1. General Program Description
The program "TGA File Sorter" is designed for automatically sorting TGA (Truevision Targa) images by their bit depth and alpha channel presence. It analyzes each file in the selected folder, determines its format (24-bit or 32-bit), and checks for the presence of an alpha channel in 32-bit files. The program then sorts the files into the corresponding subfolders:
- TGA 24bit (BGR)
- TGA 32bit (with alpha) (BGRA)
- TGA 32bit (without alpha) (BGRX)

The program also keeps a detailed log of the process, saves statistics, and allows canceling the operation at any time.

2. System Requirements
- Operating System: Windows 7/10/11 (x64 or x86)
- .NET Framework: 4.7.2 or higher
- Processor: 1 GHz or higher
- RAM: 512 MB (1 GB recommended)
- Disk Space: Depends on the size of the files being processed (at least 10 MB for the program)
- Screen Resolution: 1024×768 or higher

3. Program Features
Main Features:
- Select a folder for processing via the standard Windows dialog.
- Automatic sorting of TGA files by bit depth and alpha channel presence.
- Asynchronous processing support with the ability to cancel the operation.
- Progress bar to track task completion.
- Detailed real-time logging with results saved in a file (log folder).
- Alpha channel check for 32-bit files (accurate pixel analysis).
