In order to quickly find files and folders on your hard drive, UltraSearch directly accesses the Master File Table of local NTFS partitions. Administrator rights are needed for this. As a consequence the User Account Control (UAC) is displayed. You can skip this dialog by disabling Skip User Account Control Warning via Options > Application.
If you want to search for file content, use the prefix cont: or content: , for example:
to search all files with the word "license" in its content.
If you prefer to use separate input fields for entering file contents as in earlier UltraSearch versions, you can also use the Query Composer on the 'Start' or 'Search' tab.
The full text search is time-consuming. It is therefore recommended to use additional search criteria like file name or file extension.
You can start UltraSearch directly with the operating system via 'Options > Application > Launch at Windows startup'. UltraSearch is then always available from the notification area on the right side of the taskbar.
The key combination 'Ctrl + Shift + U' can bring UltraSearch to the foreground at lightning speed and you can start your search without delay. You can change the key combination for launching UltraSearch at any time under 'Options > Application > Select hotkey'.
This is a known issue with Windows' preinstalled PDF file handler in combination with certain PDF files.
In order to be able to read the content of certain files, our software uses file handlers that are registered in Windows. Unfortunately, there seems to be an issue with Microsoft's PDF file handler, which causes this behavior in rare cases.
The same technology is also used by Windows' File Explorer (you could reproduce this issue in File Explorer as well). 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.
This error code indicates that the root certificate is not trusted on the system. We just recently updated the certificate we used to sign our applications, so it still seems to be the case that this root certificate is not yet up to date.
These certificates are usually being updated and installed online and/or along with Windows updates. These updates might be disabled manually though.
Please check for pending or available Windows updates first.
If this doesn't work, please try to download and install the updated certificates manually. They are issued from GlobalSign and should therefore be considered safe:
Root certificate https://secure.globalsign.com/cacert/codesigningrootr45.crt
Intermediate certificate https://secure.globalsign.com/cacert/gsgccr45evcodesignca2020.crt
Please ensure to install the root certificate to the correct store (root certificates). Having Windows select the store automatically, it might select the wrong store for this certificate.
In general, not every file type can be previewed but Office files, PDF documents, text files and most similarly popular formats are supported.
If the preview is not working, please try to start the application without administrator rights first and also check if the preview works in the Windows Explorer (which has its own, similar preview once you enabled it there).
