Get to know IDM UltraFinder

IDM UltraFinder is a file and text search program developed by IDM Computer Solutions, the same developer behind UltraEdit and UltraCompare. This program is created to help people who work with a large number of files, whether they are developers, technical writers, or system administrators who need to find where a specific word appears on their machine. Instead of opening files one by one to read through them, UltraFinder scans entire folders or drives and displays a list of matching files all at once.

The core of the program lies in searching for text inside files. Users can type the desired search term, select the destination folder, specify the desired file types, and the program will read the contents inside to find that word. It supports exact case-sensitive searches, case-insensitive searches, searches using special character patterns like Regular Expressions, and wildcard searches, which are ideal for tasks requiring words with similar spellings.

In addition to text search, UltraFinder can also search by file name, which is useful when you only remember part of the file name, or just the extension and the date range when the file was created or modified. Users can set detailed criteria such as file size, creation date, or last modified date, and the program will filter the results to show only files that match all criteria. The results are displayed in a table clearly showing the file name, location, size, and date. Clicking on any result allows you to instantly preview the content or open that file. Those who want to search for file names across the entire computer faster can try Everything which specifically searches by file name.

Another feature that sets UltraFinder apart from the Windows search bar is its flexibility in working with results. The program saves search history to recall for later use, saves frequently used criteria as presets, and exports results for further use. Search results can be sent directly to UltraEdit to edit text within that file.

Therefore, UltraFinder is suitable for tasks that regularly require managing a large number of files, such as searching for old code in projects, checking which documents contain text that needs editing, and tracking down files that have been moved or renamed. It is not a file editor, but a search tool that helps you find the files you need faster and get a clearer overview of the data on your machine.

Who is this program suitable for?

UltraFinder is ideal for developers who need to search for old code in projects, system administrators who need to track down configuration files or log files across the machine, and people who work with numerous documents and cannot remember which file contains important text. These tasks require searching inside thousands of files, which a normal search bar does poorly or cannot do at all. For those who just need to occasionally open music or image files, the Windows search bar is sufficient.
