Packing
NiceProtect can reduce the growth of the executable file's size after its protection. For that end, NiceProtect can pack the file with a built-in packer.
In addition to its main function, the packer supports resources encryption and file optimization. The packer algorithm, which will be embedded into your application, also contains tools to make unauthorized unpacking more difficult in order to reduce the risks of your application being cracked.
Such packing is very useful, because otherwise virtualizing an executable file can greatly increase it size. By packing the file, you can keep its size almost as before virtualization.
