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".

For fast search results UltraSearch does not use an index but uses the working memory (RAM) to store the file information. UltraSearch uses between 40 and 50 MB of RAM per 100,000 files/folders. In order to keep the amount of RAM required as small as possible, please select only the drives or folders you want to search in the drive list. If you deselect a drive, the file information for this drive will be deleted directly from the working memory.

Yes. The full version of UltraSearch Professional offers the possibility to create your own portable version. To do this, UltraSearch Professional must first be installed on a PC. Then start UltraSearch Professional and select "Options > Create portable installation".

For the freeware UltraSearch Free we offer a separate download of the portable version.

UltraSearch does not support relative paths or URLs in the drive list. Specified paths must be clearly related to a drive, for example 'C:\Users\Default\Downloads' rather than 'Downloads'.

In order to move the UltraSearch settings to a new PC, please navigate to the '%AppData%\JAM Software' directory and copy the subfolder 'UltraSearch' to the corresponding folder on the new PC. If the '%AppData%' folder on the new PC does not contain a subfolder called 'JAM Software', please create it manually.

When searching for file content, UltraSearch analyzes the entire content of each file, so it has to open each file and match its content with the search term. Because file content is not stored in UltraSearch's internal cache, searching may be slower on drives with many or large files, or on network drives. To speed up the file content search, the search should be further restricted using additional search criteria. For example, by restricting it to a specific drive or folder. Restricting to a specific file type or entering parts of the file name is also useful. Additional restrictions through exclusion filter or date and size filters also help to speed up the search.
