our mission

Creating a modern file manager

The original file manager solution was outdated and difficult to maintain. The goal was to create a modern web application that works well on both desktop and mobile devices.

challenges

Performance optimization and complex UX

The challenges included optimizing application performance, virtualizing folder listings with thousands of items, and handling large amounts of events – file selection, drag and drop, context menus, and keyboard shortcuts. We also addressed the different behaviors between the mobile and desktop versions.

solution

Powerful and intuitive file manager

We designed a new web application that behaves similarly to a desktop file manager. Users can view files in a list or grid, manage file visibility, and share them with others. It also includes a tree navigation and breadcrumb bar.
