This problem is unfortunately caused by SharePoint itself.
SharePoint throttles the number of user actions for very large requests. This leads to the fact that TreeSize has to pause the scan after a certain number of calls for a short time (40 to 300 seconds) until new user requests are released.
If SharePoint interrupts the active scan due to too many calls, a message is written in the Windows Event Viewer that refers to the throttling.
To speed up or not unnecessarily slow down a scan, unused statistics (esp. the statistics on file owners and the option to 'Track advanced file system features') should be deactivated.
As an alternative, SpaceObServer may be interesting for you, as it also supports SharePoint scans. Due to the database used to persist the scan results, the data collecting process, and the reporting/analysis can be split up into two independed steps. Let the scan-service wait, instead of waiting yourself.
We discussed this behavior with several NAS vendors, who agreed that this is an issue with the SMB implementation of the specific NAS system.
Please check if there is an update available for your NAS and if it resolves this issue for you. If not, please contact the vendor of your NAS system and ask him to fix this behavior.
As a workaround in TreeSize, you can activate a legacy mode, where TreeSize would estimate the allocated values based on the sizes. To do so, please start TreeSize with the parameter: /UseLegacyEnumerator True
When deduplicating files, TreeSize replaces duplicate files by hard links, after which the physical data exists only once on the hard disk. There are however X links to this data. Each of these links is shown with the size of the physical data, this is why the Windows Explorer and by default also TreeSize shows the same size for these files and the folders they are included in.
If you take a look at the allocated space of the physical drive (e.g. in the "Drive List" in TreeSize or in the "Properties" of the drive in the Windows Explorer) you will notice the difference.
To get the correct physically allocated size of a folder, you need to look at the column "Allocated Space". In the TreeSize main application make sure that the option "Track NTFS alternate data streams and NTFS hardlinks" is turned on in the Options dialog.
Open the TreeSize File search using the Windows Start menu or the TreeSize Tools menu, add the network paths to the list of paths to Search, activate the Duplicate Search only and start the search. You may change the way TreeSize compares the files on the "Duplicate Files" tab.
Yes. And Long path can be explicitly searched for using the Advanced Search. Simply select the template "Files with long paths".
What you can do is using the Custom Search type of the TreeSize File Search. It allows to search the entire network or IPv4 address ranges for certain files, like *.pst. Simply specify \\* or \\192.168.123.* as path to search. TreeSize will then enumerate all available PCs in e network or that IPv4 network segment and search their drives (or more exactly: their public and hidden shares) for the files matching the search criteria.
Yes, the TreeSize File Search can search, report and delete or move files over a certain age. You can select the template "Modified long time ago" in the custom search, to load a search configuration for old files. Check the files you want to delete and use the "Delete" button to delete or move them to the Recycle Bin. You can schedule this search and also automate a move or delete operation, by using the option "Tools > Schedule current search".
Unfortunately there is no short and easy answer to this question because usually one cannot know where a file came from and what it is used for. Generally temporary files and cache files of the internet browsers can nearly always be deleted safely. Besides deleting files, the File Search of the software offers you to move files to a different drive or to a compressed ZIP file (preserving the file system hierarchy) which can then be archived. That way files that are still needed can be easily restored, either manually or by using the restore script that the software is able to generate optionally.
To check all results, click on "Check All". To check some results based on their name, use the "Check if" button. You may select multiple files using a left mouse click while holding the <Shift>- or <Ctrl>-key down. Using "Check" from the context menu checks all currently selected files.
The duplicates search offers additional useful options to check specific files in each duplicates group, such as "All but the newest"
Yes. Please open the TreeSize File Search via the Windows "Start" menu or the TreeSize "File Search" menu, check the drives that should be searched and click "Select template". Select "Modified long time ago" and adjust the date filter value. You can also change your filters, or add more, if you need a more custom set of filter options.
After setting up the search options, hit the "Start" button. After the search has completed, check mark all files that you want to archvie and click "Move", or "Archive" in the "Operations" tab. The file operations dialog will allow to specify the option to preserve the directory structure, as well as creating a log file of the operation.
