* The function performs the following steps:

* 2. Opens the NPK archive and retrieves the number of contained files.
* 3. Iterates through each file entry in the archive, extracting its name, offset, and size.
* 4. Writes the file list to the output text file in tab-separated format: fileName, fileOffset, fileSize.
* 5. Closes all files and releases resources.
* 6. Returns true on success, or false if any error occurs during processing.
