These files, which include logs, caches, and downloaded installers, can be huge—this can hog precious hard drive space and even decrease the efficiency of your PC. This wikiHow article teaches you how to use tools built in to Windows to remove unnecessary files from your hard drive.

-
Select the files you want to delete.

The amount of space you'll save by deleting the selected files appears below the list of file types, and will update as you select and deselect files.
- Downloaded Program Files are the program installers you've downloaded from the internet. These are usually not needed after you've installed the file, unless you plan to install it again.
- Temporary Internet Files are the cached files from browsing with Internet Explorer.

- Device driver packages, Language Resource Files , and Temporary Windows installation files are all meant to be temporary and can be deleted without issue.

Open your Windows Storage settings. Windows keeps track of the types of files consuming space on your hard drive and makes it simple to delete the ones you no longer need. The Windows Storage tool makes it easy to find personal files and apps that you no longer need. To open your Storage settings:
- Press Windows key + S to activate the search bar.
- Type storage into the search bar.
- Click Storage settings in the search results.
-
Find the files consuming the most space on your hard drive. Once your storage settings load, you'll see the name of your hard drive (e.g., "Windows C:") followed by a list of categories (e.g., "Apps & features," "Music"). Each category is a type of file, and each has its own bar indicator telling you how much space is being used by that file type.
- To view all categories, click Show more categories below the list.
-
Click a category to view its details. This shows you how much space is occupied by files in this category, and gives you options depending on the type of files you chose.
- For example, if you selected Temporary files , you'll see a list of all files meant to be temporary on your computer.
- If you choose Music , Pictures , or Desktop , you'll see how much space is consumed by the files in those specific folders. You can click the View button inside to see the actual files.
- If you choose Apps & features , you'll see a list of all apps installed on your computer, and how much space each app consumes.
-
Delete files you no longer need. Be super careful here—just because Windows determines that a file or folder is large, that doesn't mean it isn't important to you or someone else who uses the computer. Only delete files that you are sure you no longer need.
- To delete an app from Apps & features , click the name of the app, and then select Uninstall .
- To delete a file or folder, click it once to select it, and then press the delete key on your keyboard. You can also drag it over to the Recycle Bin.
- Temporary files lists the types of temporary files Windows can delete and allows you to select from a list. After making your selection(s), click Remove files at the top to delete those types of files.

- Be careful you do not delete any critical files or your own documents. If you follow the guide carefully you shouldn't, but it is always a good idea to check the 'Recycle Bin' before emptying it, just in case!Thanks
