Java Utililty Methods Zip Directory

void addDirectoryToZip(File directory, File base, String dirPrefix, ZipOutputStream zos)
Recursively inserts all files in a directory into a zipstream.

if (base == null)
 base = directory;
if (dirPrefix == null)
 dirPrefix = "";
if (!base.equals(directory) && directory.list().length == 0) {
 String dirEntryPath = dirPrefix
 + directory.getPath().substring(base.getPath().length() + 1).replace('\\', '/');
 ZipEntry dirEntry = new ZipEntry(dirEntryPath.endsWith("/") ? dirEntryPath : dirEntryPath + "/");
...

void addDirectoryToZip(ZipOutputStream out, File dir, String prefix)
add Directory To Zip

FileInputStream in;
byte[] buf = new byte[1024];
int len;
if (dir.isDirectory()) {
 for (File f : dir.listFiles()) {
 if (f.isDirectory()) {
 addDirectoryToZip(out, f, ("".equals(prefix) ? "" : prefix + "/") + f.getName());
 } else if (f.isFile()) {
...

void addDirectoryToZip(ZipOutputStream zipOutputStream, File dirToZip, String basePath, File fileToExclude)
Add the content of a directory recursively to the zip.

for (File file : dirToZip.listFiles()) {
 if (file.isDirectory()) {
 addDirectoryToZip(zipOutputStream, file, basePath, fileToExclude);
 } else if (!file.equals(fileToExclude)) {
 addFileToZip(zipOutputStream, file, basePath);

void addDirectoryToZip(ZipOutputStream zipOutputStream, String dirName)
Adds a directory to a .zip file

zipOutputStream.putNextEntry(new ZipEntry(dirName));
zipOutputStream.closeEntry();

void addDirToArchive(ZipOutputStream zop, File srcFile)
Helper method that aids zipRollbackPackage in recursively creating a zip file from a directory's contents.

File[] files = srcFile.listFiles();
for (File file : files) {
 if (file.isDirectory()) {
 addDirToArchive(zop, file);
 continue;
 byte[] buffer = new byte[1024];
 FileInputStream fis = new FileInputStream(file);
...

void addDirToArchive(ZipOutputStream zos, File srcFile)
Adds file / folder to zip output stream.

File[] files = srcFile.listFiles();
for (int i = 0; i < files.length; i++) {
 if (files[i].isDirectory()) {
 addDirToArchive(zos, files[i]);
 continue;
 try {
 byte[] buffer = new byte[1024];
...

void addDirToArchive(ZipOutputStream zos, String path, File initialDir)
Add a directory to a ZIP archive

File srcDir = new File(path);
File[] files = srcDir.listFiles();
for (int i = 0; i < files.length; i++) {
 try {
 String relativePath = initialDir.toURI().relativize(files[i].toURI()).getPath();
 zos.putNextEntry(new ZipEntry(relativePath));
 boolean emptyDir = files[i].isDirectory() && files[i].length() == 0;
 if (!emptyDir) {
...

void zip(File dir, File base, ZipOutputStream out)
zip

File[] files = dir.listFiles();
byte[] buffer = new byte[8192];
final String FILE_SEP = System.getProperty("file.separator");
for (int i = 0; i < files.length; i++) {
 if (files[i].isDirectory()) {
 zip(files[i], base, out); 
 } else {
 FileInputStream fin = new FileInputStream(files[i]);
...

void zip(File dir, ZipOutputStream out, String prefix)
zip

File[] files = dir.listFiles();
for (File f : files) {
 if (f.isFile()) {
 BufferedInputStream bis = null;
 try {
 bis = new BufferedInputStream(new FileInputStream(f));
 ZipEntry entry = new ZipEntry(prefix + f.getName());
 out.putNextEntry(entry);
...

void zip(File dir2zip, File zipFile)
zip

ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(zipFile));
internalZipDir(dir2zip.getAbsolutePath(), dir2zip.getAbsolutePath(), zos);
zos.close();
