Check if a path represents a file or a folder

Question

I need a valid method to check if a String represents a path for file or a directory. What are valid directory names in Android? As it comes out, folder names c

Answer 1

String path = "Your_Path";
File f = new File(path);

if (f.isDirectory()){



  }else if(f.isFile()){



  }

Answer 2

To check if a string represents a path or a file programatically, you should use API methods such as isFile(), isDirectory().

How does system understand whether there's a file or a folder?

I guess, the file and folder entries are kept in a data structure and it's managed by the file system.

Answer 3

public static boolean isDirectory(String path) {
    return path !=null && new File(path).isDirectory();
}

To answer the question directly.

Answer 4

Clean solution while staying with the nio API:

Files.isDirectory(path)
Files.isRegularFile(path)

Answer 5

   private static boolean isValidFolderPath(String path) {
    File file = new File(path);
    if (!file.exists()) {
      return file.mkdirs();
    }
    return true;
  }

Answer 6

Please stick to the nio API to perform these checks

import java.nio.file.*;

static Boolean isDir(Path path) {
  if (path == null || !Files.exists(path)) return false;
  else return Files.isDirectory(path);
}
