plesk consuming lot of space in server

[balechaparka]

I am using plesk panel. In my server i have plesk installed in C:\Program Files (x86)\Parallels folder and has size 1.59 GB.I think i cant delete any of files from this folder. I also have another folder C:\634933f54c6feef408dc523b402dbd37\parallels
which has 1.15 GB of size.now i wanted to know whether this is temporary folder and can i delete this.(also it should not cause any problem to my server and website in future).
C:\634933f54c6feef408dc523b402dbd37\parallels folder contains following folders:
BILLING-WIN_10.4.4
BILLING-WIN_11.0.9
PANEL-WIN_10.4.4
PANEL-WIN_11.0.9
SITEBUILDER-WIN_10.4.4
SITEBUILDER-WIN_11.0.8 and some other small files.
So i want to know can i delete these files? If so which files can i delete?
Thank u in advance..

It is installation temp folder where all downloaded files are stored. You can safely remove this folder.

Thank u for your reply.But i want to clarify which folders i can delete?
Is it C:\634933f54c6feef408dc523b402dbd37\parallels or BILLING-WIN_10.4.4,BILLING-WIN_11.0.9,PANEL-WIN_10.4.4,PANEL-WIN_11.0.9, SITEBUILDER-WIN_10.4.4, SITEBUILDER-WIN_11.0.8.
Becoz C:\634933f54c6feef408dc523b402dbd37\parallels also has some other files like parallels_installer_3.13.0.exe, microupdates.xml etc.So can i delete these exe file also?
what are these sitebuilder and panel_win folders?
