Anyone use Glary Utilities? It’s a powerful free program for PC maintenance. One of it’s features is to show you folder sizes. So, at the top level you may see your C: drive and all the immediate sub-folders with their sizes. You can then drill down to see further sub-folder sizes. Very useful. My issue is that Glary shows my C: drive as 80GB used space, but Windows (Vista 64-bit) shows 120GB used. Now, Windows is just a total number, while Glary shows me exactly where the usage comes from. But 40GB is a sizable variance. I’m curious if anyone else has a similar difference or knows why it comes out this way.
I use it on occasions to clean up the registry and adjust start up programs.
I have no idea what your problem is. Perhaps you have mapped a partition to the C: drive as a sub directory and Windows adds that to the total and Glary doesn’t. I’ve noticed programs often handle this situation differently. Like I said I can’t tell you why the problem.
Odds are that Glary is only counting folders to which it / you have access rights.
It’s got electrolytes, they’re what plants crave.
I’m not familiar with GU, and I don’t think the following is a significant part of the discrepancy you’re reporting, but:
Hard drive space is usually divided in blocks, with some blocks used for data and others for metadata. Metadata blocks store things like file names/paths & permissions, while data blocks store the actual contents of the files. This means that a file containing only a single byte will take at least that byte plus the metadata (and you can probably assume that each file will take the same amount of metadata).
Also, blocks are of a fixed size (which can be set while formatting a drive/partition, but can’t be easily changed afterwards) and data blocks are not shared between files. Typical block size is a multiple of half a kilobyte (with 0.5 or 1 Kb as common defaults). That means that the “1 byte” file will use up a disk space of at least 1 block + some metadata.
Taken together, this means that if you subtract the total content size of all files on your drive from the total data size of your partition, you’ll end up with a higher number than the actually usable free disk space.
