You may be surprised to know that your Windows operating system and the applications that run on your computer generate temporary files.

This article is meant to help you understand what these temporary files are used for and how they may impact the performance of your computer and the capacity of your internal hard disk.

What are Temporary Files?

In the Windows operating system, temporary files are created both by the OS itself and many of the applications running on your computer.

Many of Windows’ temporary files are denoted with a file type of .tmp or are prefaced with a tilde (~). Most of the temporary files that are created end up in the Windows Temp folder.

They are used for a variety of reasons including:

Operating system requirements such as providing space for virtual memory.
Work files for applications that hold data while the program is running.
Files created as backups for works in progress such as Microsoft office creates for open documents.

Why Should I Remove Temporary Files?

There are two main reasons to clear out the temp files in Windows 11 or any version of Windows for that matter. They are:

💽 Regaining storage space – Temporary files can end up taking up a lot of storage space. Over time, they can accumulate and represent a significant percentage of your disk’s storage. Removing temporary files which are no longer needed gives you more space for the important data that you need to store.

💡Improving computer performance – Temporary files that are needed by Windows or other applications can negatively impact your computer’s performance as they grow larger.

Loading and searching these large files can slow down your computer and the applications that you are using. Eliminating these files can considerably speed up your machine’s performance.

Before you can delete the temporary files on your machine, you need to locate them. Here is how you can find the Temp folder in Windows 11 as well as earlier versions of the OS.

1. The first is located at c:/Windows/Temp and is used by the OS to store temporary files. Press Windows + R, type: temp and press Enter.

2. The second is the Temp file related to the user currently logged into the system. Here is how to find those temporary folders.

Windows 11/10 – Using the search field located to the right of the Start button, enter %temp%. The folder at the top of the results is the Temp folder.

Windows 8 – On the “Start” page click on the magnifying glass icon located in the top right of the window – next to your username. Type in %temp% and click on the folder named Temp.

Windows 7, Vista & XP – Click on the Start button and in the search field type: %temp% Click on the folder called Temp.

Steps to Delete Temporary Files in Windows:

You can follow this procedure on both the WindowsTemp folder as well as the folder returned from the searches listed above. The below process remains the same on any version of Windows. We’ve illustrated using Windows 10.

Recovering Accidentally Deleted Files and Folders on Windows 11

It is possible that in your quest to clean up the temporary files and folders on your system, some files may be accidentally deleted. In deleting temporary files and emptying the Recycle Bin, you may realize that you inadvertently removed a file or folder.

As soon as you discover that there are files you need to recover, stop using the computer. This gives you the best chance of recovering the files by limiting the possibility that the OS will overwrite the files before they can be restored.

Steps to recover deleted files & folders on Windows 11:

Download and install Disk Drill for Windows. We strongly recommend that you use a USB drive or another external storage device for this task. This removes the possibility that the download and install can overwrite the files you are interested in recovering.

Click Search for Lost Data. The advanced algorithm will scan the device for lost files, and a progress bar will indicate the progress.
Filter through the search results to select the items you wish to recover. Click on Recover.
Now, choose the recovery location. Ensure that you don’t use their original locations, as this can lead to corrupted files that are overwritten as they are recovered. Click on OK.

Disk Drill’s powerful scanning algorithms will interrogate your disk on a sector-by-sector basis and recover any files that can be salvaged. It is a great tool to have available in case you make a mistake when you are cleaning up your machine by deleting temporary files.
