How to increase disk space on your PC by getting rid of useless files, large programs and adding a new drive

Disk space If it is true that new internal memories are increasingly larger, it is also true that the photos and videos stored in them have become so numerous that, in the long run, they can become problematic for disk space.

Furthermore, many portable PCs have small-capacity memories (the average is around 500 GB) which require freeing up space frequently compared to desktop PCs (where 1 TB or 2 TB memories are also found).

If our PC falls into this type of problem (internal memory always full or not very large), let’s see together all ways to increase disk space to prevent general performance from slowing down and to be able to save new files, photos and videos without having to delete anything or almost nothing.

Disk Cleanup built into Windows

Without installing any type of program, you can use a tool built into Windows to delete temporary files and other data as well as update installation files.

To use the tool Disk Cleanup just open File Explorer in the Start menu, click on the section in the sidebar This PCright-click on the disk containing Windows (usually C:) and press up Property; a new window will open in the tab Generalin which we have to press the button Cleaning disk present in the section Capacity (immediately below the pie chart with the remaining space).

From the window that opens, select the types of files you want to delete: temporary files, log files, files in the recycle bin, and other unimportant files, then press OK. Before proceeding, however, we can also include system files in the cleaning; by clicking below Cleaning system files in the window Cleaning disk you can delete those Windows Update installation files. In this regard, we have noted how they can delete files over 4 GB only from Windows Update and other unused Windows files.

From the system file cleanup window you can also press the tab at the top More options to delete all restore points (except the last one created for safety), so as to recover this space too.

In Windows 10 and Windows 11, the same file cleaner tool you can start it by going in Settings > System > Storageby pressing up Temporary files.

You can also activate the function from here Memory sensor which automatically deletes excess files when necessary.

2) Remove the heaviest programs

From the Windows uninstaller, which we can find on any version of Windows in the Control Panel -> Uninstall a programwe sort the programs by the space occupied by clicking on the column Dimensions and we remove the ones that are heavier and are not used.

For example, Java can be removed as well Adobe Acrobat Reader which can be replaced with a smaller alternative program.

If you are using Windows 10 or Windows 11, you can remove larger programs from it PC Settings in the section System -> Apps & Features. From here you can remove both Windows Store applications and regular programs.

3) Check the occupied space

To find out what is using disk space on your PC and easily find the largest files you can use a program to see how your PC’s disk space is used.

Among those listed we recommend using WinDirStat which, after scanning the system, will show us a list of all folders and files sorted by space used.

Just click on larger folders indicated by the program and discover, through the path tree, which files or folders take up the most space on our hard disk. Obviously, you shouldn’t delete Windows system files or even program files to avoid running into problems! Let’s limit ourselves to deleting useless personal files or uninstalling the programs that generate the largest files.

4) Clean temporary files

While the tool Disk Cleanup of Windows is useful for recovering wasted space from files that are no longer important, however it does not delete temporary files used by other programs.

For example, it cannot delete temporary files created by Firefox or Chrome, whose data caches can take up several Gigabytes of disk space. We can clean temporary files and obsolete files download free CCleanerthe most popular computer cleaning program.

By regularly running this program we will be able to deeply clean our PC from all temporary files and useless files generated by programs installed on Windows, as well as speed up the PC thanks to the auto-start program control tools.

5) Add or replace internal memory

The best way to increase disk space on a computer it is, without a doubt, that of add a new drive to that which may be present.

The best SSDs to use for desktop PCs and laptops are:

  • Maxtor Z1 SSD yes 240 GB (20€)
  • Silicon Power SSD 256GB (23€)
  • Kingston A400 SSD Solid State Drive 480GB (€33)
  • WD Blue SA510 500GB 2.5″
  • Crucial BX500 1TB

If instead we are looking for a modern M.2 NVMe we can view one of the models below:

  • Crucial P3 500GB M.2 PCIe Gen3 NVMe (36€)
  • Lexar NQ790 1 TB PCIe 4.0 SSD Interno, M.2 (69€)
  • WD Blue SN570 1TB M.2 PCIe (64€)
  • Samsung 980 PRO M.2 NVMe SSD (92€)
  • WD_BLACK SN850X 2TB M.2 (163€)

6) Other methods to increase disk space

If we want to get even more space we can use the function compression of drives, files and folders as explained in the article accompanying the link. Alternatively we can use the function Compact OS in Windows to recover disk space.

If the space problem concerns particularly large personal files, the use of services Cloud like Google Drive or OneDrive, it allows you to save large files and keep them always available from any PC, without taking up space on our physical disk.


Disk space is never enough, especially if we download a lot from the web and we use files that tend to immediately take up a lot of space (just think of video recordings, ISO images or images for virtual machines).

The advice is to immediately choose a PC or laptop with at least 1 TB of internal memory; if this space is not enough we can always follow one of the tips set out above to solve all the space problems that can arise on a PC that is a few years old.
