
| Effort to maintain | Pick a place when saving | Tag when saving — or let AI help |
| Best for | Where a file lives: projects, years, archives | What a file is about: topics, status, people |
The answer: use both
The most practical system keeps a simple, shallow folder structure for where files live, and uses tags for what they're about. A few habits make it work:
- Keep folders broad: by project, area or year. Resist nesting them five levels deep.
- Start with a handful of tags you'll really use, like Invoice, Important and To do, and add more when you need them.
- Use ratings for quality and tags for topics, instead of tags like Best.
- Let search do the rest: file names, dates, comments and tags are all searchable.
Making tags practical on Windows
Tag+ from Productivity Plus Pack brings tags into File Explorer alongside your folders:
- Tag and rate over 60 supported file extensions — PDFs, text files and archives included — from the right-click menu.
- Every tag gets a one-click filter in Explorer's navigation pane that works like a virtual folder.
- Drag files onto a filter folder to tag them — as quick as moving them into a folder.
- Tag Sense AI suggests tags from each file's content, so staying consistent takes less effort.
