Step one: Click the Chrome menu (the three horizontal lines in the top-right corner). In the pull-down menu select More tools > Clear browsing data, which will open a pop-up tab. (Or conversely, you can just press Ctrl-Shift-Del.)
Step two: In the new dialog box, check the box next to "Cached images and files," as well as any other types of data you would like to delete. In the pull-down menu at the top, you can control the time period over which you would like to delete data—everywhere from "the past hour" to "the beginning of time."
Step three: Click the "Clear browsing data" at the bottom of the dialog box.
This process is very similar to clearing data in Chrome—you can just press Ctrl-Shift-Del to open the Clear Recent History dialog box. Then check the box next to "Cache," choose a time range from the pull-down menu at the top, and click Clear Now." However, if that process doesn't clear your issues, then you can try this slightly more in-depth route:
Step one: Open the Options dialog box. You can get here two ways: 1) Hit the "Alt" button to reveal the pulldown menus at the top and click Tools > Options, or 2) Click the three horizontal lines in the top-right and then select Options.
Step two: Select "Advanced" in the top-right of the window.
Step three: Select the "Network" tab.
Step four: In the "Offline Web Content and User Data" and "Cached Web Content" sections, click the "Clear Now" button. And then hit Okay.
Are you still using IE!? You really should stop that. Even Microsoft is getting ready to dump it. And its history-pruning operation is dumb. It's simple, but unnecessary convoluted—just like Explorer. But here's what you do:
Step one: Open the Delete Browsing History box by 1) clicking Ctrl-Shift-Del or 2) clicking the gear in the top-right corner > Safety > Delete browsing history.
Step two: Be sure the box next to "Preserve Favorites website data" is unchecked. Conversely, make sure the box next to "Temporary Internet files and website files" is checked. Then click "delete" at the bottom.
This one is for Mac users only. For some reason, the most updated version of Safari doesn't have an easy direct route to delete your cache. You can delete your cache along with all your other browsing data (history, cookies, etc) by going to the Safari menu > "Clear History and Website Data" to prompt a pop-up similar to the other methods (except with the ability to delete different types of browsing data).
However, there is a way to delete just your cache if you are willing to take a few extra steps:
Step one: Enable to the secret "Develop" menu by going to Safari > Preferences > Advanced [tab] > click the "Show Develop menu in the menu bar" box at the bottom. This will enable the new Develop pull-down menu at the top of your browser window, which houses a bunch of under-the-hood goodies you probably won't ever need.
Step two: Click on the Develop menu and scroll down to "Empty Caches" (or alternatively, press Option-Apple key-E after the Develop menu has been enabled.)
