CP5 error TooManyFiles for Zip.Add

SOLVED

Upgrading to v13.1 SageCRE300 Estimating - when backing up DBs it returns CP5 error TooManyFiles for Zip.Add and ends backup - Incomplete.  Not a space issue.  Validates the available space 825MB for backup and 96GB available.

Checked knowledgebase and only shows CP5 error - Not enough available space and the other is permissions issue. Neither apply.

It did back up 2 other DBs to the same location without any issue. I tried to include less files from the same DB and get the same 

CP5 error TooManyFiles for Zip.Add error.

Any help would be appreciated.

Thank you.
