Question

I’m working on moving some files to a different directory in my project and it’s working great, except for the fact that I can’t verify it’s moved properly.

I want to verify the length of the copy is the same as the original and then I want to delete the original. I’m closing both FileStreams before I do my verification but it still fails because the sizes are different. Below is my code for closing the streams, verification and deletion.

 in.close();
 out.close();

 if (encCopyFile.exists() && encCopyFile.length() == encryptedFile.length())
     encryptedFile.delete();

The rest of the code before this is using a Util to copy the streams, and it’s all working fine so really I just need a better verification method.

Answer 1

You could include a checksum in your copy operation. Perform a checksum on the destination file and see that it matches a checksum on the source.
