When you use several apps on your laptop, some files and cache are created in the background that you are probably unaware of. Ideally, you should delete these files immediately after completing a task, but if you don't do so for a long time, they accumulate clutter and slow down the system's performance. The two methods for deleting temporary files in Window 11 are listed below.
- Delete temporary files using File Explorer
To delete the temporary files follow the steps mentioned below.
To launch the "run" command press "Windows + R". Enter "%temp%" in the run text field and press "OK".
Press "Ctrl+A" to select all files. Select the "Delete" icon.
It might ask for Administrator access. Press "Continue" to proceed with the process. It will delete all the temporary files from your system.
- Delete temporary files using command prompt
To delete temporary files from the command prompt using below are follow the steps explained below:
To launch the search menu press "Windows + S". Enter "windows terminal" in the search menu. Right-click and select "Run as administrator".
A command prompt will appear. Type the following command and press Enter.
del /q/f/s %TEMP%\*
It will delete all the temporary files from the system.
Windows has an option of saving all your deleted items in the Recycle Bin so that you can recover your items whenever required. Windows keep these saved in the recycle bin for 30 days.
Another method to free up your C drive space is by emptying the Recycle Bin timely. If you have never emptied your Recycle Bin, it might be taking up a particular area in your C drive, causing it to get packed.
The following simple steps that you can follow to empty the space in your Recycle Bin:
- Manually emptying the Recycle Bin
You can manually empty your Recycle Bin by opening it from the desktop. Select the Recycle Bin icon on the desktop. Click on "empty Recycle Bin".
It will ask you to delete files permanently. Select "Yes" all files will be deleted from your system.
Note: Before you start emptying your Recycle Bin, make sure that no important files you may need later. If there are any, revert them to their original location before emptying the Recycle Bin.
If your C drive is full and slowing the progress of your PC, try to transfer the large files to an external drive so that you can free up some space on your drive. Adding a new hard disk or shifting your files to an external hard drive will improve the performance of your computer.
If your whole system is out of space, your C drive is small and cannot contain all your files. You can consider upgrading the current hard drive to a new one with more capacity.
The "Disk copy" feature of the EaseUS Partition Master has the potential to help you upgrade to a larger disk without reinstalling the operating system or application. You can upgrade the hard drive by selecting the source disk you want to copy. Then you choose your destination. Now edit the target disk partition size; when the program warns it will wipe out all the data on the target disk, now click on "continue".
You can either choose:
- Autofill the disk
- Edit disk layout
- Clone as the source
These options will help you customize your disk layout as per your choice. Once done, proceed to start your disk cloning process.
We have discussed all the effective steps that can be taken to help your C drive work effectively without slowing your processor.
To avoid any unnecessary data loss, it is always important to backup your data to another drive. To enjoy a seamless experience without having a fear of losing your data and improving your C drive disk space, you can use the EaseUS Partition Master. This tool is professional and one of the best to choose to extend your C drive.
