Deleting Rendered Files to save space

[johnf11772014]

This should be a very basic question -

After completing a project - is there any downside to going into the folder on windows and deleting all the files entitled "Rendered - nnnnnetc" both the media files and the xmp files?  I realize that if for some reason I want to go back later to work on the project I would have to render it all again - but I am looking for a way to clean disk space and I would not mind rendering again if that is the only difference.  I just do not want to destroy anything.

MIght want to do it the other way around: get a larger disk to create space.

A disk that in neary full always leads to trouble.

I have plenty of space on my computer for current projects - but  have many projects I have done over the last few years and - I am just trying to save old projects onto an external hard drive and it is filling up (and it is a 2TB drive).  So I am asking the downside of eliminating "Rendered- nnnnnetc." files from these old projects.  And/or are there other files that I could delete to save space.

You can delete any temp files but as soon as you open the project they will be created again.

Thanks - I understand now that temp files can be deleted - but is there a list of which files are temp and ones that are not?  Or which directories can be deleted?  I am using Windows 10.

Your temp files are set in the Preferences/Media cache.
