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 a file content search, the application uses the file handlers that are registered in Windows. The same technology is used by Windows Explorer, for instance (you could reproduce this issue in Windows Explorer as well). It is a known issue with Windows' preinstalled PDF file handler in combination with certain PDF files.

What you can do as a workaround is to install a different, third party file handler for PDF files, such as the one from Adobe (https://www.documentlocator.com/downloads/software/PDFFilter64Setup.msi).

For fast search results UltraSearch does not use an index but uses the working memory (RAM) to store the file information. Depending on the number of files and folders on your hard drive, this can be several hundred MB. 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".
You can find further information in the UltraSearch Help in the chapter "Installation".

For the freeware UltraSearch Free we offer the portable version as a zip file for download on our website.

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