The Windows Explorer shows the space that is physically allocated on the drive while SpaceObServer shows the space that is occupied by all files under a certain path. Please make sure that you have the view option "Allocated Space" activated when you are interested in the physically allocated space. Beyond the space that is needed for storing the files itself, additional space is used for storing management data like the File Allocation Table of the file system or the boot sector. This is usually 0.5 - 2% of the occupied space. It is not possible to free this space with SpaceObServer or any other tool. Another possibility is that you are using a Software RAID - like Windows offers it - which spreads the data with redundancy over several disks. These disks will appear as one logical volume and the failure of a single disk will not cause any data loss. But for storing the redundant information additional space is needed.
On Thinkpad laptops the Rescue&Recovery feature may use a lot of disk space in the folder "RRBackup" which is not accessible to other applications.
If a drive letter points to a sub folder of a network drive, the allocated space (correctly) reported by SpaceObServer may also be much smaller than the physically allocated space on this drive reported by the Windows Explorer because it is possible the whole drive is not accessible through the network. A further possibility is that not all parts of the drive could be scanned due to access restrictions. Turning on the Option "Track NTFS Alternate Data Streams and NTFS Hardlinks" in the "Configure Scans" dialog may result to more accurate results but slightly slows down scans.

Please execute the following steps:
1. Open the Windows system dialog "Services" ("Control Panel > (Performance and Maintenance) > Administrative Tools > Services").
2. In the list of the services (local) look for "SpaceobServer Agent" and stop this service.
3. Select "Properties" in the context menu of "SpaceobServer Agent".
4. Switch to the tab "Log On" and change from the "Local System account" to "This account".
5. Insert the necessary login information (username, password) for a user account with sufficient network access rights.
6. Start the service "SpaceobServer Agent" again.
Note: If you use a MS SQL Server and the integrated Windows security, the user you used for the service login have to have read and write access to the database!

Starting the setup with the command line parameters /SILENT /SUPPRESSMSGBOXES /PASSWORD=<installationkey> will perform a silent and automatic installation with the default settings. Please replace <installationkey> with the license key that you received after your registration. Using /VERYSILENT instead of /SILENT will prevent any visual feedback.
Use the options /SERVICEUSER <domain>\<username> and /SERVICEPWD <password> within the initial installation of SpaceObServer to specify the login information of the SpaceObServer scan service. Otherwise the local system account is used here, which can lead to problems when scanning network shares (See: "SpaceObServer doesn't start to scan a selected directory...").
The option /DIR=<directory> can be used to override the default install path.
After this you may configure your database connection using the OLE Automation Interface of SpaceObServer. A template script for an Unattended Installation of SpaceObServer can be found in the installation directory, in the sub directory "Demos" (See "UnattendedInstallation.vbs").

Updates are free within your maintenance period (12 to 60 months after purchase). You are allowed to use the software as long as you want to. If your maintenance period expires, you will get no more free updates, but you will be able to purchase a maintenance renewal for a reduced price in our customer's area.

In the "Help" menu of SpaceObServer you can use "Check for update" to check online if there are updates available. Within your maintenance you can download the latest version directly from the shown dialog. Alternatively you can download the new installer from our customer's area.

To update to the latest version just run the new installation file. Your scan data and all your user settings will persist.

The free trial version allows you to evaluate the software before you buy it. Further usage of the software after that period is not permitted and violates the law. In order to allow our customers to fully test our software products, our trial versions usually do not contain significant limitations. But the software may remember you from time to time that you should purchase the software after your testing is finished.

The Enterprise edition offers all the features of SpaceObServer while the Standard edition is limited in some points.

With the Standard edition you can scan only one server, Exchange Server scans are not available and the OLE Automation interface is not included.

Please find a detailed comparison of both editions here.

For questions regarding prices and purchasing, please refer to our price list and our ordering FAQ.

SpaceObServer is compatible with all Windows versions currently supported by Microsoft, including supported Windows Server versions (latest patches and updates should be installed). Please find more details here. SpaceObServer can be used in a virtual environment.

Unfortunately there is no short and easy answer to this question because usually one cannot know where a file came from and what it is used for. Generally temporary files and cache files of the internet browsers can nearly always be deleted safely. Besides deleting files, the File Search of the software offers you to move files to a different drive or to a compressed ZIP file (preserving the file system hierarchy) which can then be archived. That way files that are still needed can be easily restored, either manually or by using the restore script that the software is able to generate optionally.
