Organize
Your Files.

Why download any other software to organize files when your browser can do it better? SmartFiles keeps everything private by running the File Organiser locally, with no install, no account, and no uploads.

Yes. The File Organiser runs entirely in your browser using the File System Access API. Your files never leave your device and nothing is uploaded to a server. A 'dry run' preview shows you exactly what will be moved before you confirm anything.

The in-place organizer requires a Chromium-based browser (Google Chrome or Microsoft Edge) because they support the File System Access API. In Firefox and Safari you can still select a folder, preview the plan, and save a re-organized ZIP copy of your files instead. On Android, Chrome protects system folders such as Downloads, DCIM and Documents, and in-place moving is blocked there — pick a folder you created or use the 'Save organized ZIP' button, which works with any folder.

Instead of making a separate folder for every extension, files are grouped into human-friendly categories. For example JPG, PNG, WEBP and GIF all go into an 'Images' folder, while PDF, DOCX and XLSX go into 'Documents'. This keeps your folders compact and easy to scan.

Yes. Switch the sorting mode to 'Date' to create folders by year (2026) or year-month (2026-09) based on each file's modified date. You can also enable 'Group by date' alongside category sorting to nest date folders inside each category folder.

When duplicate detection is enabled, files with the same name and size are moved into a 'Duplicates' folder instead of being copied over each other. The tool never deletes anything—you can review the duplicates folder and remove the copies yourself afterwards.

Yes. Add custom keyword rules like 'Invoice' to route matching files into a folder of your choice, for example a 'Billing' folder. Keyword rules take priority over the automatic category, extension, or date sorting. Your custom rules are saved in your browser for next time.

No. All scanning, planning, and moving happens locally in your browser tab. SmartFiles has no access to your folders and we cannot see, store, or analyze any file names or contents you choose to organize.

Yes. It is completely free, with no sign-up, no account, and no file limits. Organize as many folders as you like.

Because the tool groups by the date a file was last modified, which is a reasonable default but is not the same as when the file was created or when a photograph was taken. A photo downloaded from an email in March may have been taken the previous summer, and a document re-saved after a small edit moves to the top of a modified-date sort on a day when nothing of substance changed. For photo libraries in particular, this is the difference between a folder organised chronologically and one that appears random.

Combining rules usually produces a more useful structure than a single one. Grouping by type and then by year gives a filing system you can navigate without opening anything, and it is far more practical than either dimension alone. You can enable date grouping alongside category sorting to nest date folders inside each category folder, and your own keyword rules take priority over the automatic categories.

Two levels is generally the point where structure stops being helpful and starts being fussy, because beyond that people stop maintaining the arrangement, and a filing system nobody maintains is worse than a simple one. It is also worth choosing group names that sort sensibly, since leading zeros and consistent date formats make a folder listing read chronologically rather than alphabetically.

No. It works purely from each file's own properties, which is its name, its size and its last modified date, and that is why keyword rules like 'Invoice' match against the filename. It cannot tell what is inside a document, so it cannot sort by anything other than the file's own properties. This is also why it is fast, and why it can handle a large folder without waiting on anything.

A duplicate is a file whose name and size match a file already seen in the folder. The first one keeps its place and every later match is separated into the Duplicates folder rather than being copied over an existing file. The tool never deletes anything automatically, because two files sharing a name and a size are not reliably the same file and deleting the wrong one is not a recoverable mistake. A folder that is both well organised and largely duplicates is usually an easy way to free a substantial amount of space.

Nothing is overwritten. If a name is already taken in the destination folder, a counter is appended, so report.pdf and report (1).pdf can coexist rather than one silently replacing the other. The preview shows the exact names that will be created, which is the place to catch this before anything moves.

An empty category usually means a rule did not match what you assumed rather than an absence of files. Switch the sorting mode and re-check the preview, which shows exactly which files would go where and in what order, and add a custom keyword rule for anything the automatic categories miss. Reviewing rather than assuming is the habit worth building in, particularly in a large collection.

No. It has no access to cloud storage, and custom folder rules configured in your operating system are not imported. It works on the folder you hand it, using the rules you set in the tool, with your own keyword rules saved in your browser for next time.
