Large Text File Reader

Large Text File Reader is a lightweight software application designed to open large text documents to show their contents. It does so by opening only a specific number of lines, in order to prevent Windows from hanging and crashing. Up to 10GB size is supported.

The whole program is wrapped in a single executable file that can be saved in a custom location on the disk, in order to seamlessly launch the tool. Otherwise, you can keep it stored on a USB flash drive to run it on any PC with minimum effort.

However, you must have .NET Framework installed, since it was developed using this platform. No additional files are created on the disk without your permission, and no changes are made to the Windows registry as a direct consequence of using this tool.

It's packed in a user-friendly interface represented by a standard .NET Framework form that doesn't put emphasis on graphical elements. It lists a handful of options, enabling you to locate and open a text file, set the number of lines to display, and view contents.

Although there are no buttons implemented for copying data to the Clipboard, printing or exporting it to file, you can select text and copy it using the global hotkey or by opening the right-click menu. There are no other notable options available here.

It worked smoothly in our tests, without freezing, crashing or showing errors. We haven't come across any stability issues. As we expected, it didn't put a strain on the computer's performance, running on a low amount of CPU and RAM.

Although it doesn't have richer features, Large Text File Reader offers a straightforward solution for opening large text documents, and it can be handled with ease.
