Regardless of the file system you may have configured on your system, it is always a good practise to follow a valid naming convention for all files and folders that are created and used on your system. The points listed below will help you get accustomed with the most important rules when naming files or folders:
Unnecessary files such as, temporary Internet files, recycle bin files, applications temporary files, setup log files, offline web pages, thumbnails, downloaded install programs and system error reports take up disk space and have an impact on data access times! The Disk Cleanup tool removes these obsolete files.
Start the Disk Cleanup tool by typing disk cleanup in the Start search text box.
Although startup times are the result of many variables that differ from one computer to another, the following steps will help you optimize this time. Most commercial applications perform similar actions, therefore, it is wiser to have some knowledge about the startup process and perform the changes yourself, as you are in the best position to decide what is essential or not required in your system. Remember, that third party applications are generic and can do unwanted changes!
External USB hubs that have their own power supplies do not consume power from the computer and most often are called self-powered devices. On the other hand, the computer’s internal USB hub is bus-powered, that is, it consumes the computer’s bus power. One needs to be aware of devices that require a lot of power such as, cameras and should take the necessary precautions to protect both the device and the computer’s motherboard.
From the Device Manager’s USB controllers node you can check the power allocations for a USB hub and find if too many devices are using that hub.
