Windows will normally hide some important files from general view by default, with the intention to prevent misuse or accidental deletion of these files by you, the user.

Some files, however, are very critical to the use of your software, and while it's important not to delete them or alter them in any way, your technical support staff may need them at any given time to review and/or troubleshoot any particular situation you may be experiencing with your software.

Here is a quick screen shot of where you'll find the setting to make those files visible, so you can find them more easily if and when needed.

From the Windows Control Panel, access your Folder Options menu, then match the settings of the picture below, and finally click Apply and Ok.
