Whatever filled your disk,
start here.

The warning appears, but nothing obvious has changed. The space is spread across thousands of folders, and none of the usual suspects explains it.

1. Scan the whole drive, or just your home folder.
2. Follow the biggest arcs and rectangles down to the folders taking more than their share.
3. Move, zip or send what you don’t need to the Trash or Recycle Bin, straight from the results.

Package caches, node_modules folders, Xcode data, Docker build cache and downloaded models pile up, project after project. You know they’re there, but not which ones you still need.

1. Run Deep Cleanup to find developer caches, project build output and AI model stores.
2. Expand any item to read what it holds and what you keep.
3. Choose what to clear and confirm. AI models are removed only when you pick them yourself.

Old videos, disk images, archives and installers sit in folders you rarely open, quietly taking up room long after you needed them.

1. Run Large File Cleanup on a drive or folder, and set the minimum size.
2. Filter by video, archives, AI models or another type, and check each file’s path and date.
3. Select the files you no longer need and confirm.

The same photos imported twice, an export saved in three places, a file you downloaded again. The names don’t match, so you can’t spot the copies by eye.

1. Run Duplicate Cleanup to group files with identical content, whatever their names.
2. Let smart select keep one copy in each group, by path, name or date.
3. Delete the extra copies, move them to an archive, or replace them with links.

Deleting an app rarely removes everything. Caches, preferences and support files stay behind long after the app has gone.

1. Find the app in App Uninstaller. It shows whether the app must be closed or needs administrator approval.
2. On Mac, review each related file, labelled required, can be recreated or may contain user data. On Windows, DiskHalo runs the app’s own uninstaller.
3. On Mac, Deep Cleanup also finds leftovers from apps you removed before.

Shared storage fills up too, but downloading a whole bucket or document library just to see what’s inside isn’t realistic.

1. Open Remote sources and choose the provider: Amazon S3, Azure Blob Storage, Google Drive, SharePoint, Outlook, WebDAV or SFTP.
2. Add up to eight locations and a saved credential. Credentials stay in your system’s credential vault.
3. Explore the results in the same views you use for a local drive. DiskHalo reads names, sizes and dates, never file contents.

Helpers, updaters and background agents arrive with every app you install, and some stay behind after the app has gone.

1. Open Startup Items to see what starts with your computer and when you sign in.
2. Expand an item to see what it runs and whether it needs attention.
3. Switch off what you don’t need, and remove entries whose app is gone.

You want to see how a drive or project folder is growing, without remembering to check it every week.

1. Create an Automation job with the locations to scan, a comparison snapshot and an export.
2. Email the report through your own mail server, or save it as XLSX, PDF or CSV.
3. Schedule it to run weekly. Every run keeps an audit trail.
