CMS Made Simple Forums

I have been learning how to set CMS up for a client to update his site. But today I have a specific question regarding this client uploading a large slideshow zip file into CMSMS. I am still doing his updates, I only want him to upload from his computer now and I will do the rest. Is this possible?

I'm not sure what you mean; he should be able to upload files using the File Manager, if he has permission.
