   // System.out.println("About to delete an entry from ZIP File" +

Answer 1

在文件中使用delete（）方法之后。 filePath是一个字符串，其中包含zip文件的路径。

File file = new File(filePath);

//必须检查删除是否为真。如果文件已成功删除，则为真

boolean deleted = file.delete();

Answer 2

 Use below method

     /**
     * Clear/Delete all the contents in file/Directory
     *
     * @param file file/folder
     * @return true on successfull deletion of all content
     * <b>Make sure file it is not null</b>
     */
    public boolean clearDirectory(@NonNull File file) {
        boolean success = false;
        if (file.isDirectory())
            for (File child : file.listFiles())
                clearDirectory(child);
        success = file.delete();
        return success;
    }

Answer 3

尝试一下！

public static final String ZIP_FILES_DIR = "Download/FolderNAME";    

File directoryPath = new File(Environment.getExternalStorageDirectory()+ File.separator + ZIP_FILES_DIR);
    if (directoryPath.delete()) {
        //do whatever you want
      }

Answer 4

File file = new File（deleteFilePath）; 布尔值删除= = file.deleted（）;

deleteFilePath是一个字符串，其中包含您的zip文件的路径。

如果删除为true。如果文件已成功删除，则为真。
