Viewing All Files in Temporary Downloads

Though the downloads temporary files will not show all in one folder, you can still safely delete temporary files manually. Below are the steps to delete temporary files the standard way.

• Type %temp% on Cortana and press Enter key to open the
  Temp folder containing temporary files.
• Select the folders or files you want to delete, then click the Delete
  key to delete all temporary files.

It is recommended that you move temporary files to Recycle Bin and permanently delete them after few days. This is for you to have the option to restore files if a program or Windows does not work properly after the deletion.

Regards.

 

Deleting Temporary Files

Yes, they can, and should be, deleted periodically.

The temp folder provides workspace for programs. Programs can create temporary files there for their own temporary use. Each program should delete all its temporary files when it closes, but for various reasons it doesn't always happen (for example,
if the program crashes, it never gets to do this). That's why it's a good idea to periodically clean out anything left there.

Also note that there are some program installations which work in two steps. The first step concludes by writing temporary files and rebooting. The second step starts automatically after rebooting and needs to find those files there (and then deletes
them when it's done).

Other than doing it automatically when rebooting (that would interfere with installations like the kind I described), it's always safe to delete the contents of the temp folder. Because it's safe to delete any temp files that aren't open and in use
by an application, and since Windows won't let you delete open files, it's safe to (try to) delete them at any time. If any fail to delete because they're open, they'll either be deleted automatically when the app using them closes, or you'll get them the
next time you delete manually.

Some people may suggest that you reboot before deleting anything, but that's not necessary, for the reason described above (on the other hand, it doesn't hurt to do it).
