There is only one file type that uses the .NOY extension:
NOY Backup File
A NOY file is a backup file created by NOY Backup Utility, a program used to create compressed backups of files. It contains one or more files or drives that have been compressed with Zip compression to reduce storage space.
NOY files allow users to backup important files to protect them in case the files become corrupt or lost. The NOY file is the primary file type associated with NOY Backup Utility, which enables you to create and open NOY files.
