How to check that your bulk files downloads are correct:-
File size checking.
Some buttons show the file size in bytes, eg |
Once you have downloaded the file by clicking on the button, then on your computer, use either the 'File properties' (in windows) or 'File Info' on Mac computers to check the number of bytes.
This simple check should be sufficient to check that the download was successful. A better check, is to use the checksum calculation as detailed below.

MD5 File Checksum:
As an Internet standard (RFC 1321), MD5 has been used in a wide variety of security applications, and is also commonly used to check the integrity of file, and verify download. There are many free applications that calculate md5 hash or checksum for files on your PC.
Search on Google ( MD5 Checksum ) to find how it works etc, or:
For Window Users: Download free MD5 program from http://www.winmd5.com/
or at command line use FCIV (see here for details)
For Mac users: Download free program from http://md5.soft32.com/
or use MD5 command in terminal mode (see here for details)
