It's a component that allows you to store files by arbitrary ID.
Instantiate the FileStore class with a base path and manipulate content referenced by ID:
fileStore = new FileStore(path);
String id = "myarbitraryid";
// Create
FileInputStream content1 = new FileInputStream(file1);
fileStore.create(id, content1);
// Read
InputStream stored = fileStore.read(id);
// Update
FileInputStream content2 = new FileInputStream(file2);
fileStore.update(id, content2);
// Delete
fileStore.delete(id);
