There are 3 possible reasons why "TRIAL VERSION" still shows up:
1. You did not download and install the full version from the URL you received after the purchase.
2. You have accidentally installed the trial version again. (Have you been asked for an installation key?)
3. You have installed the full version to a different folder than the trial version, which is now still on your disk.
To see the total size of all duplicate files, mark all entries in the 'Duplicate Files ' list (Ctrl-A). The total size of all the files is then shown in the status bar.
Note: This is the size of all the files shown in this list, so there are also the original files included.
"Access Denied" errors are most likely related to a configuration issue of the scan permissions. Please note that by default scans are executed in the context of the user account used as login for the SpaceObServer scan service ("SpaceObServer Agent"). Please ensure that this user has read permissions on the share you want to scan. In case the "local system" user is used, you may not have sufficient access permissions to network shares (See: "How can I switch the login..."). If you want to use a different user for scanning you can configure this account in the "Configure Scans" dialog.
SpaceObServer does not offer to run concurrent scans, but it performs each scan using many parallel threads. While developing SpaceObServer we compared concurrent scans and sequential scans. We learned that sequential scans which are internally parallelized provide the best performance while using minimal resources. One important reason for this is that a single scan highly benefits from caches. A SpaceObServer scan utilizes many caches: The file system cache, the SQL server in-memory cache, the CPU cache, and (for network scans) the SMB2 cache. The higher the locality of the executed code, the more efficiently those caches can be used.
