+### Script for rename multiple files
+
+Tested in Python version 3.11.2, but it must working in version 3.5 and above.
+
+### Run
+
+GNU\Linux: `$(which python3) main.py`
+
+Windows: `C:\\Path\\to\\Python3\\Python3.exe main.py`
+
+Folders structure:
+
+```
+main.py
+root/
+   |
+   |--- folder1
+   |          |
+   |          |- file1.txt
+   |          |- file2.txt
+   |          |- file2.txt
+   |
+   |--- folder2
+   |          |
+   |          |- file1.txt
+   |          |- file2.txt
+   |          |- file2.txt
+   |
+   |--- folder3
+   |          |
+   |          |- file1.txt
+   |          |- file2.txt
+   |          |- file2.txt
+```
+
+Output files structure:
+
+```
+folder1/folder1-1.txt
+folder1/folder1-2.txt
+folder1/folder1-3.txt
+
+folder2/folder2-1.txt
+folder2/folder2-2.txt
+folder2/folder2-3.txt
+
+folder3/folder3-1.txt
+folder3/folder3-2.txt
+folder3/folder3-3.txt
+```
+
+Maybe set outher symbol for `DESTINATION_FILE_DELIMITER` param or just leave blank `DESTINATION_FILE_DELIMITER = ''`

+
+### Скрипт для переименования большого количества файлов
+
+Тестировался на Python версии 3.11.2, но должен работать на версиях выше 3.5.
+
+### Запуск
+
+GNU\Linux: `$(which python3) main.py`
+
+Windows: `C:\\Path\\to\\Python3\\Python3.exe main.py`
+
+Структура папок:
+
+```
+main.py
+root/
+   |
+   |--- папка1
+   |         |
+   |         |- файл1.txt
+   |         |- файл2.txt
+   |         |- файл2.txt
+   |
+   |--- папка2
+   |         |
+   |         |- файл1.txt
+   |         |- файл2.txt
+   |         |- файл2.txt
+   |
+   |--- папка3
+   |         |
+   |         |- файл1.txt
+   |         |- файл2.txt
+   |         |- файл2.txt
+```
+
+Скрипт переименует файлы в папках так:
+
+```
+папка1/папка1-1.txt
+папка1/папка1-2.txt
+папка1/папка1-3.txt
+
+папка2/папка2-1.txt
+папка2/папка2-2.txt
+папка2/папка2-3.txt
+
+папка3/папка3-1.txt
+папка3/папка3-2.txt
+папка3/папка3-3.txt
+```
+
+В случае необходимости можно поменять `DESTINATION_FILE_DELIMITER` на нужный символ или вообще оставить пустым `DESTINATION_FILE_DELIMITER = ''`
