Question

I have the below code which checks to see if folder exists on the sdcard, I would like to add another if statement if the folder exists to check that there are zip files inside the actual folder if it in fact exists. What could i do to check the folder for a zip extension. The folder should have a lot of zips in it but i only want it to check to make sure there are zips and no other file extension. I thank you for any help with this.

File z = new File("/mnt/sdcard/folder");
if(!z.exists()) {
Toast.makeText(MainMethod.this, "/sdcard/folder Not Found!", Toast.LENGTH_LONG).show(); 
} else {
Toast.makeText(MainMethod.this, "/sdcard/folder Found!", Toast.LENGTH_LONG).show();
}

EDIT:
Thanks guys for the help here is what i ended up using with your help, i haven’t tested it yet but it looks good to me.

    File z = new File("/mnt/sdcard/Folder");
    if(!z.exists()) {
           //create folder
} else {
        FilenameFilter f2 = new FilenameFilter() {
        public boolean accept(File dir, String filename) {
        return filename.endsWith("zip");
        }
        };
            if (z.list(f2).length > 0) {
            // there's a zip file in there..
            } else {
            //no zips inside folder
        }
    }

Answer 1

File f = new File("folder");
FilenameFilter f2 = new FilenameFilter() {
public boolean accept(File dir, String filename) {
return filename.endsWith("zip");
}
};
if (f.list(f2).length > 0) {
// there's a zip file in there..
}

Try the above..
