Deleting Rendering files during a project

Hi guys,

Can someone please help?

I see a lot of support notes regarding deleting rendered files AFTER a project to free up space, but what I want to know is if one can safely delete render files DURING a project as well.

I am currently working on a major film project, whose length will be a bit over 90 mins of heavy footage comprising special effects, audio effects, transitions, images etc As you can imagine, it is voraciously eating up my hard drive.

Well, being a big project I expected my hard disk space to be depleted, what I didn't anticipate was the volume of space the Rendered files would eat up.

I am currently still working on the project, and I am only 30 mins into the project and the render files have already generated 3-digit Gigabytes, and growing.

On smaller projects, I would normally just delete the render files and move on, but on this major film project I am a bit too wary of the consequences of deleting render files in a bid to free up space.

A lot of forums suggest that it is ok to delete render files, but most are often stated within the context of a completed project. I want to know if the seemingly safe action of deleting render files applies to both ongoing and completed projects. Before hitting the delete button, I want to be sure there won't be dire consequences for my ongoing film project?
