## Description

This application is a cross-platform desktop utility designed to manage and accelerate file transfers. Built using the Kotlin programming language, it provides a consistent interface for tracking, pausing, and resuming downloads across different operating systems.

The software distinguishes itself by intercepting download requests directly from web browsers through a dedicated messaging protocol. It optimizes transfer speeds by splitting files into multiple segments, which are then downloaded concurrently to maximize available network bandwidth. To ensure data reliability, the manager performs checksum-based integrity verification on completed files to detect potential corruption.

The application includes comprehensive tools for organizing and controlling network traffic. Users can manage download queues through priority-based scheduling, allowing for the execution of transfers in specific sequences or at designated times. Persistent state serialization ensures that active download metadata is saved locally, enabling the resumption of interrupted tasks after an application restart.
