If you have an OLM file larger than 5GB containing hundreds of emails, and you want to extract only the attachments (without converting the entire mailbox), then the most suitable and easy solution for you is the Softaken OLM Attachment Extractor Tool. I have used this tool myself and it processes large OLM files without hanging. It is specially designed for users who need to extract only attachments from an OLM file and not the entire mailbox conversion.

Key features that make it special:

Handles large OLM files with ease.

Extracts only attachments, without disturbing the email body or structure.

Can extract attachments from hundreds of emails at once with batch processing
support.

Saves attachments in a neat folder, making them easy to find and manage.

Its free trial version is available, in which you can see its performance by extracting some attachments.

In case of any problem, 24x7 support from its team is also available.
