As operating systems and software applications improve, they become more and more demanding on disk space. Even if the capacity of the internal hard drives increases steadily, it may happen that the internal hard drive of the computer saturates and has need of free up space.
Several methods exist under Windows 10 Which make it possible to free up hard disk space: Discover the best of them.
Free up disk space in Windows 10 using Storage Assistant
We access thestorage assistant via [Start / Settings / System / Storage]. We can then have a view of all the hard disk partitions and how the space is occupied (see Example of storage wizard below).

To use thestorage assistant, you must activate it, then configure it so that it frees up space automatically. This will allow your computer to regularly clean the system and applications of unnecessary files. For this, the storage assistant acts on three parameters (see the Windows 10 storage assistant settings screen below):
- temporary files not used by applications
- the files contained in the recycle bin (with configurable delay)
- the downloaded files found in the [Downloads] folder (with configurable delay). For this last option, I recommend manually choosing the downloaded files to delete and leaving the option set to [Never]

Free up disk space in Windows 10 using Disk Cleanup
We access the disc cleaning by clicking [Start] and then typing [Disk Cleanup].
When starting Disk Cleanup, you must first select the hard disk partition to clean [C: /], [D: /], [E: /], [F: /] etc.
After a short time of analyzing the partition, we obtain a list of the different types of files that can be deleted, with an estimate of the possible free space.
Select the options of your choice to free up space on your hard drive (see the options in the screenshot below).

The Disk Cleaner also allows, using a separate option to clean system files ([Clean system files] button). This operation allows, after a short scan lasting a few minutes, to obtain a list of the system files that can be deleted (see the system files clean-up screen below).

Each of the options presented is accompanied by a short description allowing you to assess the relevance or not of its deletion.
