Share a small program to clean up garbage in memory cards and USB flash drives

There is a scenario where the phone’s memory card space is used up, but I don’t know which file is taking up too much. It’s too troublesome to find each folder, so I developed a small program to store all the files on the phone (including Files under all subfolders under the path) are sorted so that you can find out which file takes up too much memory.

The usage example is as follows, use JAVA to run Sort

1, and enter the path of the files you want to sort. For example, the example is to process the files under H:\ and the files under all its subfolders. Sort

2. Enter the latest size that needs to be sorted and displayed. For example, the example is to sort files above 10M in size

3. Sort from large to small and press

File path\file name-------Size KB--------Creation date is displayed (yyyyMMdd)

format is displayed.

This way you can delete files that are too large and clear up space

D:\hjbsSorft\work\20140207\SortSize\bin>java com.he.jinbin.Sort
Enter the address of the file to be sorted: H:\
Enter the size of the file to be sorted (unit M): 10
Running, please wait...
Sort files from large to small as:

The disadvantage of Windows is that it cannot display the size of the folder.

Although simple, my personal opinion is that programs are just tools. A good program is a program that brings convenience to life. It is not for showing off technology, just for practicality
