删除文件夹(前提:文件夹为空以及InputStream和OutputStream等一些数据文件流关掉【close()】,否则文件无法删除)
- //删除文件夹
- public static void delFolder(String folderPath) {
- try {
- delAllFile(folderPath); //删除完里面所有内容
- String filePath = folderPath;
- filePath = filePath.toString();
- java.io.File myFilePath = new java.io.File(filePath);
- myFilePath.delete(); //删除空文件夹
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
删除指定文件夹下的所有文件
- public static boolean delAllFile(String path) {
- boolean flag = false;
- File file = new File(path);
- if (!file.exists()) {
- return flag;
- }
- if (!file.isDirectory()) {
- return flag;
- }
- String[] tempList = file.list();
- File temp = null;
- for (int i = 0; i < tempList.length; i++) {
- if (path.endsWith(File.separator)) {
- temp = new File(path + tempList[i]);
- } else {
- temp = new File(path + File.separator + tempList[i]);
- }
- if (temp.isFile()) {
- temp.delete();
- }
- if (temp.isDirectory()) {
- delAllFile(path + "/" + tempList[i]);//先删除文件夹里面的文件
- delFolder(path + "/" + tempList[i]);//再删除空文件夹
- flag = true;
- }
- }
- return flag;
- }
- }
