import Foundation

func moveFileToPermanentDirectory() {
    let temporaryPath = NSTemporaryDirectory()
    let permanentPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
    
    let fileManager = FileManager.default
    
    do {
        let files = try fileManager.contentsOfDirectory(atPath: temporaryPath)
        
        for file in files {
            let temporaryFilePath = temporaryPath.appendingPathComponent(file)
            let permanentFilePath = permanentPath.appendingPathComponent(file)
            
            try fileManager.moveItem(atPath: temporaryFilePath, toPath: permanentFilePath)
            
            print("File moved to permanent directory: \(permanentFilePath)")
        }
    } catch {
        print("Error moving file: \(error)")
    }
}
