get a list of files???

[mackey333]

I need to write a program to remove duplicate files in 2 directories...i have literally hundreds of duplicate files and i dont want to go through manually and compare them..i need to free hd space so i am trying to write a program to accomplish this...i need a method that can put files in a directory into an array and then a method to delete a file..i also take it that once i get the files in an array i can compare with them with == to determine if they are the same??..thanks for any help -Greg :-Q

Look at the class File in java.io package.


File myDir = new File(<directory path>);

String[] myDirList = myDir.list();

This will return you a string array of all
file names in the directory.


Loop through the array of if you need to figure our
the file timestamp or size do as follows:



for ( i=0; i<myDirList.length; i++ )
{
File curFile = new File(myDirList);

Date lastMod = curFile.lastModified();
long size = curFile.length();

......

}

SDK 1.4 has handy classes for regular expression matching.
which may help to filter out fiels off the list.
