How to Fix - do i need these files or can I safely delete them??

do i need these files or can I safely delete them?

running windows 8.1 on a pc.
when I open my downloads folder I find a load of installation files that use up room on my puter:
flv_installer (3)
flv_installer (2)
flv_installer (1)
Chrome install-7u51
Chrome install-7u45(4)
Chrome install-7u45-(5)
Chrome install-7u45-(3)
Chrome install-7u45-(2)
chrome install-7u45=(1)
and several other INSTALL files.
I am an old guy and want to keep my computer cleaned up but don't want to screw it up.
If these files are for installation purposes, do I still need the after the installations?  Many thanks for your kind advice.

You can go ahead and delete them...............they were used to download/install your FLV Player and also Google Chrome.
(over and over).

and make your computer run more efficiently.
Windows Key + E
right-click on Local Disk (C:)
Select "Properties"
Select "Tools" (tab)
Select "Optimize" (it will check to see how much disc space you can free up), then....
Select "Defragment" (this will rearrange the files in an orderly fashion on the disk so that they
will execute quicker)
Click APPLY
Click OK

To check for Windows updates. Open Windows Update by clicking the Start button , clicking All Programs, and then clicking Windows Update. In the left pane, click Check for updates, and then wait while Windows looks for the latest updates for your computer. If any updates are found, click Install updates.
