Something eating HD space?

Try running Spacemonger on it.

Old SpaceMonger v1.x

Jam it back in, in the dark.

Since it's showing on C:\Windows, we can eliminate the following possibilities:

1. Large MFT file allocation (on the root)
2. System Restore checkpoints (on C:\System Volume Information)

If Spacemonger doesn't show you where the phantom files are, try the following:

1. Do a full CHKDSK and see if there are any orphaned files
2. Take ownership of C:\Windows\, and unset read-only and hidden attributes. Apply to all files and subdirectories. (You can try to unset the system attribute, though it's only possible with DOS

There's nowhere I can't reach.

It's strange. I can see my \Installer folder just fine, and it adds up to about 1.5 GB in size.

> Whether safe to delete

Yes, you MAY delete the whole folder if you wish. However, you will lose the capability to uninstall / upgrade any programs. You will have to do it the old-fashioned way by hunting down errant program files and registry entries.

> Solution

Install the Windows Installer Cleanup Utility. After installation, you will find a program called msizap.exe on C:\Program Files\Windows Installer Clean Up\. Use it to remove any orphaned patch files from your system by running msizap g!.

Do let us know if this works for you - I'm interested in the outcome.

> Reinstall MS Office

It won't hurt.

This thing is sticky, and I don't like it. I don't appreciate it.
