That distinction makes sense—showing the space freed separately from the on-disk size seems especially useful on APFS. The snapshot warning sounds helpful too; it should prevent a confusing surprise.

Today I learned the newer hard drive format, APFS, is known to be slow at scanning folders on spinning hard drives.
The Mac OS Extended (Journaled) format usually scans noticeably faster than APFS for spinning drives.
Apparently, APFS is better for solid-state drives.

I think most computers are gonna work that way unfortunately but if you open up disk utility and go to View > Show APFS Snapshots and then start deleting old ones you should free up some local disk space. not sure if it'd be enough though, that's like a third of your disk

I went back to Disk Utility to reformat the drive back to Journaled. It’s no longer an option! The only format options are now APFS. Grrrr.

Oh yeah D3D leaks a _lot_.
If you have a CrossOver license you can get the preview here: www.codeweavers.com/preview/down...
You just have to duplicate the bottle first, but that should be a "free" operation if your disk uses APFS (if CodeWeavers used a clone operation like they should, anyhow)

I Paid 74 GiB for Identical Bytes, 12.5 GiB Left on My Disk
My disk has 12.5 GiB free; 74 GiB had already gone on identical bytes. What an APFS clone really costs, and the detector that was missing.

Yes! Since 1.5.1 TreeX shows two numbers: what deleting really frees and what it takes on disk. Folders that are usually clones get an "on APFS it may free much less" note, and it warns when Time Machine snapshots will hold the space for a while.

Simulators are the tricky row to size. Clones left in XCTestDevices by parallel test runs share blocks with the original via APFS clonefile, so a folder walk counts them in full. I had 26 that du put at 76G; deleting them freed about 1G by df.

Xcode leftovers is where per-folder sizes mislead most. Parallel test runs leave simulator clones in XCTestDevices that share blocks with the original via APFS clonefile. I had 26 that du put at 76G; deleting them freed about 1G by df.

The APFS clone detection in the README is a useful detail. Two files can share storage, so deleting one may free much less than its apparent size.

One trap when you test it: APFS frees blocks asynchronously, so df can lag 20 seconds or so behind the delete. And measure one group at a time. My first reading said 20G freed, but 19G of that was an npm cache clean I ran in the same pass.

3/ The build cache is the most interesting part probably. It shares 𝘁𝗮𝗿𝗴𝗲𝘁/ and 𝗻𝗼𝗱𝗲_𝗺𝗼𝗱𝘂𝗹𝗲𝘀/ between worktrees with 𝗰𝗼𝗽𝘆-𝗼𝗻-𝘄𝗿𝗶𝘁𝗲, so a new worktree does not rebuild and does not copy gigabytes. That needs APFS, btrfs or XFS.
