Delete Files from directory based on directory size.

Dannible · by **Dannible** » Fri May 14, 2010 4:46 pm

In my application I have a directory where I keep images temporarily. I would like to be able to delete the images from this directory when it reaches a certain size. I don't need it to delete the oldest first or anything like that. I just need to keep the size in check.

This is what I have:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public void DelSomeCache(Long dirSize){
 
                long dirFileSize = 0;
 
                String sDir = Environment.getExternalStorageDirectory()+"/myDir";
 
                File delDir = new File(sDir);   
 
                String[] files = delDir.list();
 
                for(int i=0;i<files.length;i++){
 
                        File ftdel = new File(files[i]);
 
                        long fileSize = ftdel.length();
 
                        dirFileSize = dirFileSize + fileSize; 
 
                        if(dirFileSize>=dirSize){
 
                                Log.i("Deleted",files[i]);
 
                                ftdel.delete();
 
                        }
 
                }
 
        }

It does not seem to be working. I get a message in the LogCat that files were deleted, but when I check the files are still there. Any help with what i'm missing would be appreciated.
