These differences can occur because of NTFS-specific features which are not recognized by the Windows Explorer.
UltraSearch recognizes compressed and sparse files as well as hard links. The new compression methods LZX and XPress, introduced with Windows 10, are supported with UltraSearch.
UltraSearch is optimized for fast searching and finding and offers a simple interface with quick access to the most important search functions, such as folder or file search, exclusion filter, date filter or file type search. The program is intended for "quick searches on demand" and indexes the file information in the system memory for this purpose, for lightning-fast results.
The TreeSize file search is much more flexible and offers you additional search options such as a duplicate search or the search for any metadata. Predefined search settings let you find duplicate, temporary or very large files.
The TreeSize file search not only offers versatile search options, but also offer in addition to the main module a great way to clean up your hard drive.
Starting with Windows Vista, Microsoft enforces more strict security rules on the operating system. One side effect of this is that you may not see your mapped network drives anymore (Windows 8 and later), or they all appear disconnected (typically in Windows Vista and 7) in applications that are running with administrator privileges.
This is because Windows uses different user environments for non-elevated and elevated processes. There are some workarounds to gain access to those network drives anyway:
If you want to use Regular Expressions to search for files, you can use the UltraSearch search syntax, by preceding the search term with a tilde ("~"), for example:
name: ~(?=.*help)|(?=.*online)
to search for all files that contain the word "help" or "online".
Context menu entries in Windows can differ depending on whether an application was started 'as administrator' or not. Since the Windows Explorer, unlike UltraSearch, is not started 'as administrator', there may be differences in the context menus.
You can start UltraSearch without administrative privileges by disabling the setting 'Options > Application > Always start as administrator'. However, this is not recommended because it prevents UltraSearch from accessing the MFT (Master File Table) and may slow down the search in UltraSearch.
You can observe the same behavior if you start the Windows Editor ('notepad.exe') by right-clicking and selecting 'Run as Administrator' and then selecting 'File > Open...'. In the file selection dialog shown, you can also open the Windows context menu with a right click. The entries you are looking for are also missing here.
Compressed files on an NTFS volume are shown in a blue color. Folders that are partially compressed will have a dark blue color, files and folders that are entirely compressed will show up in a light blue color. For more information on file-based compression see Notes on NTFS.
Yes. To be able to search even complex file types like Microsoft Word, Excel, or PowerPoint, UltraSearch uses the so-called IFilter interface, which is provided by the operating system. Third-party applications can also provide their own treatment routines that can be used to read certain file formats. Many file formats are already handled by the operating system's own routines.
In order to be able to search Office files, it may be necessary that a Microsoft Office version is installed on the system. Alternatively, the Microsoft Office Filter Pack can be installed.
UltraSearch is compatible with all Windows versions currently supported by Microsoft, including supported Windows Server versions (UltraSearch Professional Edition only). The latest patches and updates should be installed.
Yes. UltraSearch uses the so-called IFilter interface for full text search, which is provided by the operating system. To search PDF files, you need a filter for this file type, which is provided by Adobe, for example.
Many file formats, are already handled by the operating system's own routines.
There is also an article in our knowledge base about problems you may encounter when searching for file contents of PDF files.
If you want to search for all files with a certain file extension, use the prefix ext: or extension:, for example:
ext:txt
or just type *.txt
to search for all text files with the extension "txt".
