I have a ~/Library/Developer
used by Xcode.app in El Capitan. The Finder
> Get Info
reports a size of 24 gigs. But the two nested folders each report only 6 gigs each. So ( 2 * 6 ) = 12, and ( 24 – 12 ) = 12. Where is the other 12 mysterious gigs?
I am showing invisible files/folders. So I believe I have not overlooked any other content. I did recently delete much content from there, and emptied the Trash.
How can I track down this huge discrepancy?
Using the du
, the “display disk usage statistics” tool, where -d
is depth (Display an entry for all files and directories depth directories deep) and -h
is "Human-readable" output (Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte).
Outer folder:
cd ~/Library; du -d 1 -h;
…
11G ./Developer
…
Inner folders:
cd ~/Library/Developer; du -d 1 -h;
706M ./CoreSimulator
4.4G ./Shared
5.9G ./Xcode
11G .
cd ~/Library; du -d 1 -h;
But the Get Info
reports twice that, 24.x gigs.

tl;dr
du
tool to see the truth.Details
While shooting a screenshot of the Finder > Get Info showing 24 gigs and the results of the
du
command-line tool showing only 11 gigs, the Get Info panel changed with an automatic update. This was after a reboot and after 1-2 hours of repeatedly showing 24 gigs.So the Finder must be caching information about the folders long after deleting gigs of data in a large numbers of files.
As suggested by tubedogg, use the
du
command-line tool to see accurate readings of your folder sizes.
