An interesting discussion of Windows disk space usage in the upcoming Windows 7 release:
FolderSizes v4.7 is now available for download.
As I discussed in a recent blog entry, this new release provides a fascinating new way to view hierarchical folder structures – the folder map. We’re extremely excited about this capability, as we believe this is a best-in-class implementation of a very modern data visualization technique known as treemapping.
Version 4.7 of FolderSizes also introduces a new license type – the personal edition license – designed specifically for home users (and priced accordingly at only $25.00 USD). There are a few functional limitations (described in detail here) in the personal edition of FolderSizes, and it cannot be used in any business or organizational environment. But for folks needing a disk space analysis tool for home / personal use, this new license type should be very welcome. In fact, users have been asking us for this for quite some time.
Additional information about v4.7 can found in the online release notes.
Let’s talk about what we’ve been working on for our upcoming FolderSizes v4.6 release.
First and foremost, v4.6 contains a new integrated scheduling facility. With this tool, you can schedule the execution of any FolderSizes report type and export those results in a variety of formats. Here in our development labs, we’ve scheduled the generation of all of FolderSizes’ various report types, exporting each of them (in HTML format) to a shared folder on our network (effectively building an archive of data storage reports that speed and simplify storage hotspot identification, as well as providing historical context).
The next major focus of FolderSizes v4.6 is performance. Nearly every feature has received a comprehensive performance and resource usage evaluation, and this has process resulted in:
- The introduction of a new file owner data lookup cache
- Numerous improvements to our folder analysis data caching technology
- A nearly 60% memory usage reduction in many file report scan scenarios
- Numerous performance boosts when scanning remote (network) paths
- New options that provide more granular control over scan-time performance
Some of these improvements might sound a bit technical and geeky – but believe me, they amount to a serious performance and resource usage improvement in v4.6.
There are tons of other improvements as well – improved visual theme switching, “filename only” duplicate file matching, a greatly improved duplicate file report HTML export format, a new “allocated” column in several of the file reporting detail views, and much more. We also threw in a handful of bug fixes for good measure.
FolderSizes v4.6 is a free upgrade for existing v4 license holders. Get yours now – fresh off the compiler.
FolderSizes is featured in the Toolbox : New Products for IT Pros section of Microsoft TechNet magazine (May, 2008 edition).
It’s a really nice review, although I’m not quite sure how Greg (the reviewer) managed to capture such an ugly screen shot of the main window. To each their own, I suppose.
With MS Vista Service Pack 1 now available, some users have observed a non-trivial hit to their available disk space after installing the update.
What’s happening is that SP1 backs up previous versions of many components during installation, consuming quite a bit of disk space in the process. If you’re completely confident that you won’t need to uninstall SP1, you can actually reclaim that space. Vista SP1 includes an optional tool called Vsp1cln.exe which will remove the files backed up during installation. After the Vista SP1 installation completes, Vsp1cln.exe will be located in your Windows\system32 directory. You can run it by dropping to a command prompt (or press “Winkey + R” on your keyboard) and and typing Vsp1cln.exe and pressing Enter.
The cleanup utility will warn you that you’re about to make your Vista SP1 installation permanent, and prompt you for confirmation. Once confirmed, the cleanup process will begin. Again, don’t execute this file removal utility unless you’re certain that you won’t need to uninstall Vista SP1. But if you’ve created a full backup of your computer prior to installing Vista SP1 (I actually prefer to image my entire system before doing this sort of thing), this may not be much of a concern.
So how much disk space can you reclaim by running Vsp1cln.exe? Most users are reporting just under a gigabyte of recovered space, depending upon which version of Vista is installed. Your mileage may vary. And if you still need a better understanding of how your disk space is being consumed, well then you need FolderSizes.
