Java Delete files Note: 1. The path can not appear on the Java illegal characters, such as "(,"), etc.;

2. Ensure that files are not used until the deletion is done, that is, the file resources are freed.

What to delete when you delete files and folders in Java:

1. Documents in the folder;

2. Folders inside the folder (with files);

3. Folder inside the subfolder (empty folder);

public class DeleteFile {
Delete Folder
param folderpath folder Complete absolute path

public static void Delfolder (String folderpath) {
try {
Delallfile (FolderPath); Delete all contents inside
String FilePath = FolderPath;
FilePath = Filepath.tostring ();
File Myfilepath = new file (FilePath);
Myfilepath.delete (); Delete empty Folder
catch (Exception e) {
E.printstacktrace ();
}
}

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])//delete files in folder first
Delfolder (path + "/" + templist[i])//Delete empty folder
Flag = true;
}
