Gigabytes are cheaper than ever but they can also be the sort of thing where the more you have, the more you tend to consume, and it doesn’t take long for the terabytes to fly by if you spend a lot of time on your computer. Those of you running Windows on a compact SSD probably know what a chore it can be to maintain enough space on your drive between mobile backups, Windows Updates, PC games, media files, and so on.
Junk file cleaners make it easy to perform a system-wide file cleanup and may be useful for freeing up storage on low capacity SSDs where a few extra gigs can make or break the performance of your operating system. If you’ve never used a junk file remover before, you might be surprised by how much space can be reclaimed with even Windows’ own built-in Disk Cleaner.
Windows 10 has an automatic disk cleaning service that you can enable in Settings > System > Storage > “Turn on Storage sense.” The feature auto-scans for temporary files when you’re low on disk space along with removing local copies of OneDrive files and making them online-only after not being used for 30 days.
You can also save space on files and folders without deleting them by enabling Windows’ built-in compression option: Right-click an item, go to Properties, click the Advanced button and check the box next to “Compress contents to save disk space” — click Ok twice to confirm/exit. Compressed files and folders will have blue text. Side note: Compression is undesirable for any system file or files that will be accessed even sporadically. Only use for archiving purposes.
These are the most extreme methods for recouping disk space on a Windows installation. While not recommended prior to trying the previously listed options, many gigabytes can be salvaged by making some advanced system tweaks.
