Use SpaceSniffer

SpaceSniffer is easy to use. Once you get the files using the link above, extract the contents of the zip file anywhere and run it SpaceSniffer.exe. You can also run the EXE file directly from the ZIP file. However, this is not recommended because the program runs with limited permissions.

When you start SpaceSniffer you will see a Choose your room Screen displayed. It lists all of your available drives, as well as the ability to select a specific folder to scan individually. Once you select a drive, the program goes to work.

This is SpaceSniffer's main screen, and it appears almost immediately. Unlike other data visualization programs, SpaceSniffer always scans.

As mentioned above, this is the program that will sort your data into easy-to-read blocks. The blocks are larger or smaller depending on how much size they take up on your drive. You will be able to spot the largest files instantly. In my case, I seem to have a very large Hyberfil.sys file.

The first thing you may notice is an infrequent blink across the blocks. Depending on where you are scanning, SpaceSniffer may already be detecting activity on your system.

In this example mine app data Folder was blinking a lighter color, indicating that Windows is using the data. This can mean that data is being created or deleted.

Since this is my AppData folder, it is most likely blinking due to temporary files that Windows is storing in my cache. If you've scanned your entire drive, you might see the same blink in the same place.

This is a great way to ensure that SpaceSniffer is verifying your information correctly.

If you click once on one of the blocks, the display of the folder name changes to the folders within. If you double-click on one of the blocks, the program will shift focus and enlarge the specified folder to take up the entire screen. You can also right-click anywhere to open the standard Windows context menu, where you can delete or rename files.

Learn the Toolbar from SpaceSniff

It can be easy to get lost in this program so it is well worth learning the toolbar. The toolbar contains many of the program's most useful functions. Below you will find the most important navigation and scanning functions that you need to use SpaceSniffer efficiently.

  • This is shown as a white box New view Button. Pressing this button will bring up the Choose your storage space screen and allow you to scan an additional drive or partition.

  • The green arrows are Go forward and Go back. These help with navigation.

  • The button with a folder and an arrow next to it is the Go to the upper level Function. This is a helpful navigation tool as it instantly brings the screen to a folder higher up in the directory. So, if you accidentally clicked a few levels too deep, this can be used to find your way back.

  • Next to it is a home icon, and that is To home page. It will take you back to the root directory of your drive.

  • Press the two blue arrows Performs a new master scan. This will cause SpaceSniffer to start the scan over.

  • The white file icon with gray arrows is Perform a new scan of the enlarged view. This will cause SpaceSniffer to start the scan from scratch in the window you are currently viewing.

The green star symbol is Show free space. This will create an additional block that shows how much free space you have on your drive.

After all, is the ghost symbol Show inaccessible area, and the flower is that donation Button. Showing inaccessible space is a feature that may not do anything for you once SpaceSniffer has successfully scanned your system. However, this feature can highlight where SpaceSniffer may not have permission to scan.

Error cannot be investigated

Let's say SpaceSniffer shows inaccessible space or shows an error log when you start scanning. In this case, there is a good chance that SpaceSniffer does not have sufficient permissions to scan your entire drive.

This is not a big problem. SpaceSniffer can do its job without full access to your drive; It just won't be able to provide all of the details about restricted folders. When this problem occurs, you can try running SpaceSniffer as an administrator.
