The list of methods to do Folder Read Recursive are organized into topic(s).

Method

List getFiles(File dir, String excludeFiles, boolean includeFiles, boolean includeDirs, boolean recursive, List filelist)
Recursive function to descend into the directory tree and find all the files and directories excluding those specified by exclude.

File listFile[] = dir.listFiles();
if (listFile != null) {
 for (int i = 0; i < listFile.length; i++) {
 if (!excludeFile(listFile[i].getName(), excludeFiles)) {
 if (listFile[i].isDirectory()) {
 if (includeDirs) {
 filelist.add(listFile[i]);
 if (recursive) {
 filelist = getFiles(listFile[i], excludeFiles, includeFiles, includeDirs, recursive,
 filelist);
 } else {
 if (includeFiles)
 filelist.add(listFile[i]);
return filelist;

List getFiles(File directory, boolean recursive)
Get all files in a directory

List<File> fileList = new ArrayList<File>();
if (!directory.isDirectory()) { 
 fileList.add(directory);
 return fileList;
File[] files = directory.listFiles();
for (File f : files) {
 if (f.isDirectory()) {
...

List getFiles(File directory, boolean recursive)
get Files

if (!directory.isDirectory()) {
 throw new AssertionError(directory + " is not a directory!");
List<File> files = new ArrayList<>();
for (File f : directory.listFiles()) {
 if (f.isDirectory() && recursive) {
 files.addAll(getFiles(f, recursive));
 } else {
...

ArrayList getFilesAsArrayListRecursive(String path)
get Files As Array List Recursive

ArrayList<String> mFileList = new ArrayList<String>();
File root = new File(path);
getFilesAsArrayListRecursiveHelper(root, mFileList);
return mFileList;

void getFilesAsArrayListRecursiveHelper(File f, ArrayList filelist)
get Files As Array List Recursive Helper

if (f.isDirectory()) {
 File[] childs = f.listFiles();
 for (File child : childs) {
 getFilesAsArrayListRecursiveHelper(child, filelist);
 return;
filelist.add(f.getAbsolutePath());
...

void getFilesByNameRecursive(Collection filesList, File path, String name)
Get all files existing in the path with the specified name.

for (final File file : path.listFiles()) {
 if (file.isFile() && file.getName().equals(name)) {
 filesList.add(file);
 } else if (file.isDirectory()) {
 getFilesByNameRecursive(filesList, file, name);

List getFilesForFolder(File folder, boolean recursive)
Returns a sorted list of files contained in the directory.

List<File> fileList = new ArrayList<File>();
listFilesForFolder(fileList, folder, recursive);
Collections.sort(fileList);
return fileList;

File[] getFilesParent(File dir, String excludeFiles, boolean includeParentDir, boolean includeFiles, boolean includeDirs, boolean recursive)
This is the initial parent to getFiles.

File[] files = null;
List<File> filelist = new ArrayList<File>();
filelist = getFiles(dir, excludeFiles, includeFiles, includeDirs, recursive, filelist);
if (includeParentDir) {
 files = new File[filelist.size() + 1];
 files[0] = dir;
 for (int i = 0; i < filelist.size(); i++) {
 files[i + 1] = filelist.get(i);
...
