+# Partition Manager Tool (PMT)
+
+**Partition Manager Tool** is a fast, reliable, and feature-rich CLI application for **Android** devices that enables advanced partition operations such as backup, flashing, erasing, information retrieval, and more.  
+This **renovated edition**, written in modern **C++**, is faster, more stable, and more powerful than its previous versions, thanks to optimized multithreading and improved error handling.
+
+PMT is designed for developers, technicians, and Android enthusiasts who need fine-grained control over device partitions via a clean, flexible, and scriptable interface.

+## Key Features
+
+- **Backup** partitions to files (with permission adjustments for non-root access).
+- **Flash** image files directly to partitions.
+- **Erase** partitions with zero-byte filling.
+- **Retrieve** partition sizes in multiple units.
+- **Display** partition info (name, size, logical status) in text or JSON.
+- **Resolve** real block device paths and symbolic links.
+- **Identify** partition or image file types via magic number checks.
+- **Reboot** the device into multiple modes (normal, recovery, etc.).
+- **Asynchronous processing** for speed — each partition runs in its own thread.
+- **Error isolation** so one failing operation doesn’t cancel the rest. For back upping, flashing and erasing.
