SpaceObServer is a powerful and flexible hard disk space manager for Windows which stores file system information in a database and thus will help you free up valuable disk or server space.

The software is available as Standard and Enterprise Edition. The Comparison Table lists the feature differences of the editions.


Why SpaceObServer:

·         Regular and automatable storage scans

·         Recognize increased disk space on folder level

·         Identify unnecessary files

·         Automated reporting via OLE Automation

·         Cross-platform SSH and Exchange mailboxes scans

Analyze Drives and Directories

SpaceObServer scans local and network drives as well as Exchange mailboxes using a background service and stores their structure, sizes and properties in an SQL database. Linux and Unix file systems can be scanned via SSH (Secure Shell). In an Explorer-like user interface the collected data can be viewed and browsed in hierarchical or tabular views, 3D bar, pie, line charts and tree maps. Using the archived data you are able to track the development of the space usage from past to present, and forecast future size usage.

Find Redundant Files and Similar Folders

A flexible file search, with predefined searches for very big, old or obsolete files allows filtering and listing files directly from the database. Find duplicate files and similar folder structures with the search feature.

Operate via Remote

The SpaceObServer Add-ons SpaceObServer Remote Client and SpaceObServer Web Access (sold separately) you can access scan results from other machines or via your internet browser. 


SpaceObServer 6.0

New benefits

• a unique similarity search
• scan of access rights (ACLs)
• new reporting- and filter-functions 
    (e.g. OUs for Exchange scans)
• more performance


  • Track Disk Space Usage Continuously in the Background
    • The SpaceObServer Agent scans selected drives and stores the collected data in an SQL database.
    • Scan network drives without the need to install additional software on the server.
    • Scan all shares of a complete server at the touch of a button or schedule scans.
    • SpaceObServer can access the NTFS Change Journals of local drives and updates information about local NTFS drives continuously.

      The Enterprise Edition offers even more disk space management features:
    • Determine disk space occupied by Exchange mailboxes (right down to folder level).
    • Linux and Unix file systems can usually be scanned via NFS (Network File System) or Samba - the Enterprise Edition allows you to scan them directly via SSH (Secure Shell).
  • Analyze Disk Space
    • The size of each folder is displayed directly in the file system tree: easily discover which folders occupy most of your hard disk space.
    • Visualize disk space usage and track down unwanted files with several visualization options.
    • A space usage history shows development over time and provides an approximate estimate of disk space usage development for the future.
    • View, print and export 3D bar, pie, line charts and tree maps.
    • In a file preview you can see detailed information about selected files.
    • Scanned directories can be merged in "Containers", allowing analyses across drives, e.g. to search for duplicate files.
    • Statistics can be grouped by users or file extensions.
    • Compare folders and file structures to find similar or identical trees.
  • Remote access with Add-ons (sold separately)
    • The SpaceObServer Remote Client offers access to all scan results from different workstations in your network.
    • Use the SpaceObServer Web Access to access scan results in your standard web browser.
  • Search for Files
    • The highly customizable file search allows filtering your files by size, last change, last access and creation date, extension, filename and path pattern, file attributes, owner, NTFS permissions or full path length.
    • Filter options are applied directly to the directory tree and all other views.
    • Duplicate files can be identified by the MD5 checksum of their content or a combination of name, size and last change date, for even easier deduplication operations.
  • Clean up Disk Space
    • Checked directories and files can be easily moved, zipped or deleted. You can choose to keep file permissions and create stub files for moved files.
    • State of the art deduplication-feature: SpaceObServer can replace duplicate files with NTFS hardlinks.
  • Export Results
    • Print reports showing the directory structure or save them as Excel, XML, PDF, HTML, CSV or text-file and export them to the clipboard.
    • Directly send reports via e-mail.
    • Charts can be exported in the common graphic formats JPG, GIF and PNG.
  • The SpaceObServer Enterprise Edition offers automated Reporting via OLE Automation
    • The OLE Automation interface allows scheduling your exports from within your own scripts or applications.
    • All programming languages that offer an OLE Automation interface are supported (e.g. C#, VBScript, VB.NET, Delphi, Windows PowerShell, VBA in Microsoft Office).
    • Programming examples are included.
  • Complete NTFS support
    • SpaceObServer supports Unicode file and folder names.
    • File-based NTFS compression.
    • Alternate Data Streams (ADS) and hardlinks are shown.
    • SpaceObServer finds and processes file paths exceeding 255 characters.
    • SpaceObServer analyzes NTFS permissions and can filter for files with specific access permissions.
  • Customized View
    • Visibility and order of the columns can be configured for the details view and each export type separately.
    • You can easily customize the output format, e.g. number of decimals, size unit (Byte, KB, MB, GB, TB or automatic display of an appropriate size unit) etc.
  • SpaceObServer supports:
    • Unicode file and directory names.
    • The Explorer context menu within the SpaceObServer interface.
    • Windows File Paths longer than 255 characters.
