I think that he’s referring to setting the page file or swap file in Windows. This controls the amount of disk space that Windows uses for virtual memory. See here for an easy explanation, https://www.askdavetaylor.com/how_can_i_fix_too_little_virtual_memory_in_windows.html , or search for page file in this forum and you should find plenty of opinions on the subject. I hope that this helps.
Thanks for the link. I was there the other day and I swear there wasn’t a Media Manager link. Sony must have just added it. Either that or I’m dumber than I look and that would be quite a stretch!
