The software is available as Standard and Enterprise Edition
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
A flexible file search, with predefined searches for very big, old or obsolete files allows filtering and listing files directly from the database. A duplicate file search is also included.
Operate via Remote
The SpaceObServer Remote Client (sold separately) is a management tool to configure scans, view scan results and generate exports remotely from additional machines in your network.

  • 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.

    • 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.
    • space usage history shows development over time and provides an approximated forecast for the future.
    • View, print and export 3D bar, pie, line charts and tree maps.
    • Scanned directories can be merged in "containers", allowing analyses across drives, e.g. search for duplicate files.
    • Statistics can be grouped by users or file extensions.
  • Remote access
    • The SpaceObServer Remote Client (sold separately) offers access to all scan results from different workstations in your network.
  • 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 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.
