Tidy the Downloads folder without losing anything
· 6 min read
Open Downloads in Finder, switch to list view and sort by size. Nearly all of the space will be in a handful of disk images, archives and videos you have not touched since the day they arrived. Clear those first, then work through the rest by date rather than file by file.
The folder is worth reading before you empty it. On most Macs it is a mix of throwaway installers and a few things somebody saved once and never moved anywhere sensible.
See what is actually in there
Press Option-Command-L in Finder to jump straight to Downloads, then set the window up so it tells you something:
- Press Command-2 for list view.
- Press Command-J for View Options and turn on Calculate all sizes, plus the Date Added and Date Last Opened columns.
- Click the Size column header to sort largest first.
Calculate all sizes matters more than it sounds. Without it, folders show a dash instead of a size, and the biggest item in a Downloads folder is very often an extracted folder sitting next to the archive it came out of, both of them full size.
Press Command-/ for the status bar too. Item count and free space at the bottom of the window gives you a before-and-after reading that is more honest than a feeling.
If you want one number before you start, Terminal has it:
du -sh ~/Downloads
The four categories that are almost always safe
Most of a heavy Downloads folder is made of four things, and all four can be downloaded again.
Disk images. Every .dmg you mounted to install an app is probably still sitting there at full size. Once the app is in your Applications folder, the disk image has no further job. Eject any that are still mounted in the Finder sidebar first, then delete them.
Installer packages. The same logic applies to .pkg files. They are the delivery van, not the furniture.
Archives you already extracted. If project.zip and a project folder are both present, you are storing the contents twice. Keep the folder, delete the zip, unless the zip is the thing you need to forward to somebody.
Duplicates from repeated downloads. Files ending in (1), (2) or copy are the ones you downloaded again because you could not find the first one. Sort by name and they line up next to each other. If the folder is large enough that this is not practical by eye, finding duplicates without deleting the wrong copy covers doing it properly.
Everything older than six months, in one view
The long tail is where people give up. A saved search handles it without you deciding one file at a time.
- With a Downloads window open, press Option-Command-N for a new smart folder.
- Click Downloads in the scope bar so the search covers that folder rather than the whole Mac.
- Click the + button, choose Last opened date, then is not in the last, and enter 6 months.
- Click Save, name it something like Stale downloads, and add it to the sidebar.
Last opened date, not date added, is the criterion that matters. A file you downloaded two years ago and open every month is in use. A file that arrived last week and has never been opened is not.
Now you have a folder that fills itself with candidates, and clearing it is a two-minute job whenever you notice it is long.
The things in there that are not disposable
A few kinds of file end up in Downloads and are not replaceable, so scan for them before you select all:
- AirDrop arrivals. Anything sent to your Mac by AirDrop lands in Downloads, including files from a phone that may not exist anywhere else.
- Mail attachments you saved. Saving from Mail defaults to Downloads for a lot of people, and the original message may since have been deleted.
- Exports from apps. Several apps propose Downloads as the default export location, so a rendered video or a generated report can be sitting in there as the only copy.
The Date Last Opened column separates these from the rest quickly. Anything you have opened more than once is worth a second look before it goes.
Stop it filling up again
Tidying once is a chore. Tidying repeatedly is a system failure.
Set the Trash to empty itself. Finder, Settings, Advanced, then Remove items from the Trash after 30 days. Deleting things from Downloads does nothing for free space until the Trash is actually empty, and this removes the step you forget.
Trim the browser’s download list. In Safari, Settings, General has a Remove download list items option; set it to after one day so the list stops being an archive. The same panel sets the download location, and turning off Open safe files after downloading is worth doing regardless, because it stops archives silently expanding themselves next to the original.
Decide what Downloads is for. The version that works is treating it as an arrivals hall: things land there, and anything you intend to keep gets moved somewhere named within a day or two. Anything still sitting there after that is by definition disposable.
When the folder is past sorting by hand
If Downloads has thousands of items across several years, sorting it by hand stops being reasonable and you start deleting carelessly, which is how the one file that mattered goes.
Crumb has an Organize tool for exactly this shape of problem: point it at a messy folder and it sorts the contents by type, so you get images, archives, installers and documents separated before you decide anything. Its Duplicates tool covers the repeated-download problem in the same pass. It also audits the rest of the Mac read-only, which is useful if Downloads turns out not to be where your space actually went. Be clear about what it is not: it does not recover anything you have already deleted, and nothing is removed until you approve the plan.
For most people, though, the Finder steps above are the whole job. macOS genuinely does have the tools for this one.
Questions
Why has my free space not changed after deleting things? Deleted files sit in the Trash until it is emptied, and even then the space can be reported as purgeable for a while, particularly if Time Machine has taken a local snapshot that still references the files. Purgeable space explains why the number lags and when it catches up.
Will deleting a .dmg break the app I installed from it? No. Installing copies the app to your Applications folder and the disk image is not consulted again. The only reason to keep one is if you want to reinstall without downloading, which for most apps is not worth the gigabyte.
Can I move the Downloads folder to an external drive?
You can change where a browser saves files, which is the practical version and it works well. Moving the ~/Downloads folder itself is possible but macOS and various apps expect it at that path, so you inherit odd behavior for very little gain.
Is it safe to just select all and delete? Only if you have looked at the Date Last Opened column first. The risk in Downloads is never the installers, it is the AirDrop arrival or the export that has no second copy.
