Code! How to read all txt documents in a folder in java including txt files in subfolders

Create a new class, name it FileHandler, put the following code into it, and set basePath to the folder path you want to read. Read and write methods have been provided and you can call them as needed. ```java import java.io.File; import java.io.FileWriter; import java.io.IOException; import java.nio.file.Files; import java.nio.file.Paths; public class FileHandler { private String basePath; public FileHandler(String basePath) { this.basePath = basePath; } public String readFile(String fileName) throws IOException { String filePath = basePath File.separator fileName; byte[] bytes = Files.readAllBytes(Paths.get(filePath)); return new String(bytes); } public void writeFile(String fileName, String

static String basePath="/home/csvDir";

/**

* Find all files in the folder that match csv

*

* @param dir The folder object to be found

**/

public static void findFile(File dir) throws IOException{

File[] dirFiles = dir.listFiles();

for(File temp : dirFiles){

if(!temp.isFile()){

findFile(temp);

}

//Find the specified file

if(temp.isFile() & temp.getAbsolutePath().endsWith(".txt") ){

System.out.println(temp.isFile() " " temp.getAbsolutePath());

readFileContent(temp);

}

}

}

/**

* @param file The file object to be read

* @return Returns the contents of the file

**/

public static String readFileContent(File file) throws IOException{

FileReader fr = new FileReader(file);

BufferedReader br = new BufferedReader(fr);

StringBuffer sb = new StringBuffer();

while(br.ready()){

sb.append(br.readLine());

}

System.out.println(sb.toString());

return sb.toString();

}

/**

* @param file The file object to be written

* @param content The content of the file to be written

**/

public static void writeFileContent(File file,String content) throws IOException{

FileWriter fw = new FileWriter(file);

fw.write(content);

fw.flush();

fw.close();

}

public static void main(String[] args) {

try {

findFile(new File(basePath));

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

High score code! How to use vba to retrieve all txt files in a folder containing

Sub t()

Dim fso, f, f1, fc, s, r

Const ForReading = 1, ForWriting = 2

Set fso = CreateObject("Scripting.FileSystemObject")

'Set fc = fso.GetFile(WScript.ScriptFullName).ParentFolder.Files

Set fc = fso.GetFolder("c:\windows").Files 'Change c:\windows to the actual folder when using it

L = 1

For Each f1 In fc

EXTName = UCase(fso.GetExtensionName(f1.Name))

If EXTName = "TXT" Then

Set fs = fso.OpenTextFile(f1, ForReading)

fb = fs.ReadAll

If InStr(1, fb,"Apple") > 0 Then

Cells(L, 1) = f1.Name

Cells(L, 2) = f1.Path

L = L 1

End If

End If

Next

End Sub
