If using to create smaller files to migrate into Noah ES it is VERY important that the file size of each split file should be set to 50 MB. The default is 50 MB. Trying to create larger files is not recommended for Noah ES
Make sure to read all of the information on using the Noah ES Migration Utlility - in this case the advanced tab/mode is what will be used to migrate many smaller files
How to Use
Usage: NhaxFileSplit [-s <no>] [-o <path>] [-p <text>] [-pi <passwd>] [-po <passwd>] <input file>
-o Path to output directory, default is the path to exe file
-p. FilePrefix for created files. The format is <prefix>.000001.Nhax or ENhax. Default Split
-pi Password used if input file is password protected
-po Output file will be password protected using the given password
-s When size (measured in bytes) of output file larger than size a new Nhax file is written. Default 52428800
The program reads a nhax file and split the file into a number of files.
