Thread: Access Denied when extracting zip file.

I'm attempting to create an installer of sorts. When created, everything is stored inside a zip file named DATA.mpk and then put inside the jarfile for distribution.

The structure looks like this

Jar.jar
--DATA.mpk
----INJAR
------files
----mc
------files
--classes


Here's my current extraction code:

//DATA.mpk
			System.out.println(dataDir.canRead() + ":" + dataDir.canWrite() + ":" + dataDir.canExecute());
			try
			{
				//gimme
				copyInputStream(Extractor.class.getResourceAsStream("DATA.mpk"), new BufferedOutputStream(new FileOutputStream(".DATA.mpk")));
 
				//nowgo
				ZipFile zipFile = new ZipFile(".DATA.mpk");
 
				Enumeration<? extends ZipEntry> entries = zipFile.entries();
 
				while(entries.hasMoreElements()) {
					String path = "DATA/";
					ZipEntry entry = (ZipEntry)entries.nextElement();
					if(!entry.getName().contains("META-INF")){
						File file = new File(entry.getName()); 
						try{
							if(file.getParent() != null);
							StringBuilder finalPath = new StringBuilder();
							finalPath.append("DATA/");
							String[] structure = entry.getName().split("/");
							for (int i=0; i<structure.length -1; i++){
								finalPath.append(structure[i]).append("/");
							}
							File parentDir = new File(finalPath.toString());
							parentDir.mkdirs();
						}catch(Exception e){
 
						}
 
						System.out.println("Extracting datafile: " + entry.getName());
						copyInputStream(zipFile.getInputStream(entry), new BufferedOutputStream(new FileOutputStream(path + entry.getName())));
					}else{
						continue;
					}
				}
				zipFile.close();
 
			}
			catch (Exception e)
			{
				e.printStackTrace();
				return false;
			}
			File df = new File("DATA.mpk");
			df.delete();

According to the debug line, I have read/write/execute permissions on the directory, but when it attempts to extract the INJAR folder, it throws FileNotFoundException (Access is denied).

Not sure where the issue is. There's a clause before the above code that successfully unzips a jarfile already on my computer, I'm adding stuff to it using the above clause and then re-zipping everything up.

Here's the exact error:
