Bulk Copy Paste Files to Multiple Folders

If you want to copy a file or files to multiple folders and don't want to do it one at a time, you have several options.  You can use a third-party app for copying.  You can write a script (batch file, PowerShell).  Or if you don't want to have to resort to the extra work of obtaining an app or writing a script, try this: Highlight all the files you want to copy, then copy (select Copy via right click or by pressing ctrl+c).  Then select all the folders you want to copy them to by holding down ctrl while clicking with your mouse. Next, right-click on one of the folders and paste (either by right-clicking and selecting Paste or doing ctrl+p).
