Java 消除文件目录结构

List<File> list=allFile(targetPath);

for(File each:list)

{

File file=new File(targetPath+File.separator+each.getName());

each.renameTo(file);

}

//删除空文件夹

File dir= new File(targetPath);

for(File eaFile:dir.listFiles())

{

if(eaFile.isDirectory())

{

eaFile.delete();

}

}

private List<File> allFile(String path)

{

File targetDir=new File(path);

List<File> list=new ArrayList<File>();

for(File each:targetDir.listFiles())

{

if(each.isDirectory())

list.addAll(allFile(each.getPath()));

else

list.add(each);

}

return list;

}
