Downloads is the cheapest few gigabytes on the machine

Installers you already ran, files you opened once, and a Storage Sense rule that deletes by age without asking what anything is.

5 min read

Downloads is the one folder where almost everything has already done its job. The installer ran, the attachment was read, the ISO was written to a stick two years ago. Nothing removes any of it, because Windows cannot tell which of those is true.

Largest first, then oldest

# The twenty largest, with age
Get-ChildItem "$env:USERPROFILE\Downloads" -Recurse -File -Force -EA SilentlyContinue |
  Sort-Object Length -Descending | Select-Object -First 20 `
    @{n='MB';e={[math]::Round($_.Length/1MB)}}, LastWriteTime, Name

# Everything over 100 MB that has not been touched in a year
Get-ChildItem "$env:USERPROFILE\Downloads" -Recurse -File -Force -EA SilentlyContinue |
  Where-Object { $_.Length -gt 100MB -and $_.LastAccessTime -lt (Get-Date).AddDays(-365) } |
  Sort-Object Length -Descending |
  Select-Object @{n='MB';e={[math]::Round($_.Length/1MB)}}, LastAccessTime, FullName

The second command is the one that finds real space: large, old and never opened again. Installers, disk images and video exports dominate it on most machines.

What is safe to remove without thinking

FileKeepWhy
*.exe and *.msi installersNoThe application is installed, and a new version exists anyway
*.iso imagesOnly if you still need to write oneSeveral gigabytes each, usually redownloadable
*.zip you have already extractedNoThe extracted folder is beside it, so you are keeping two copies
Bank statements and documentsYes, and file them elsewhereThis is the folder people lose these in
.crdownload, .part, .tmpNoAbandoned transfers, holding their full size

Storage Sense can do it on a schedule

Settings, System, Storage, Storage Sense has a rule for Downloads: delete files that have not been opened for 1, 14, 30 or 60 days. It is off by default and it is the only Storage Sense rule that touches files you chose to keep.

Moving the folder to another drive

  1. Create the destination first, for example D:\Downloads.
  2. Right click Downloads in Explorer, Properties, Location, Move.
  3. Choose the new folder and accept moving the existing files.
  4. Browsers follow the change, because they ask Windows where Downloads is.

On a machine with a small system drive this is one of the highest value moves available, and unlike moving an installed program it is supported, reversible and takes a minute. The general case is covered in C drive against D drive.

Files deleted in Explorer go to the Recycle Bin, so nothing is gone until that is emptied. On a full drive that is the step that actually returns the space, and each drive keeps its own bin: the Recycle Bin, per drive.

Common questions

Is it safe to delete everything in Downloads?

Almost everything there has already served its purpose, but it is also where people lose statements and documents they meant to file. Sort by size, check the large items, and delete installers and disk images without hesitation.

How do I find the largest files in Downloads?

Sort by Size in Explorer's Details view, or run a PowerShell listing sorted by Length. Filtering to files over 100 MB that have not been opened in a year finds the ones worth removing.

Should I let Storage Sense clean my Downloads?

Only if you treat Downloads as temporary. It deletes by age regardless of what a file is, and it is the one Storage Sense rule that touches files you chose to save rather than caches.

Can I move the Downloads folder to another drive?

Yes. Right click it, Properties, Location, Move. Browsers and applications ask Windows where the folder is, so they follow automatically.
