Can I select a local drive letter for scanning or must I select the directories?

Yes, youcan scan complete hard disks like "C:\".

Whe using NTFS change journals, do I need to run an initlal scan then active the change journal option? What is the performance impact to a server with the NTFS Change Journal option acivated. Is the recommended setting to use NTFS change journals when possible or use scheduled scans? Which scan would normally take longer, the initial scan or a subsequent scan?

Yes, you always need an initialscan, even when using NTFS Change Journals.It 's hard to say how muchthe performance impact will be. This depends on the changes done on the observedserver. The most performance will be hold by the database server.It is only recommended touse the NTFS Change Journals, when you need always up to date size information.Normally the update scan isfaster than the initial scan, but this also depends on the number of changes onthe observed file system share.

Is it possible to obtain a hard copy of the user manual for this application ?

When I use File Search in SpaceObServer, is it searching the database or the network? In other words, will it show me what 's on the network now, or what was on the network at the time of the last scan?

The SpaceObServer File Search take its values form the stored information inside the database. This way it is posible to apply many kinds of file "filters" on demand, without any needed rescan.

During the analysis of a Novell Share / Unix-Samba Share, the owner of files weren’t recognized. The Novell Share shows "all" and the Samba Share shows "unknown". How does SpaceObServer collects these information?

Unfortunately,the Netware Client for Windows provides no information about compression rateor file ownership to the regular Windows API. Some Samba versions do the samein Unix environments. So developers for Netware or Samba have to add a specialsupport functionality. We will provide this functionality in a later version ofSpaceObServer. Allthe other functions are available on Netware drives.

Is it possible to schedule scans for a certain day of the week? The Scan setting dialog shows only a "Scan every X days" option.

This option will beavailable with SpaceObServer V3.0 or later.

What can I do to enhance the scan performance of SpaceObserver ? We use MSDE2000 as a database server and during the scan the sqlserver.exe consumes habitually more than 50% of CPU cycles (PIV-3GHz) as well as more than 1 GB RAM. I did reference tests with TreeSize, and it scanned the same directories up to 20 to 30 times faster.

There are several possibilitiesto enhance the scan performance StoringScan results performs best, if you use a SQL server database, esp. an MS SQLserver database. MS Access should always be second choice when you are in forfastest performance.Localscans are way faster than scans over a network. We advise to installSpaceObServer on every client and to scan locally. You can remote controlSpaceObServer and do your data mining with theSpaceObServer-Client-Application.Thebottle neck of the whole system is the SQL server, so we recommend to use apowerful computer as server computer. 2-3 GB RAM and a fast processor ismandatory for a heavy loaded database server. Althoughit is possible to tweak the database performance by adjusting certain indicesand stats, we can not recommend it, because the database is optimized forsupporting all functions of SpaceObserver. Tweaking the database would(possibly) result in faster scans, but at the costs of a decreased efficiencyin recalling and administration.  Comparedto TreeSize, SpaceObServer scans seem to be inferior in terms of scan speed.But SpaceObServer can access archived file system information much faster andoffers a wider range of filtering options for a more detailed file search. Allover that, you can do all this remotely from another computer. Themain question is : What program suits your needs most? A small help in findingan answer could be this summarising table

Can SpaceObServer auto-generate scheduled reports? E.g. produce a report once a day?

That’s possible withSpaceObServer version 3 and later. There are a number of settings as well asthe possibility for automated scanning and reporting controlled by scripts. Forfurther information, please refer to the SpaceObServer manual.

Is it possible to export a result list after a scan for all files of a specific user including their full paths to Excel? Many users have more than 100 files, so the Top 100 listing is of very little help, and the Details view seems not to provide an Excel export button. What can I do?

The Details view doesindeed provide a possibility to export to Excel. You will find it in thecontext menu after right-clicking on the result list and choosing SpaceObServer / Export to Excel.

During the installation of the MSDE2000 engine, the install program tries to download the engine from the internet over and over again although the MSDE engine runs already. A direct selection of the SQL server doesn’t help, as the installer still tries to download the system from the internet.

If the MSDE is installedand running, you just have to set up the MSDE as database connection forSpaceObServer by selecting "MS SQL Server" under Views / Options / Database.

How can I choose, which column should appear in a report or in an exported file?

You may selecta column under View / Options / Columns after you chose an export medium fromthe topmost drop-down box of the form.

Whenever I try to scan DFS shares, no files were found. How can I scan DFS shares?

DFS share does notrepresent a physical directory structure, so the options "Follow Mount Points and Symbolic Links" (Configure Scans / ScanOptions) must be set. DFS shares will be included in your scan reportautomatically then.
