SpaceObServer is a powerful and flexible hard disk space manager for Windows.

The database-based software is available as Standard and Enterprise Edition. The comparison table lists the feature differences of the editions.

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 filesystems 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. 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. The SpaceObServer Remote Client is a management tool to configure scans, view scan results and generate exports remotely from additional machines in your network.

Main Features
* Scan Continuously
o A background service, the SpaceObServer Agent, regularly scans selected drives and stores the collected data in an SQL database.
o Scan network drives without the need to install additional software on the servers you want to observe.
o Determine disk space occupied by Exchange mailboxes (down to folder level)*
o By using the NTFS Change Journals SpaceObServer is able to update information about local NTFS drives continuously, which results in disk usage information that is always up to date.
o Linux and Unix file systems can be scanned directly via SSH (Secure Shell)* or NFS (Network File System)

* Analyze Disk Space
o The size of each folder is displayed directly in the file system tree. This way you can easily discover which folders occupy most of your hard disk space.
o A space usage history shows development over time and provides an approximated forecast for the future
o View, print and export 3D bar, pie, line charts and tree maps
o Scanned directories can be merged in "containers" - allows analyses across drives, e.g. search for duplicate files
o A list displays the size for each folder grouped by users or file extensions

* Search for Files
o 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.
o Filter options are applied directly to the directory tree and all other views.
o Duplicate files can be identified by the MD5 checksum of their content or a combination of name, size and last change date.

* Clean up Disk Space
o Marked directories and files can be easily moved, zipped or deleted. You can choose to keep file permissions and create stub files for moved files.
o Modern deduplication: Support for the file based NTFS compression, hard links and alternate data streams (ADS)

* Export Results
o Printed report (showing the directory structure), Excel, XML, PDF, HTML, text file or clipboard
o Charts can be exported in common graphic formats (JPG, GIF or PNG)

* Automated Reporting via OLE Automation*
o The OLE Automation interface allows scheduling your exports from within your own scripts or applications*
o All programming languages that offer an OLE Automation interface are supported (e.g. C#, VBScript, VB.NET, Delphi, Windows PowerShell, VBA in Microsoft Office)
o Programming examples are included

* Customized View
o Visibility and order of the columns can be configured for the details view and each export type separately
o 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.

* Support for:
o Unicode file and directory names
o Explorer context menu is supported within SpaceObServer
o File paths > 255 characters
