Question

I have a folder which contains some files that I want to deleted after processing them. The files have the extension .FIR After some googling I found a recursive method that I modified a bit:

void delete(File f) throws IOException {
      if (f.isDirectory()) {
        for (File c : f.listFiles())
            if(f.listFiles().toString().contains(".FIR"))
                delete(c);
      }
      if (!f.delete())
        throw new FileNotFoundException("Failed to delete file: " + f);
    }

This function will throw an IOException telling me:

07-31 11:02:31.885: E/DELETE:(5694): Failed to delete file: /mnt/sdcard/ExtractedFiles

The folder has been set to RW operations. And in my manifest file:

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I couldn’t find another permission that sounded something like MODIFY_FILES

Any ideas?

try this:

void delete(File f) throws IOException {
    if (f.isDirectory()) {
        for (File c : f.listFiles()) {
            delete(c);
        }
    } else if (f.getAbsolutePath().endsWith("FIR")) {
        if (!f.delete()) {
            new FileNotFoundException("Failed to delete file: " + f);
        }
    }
}
