Unnecessary files take up a lot of memory.
Junk Files (“junk files” or “unnecessary files”) occur whenever you use your computer. As the name suggests, this is digital junk – data that can be safely disposed of.
So that you can work efficiently, the computer saves not only your current activity but also the latest changes to files. For example, if you are using a text creation and editing program such as Word, you can easily recover the last typed passages. These temporary files are important for usability.
Usually, unnecessary temporary files are deleted themselves. For example, once you close the program in which you were working, you will no longer access the previous operations. Ideally, these temporary files end up in so-called Temp folders. However, often this digital junk remains on your computer, taking up the memory of your device.
Programs such as CCleaner safely remove such unnecessary files. However, always pay attention to what you delete because not all tools can tell junk from essential files.
What are junk files on a smartphone?
Unnecessary files can also be on your smartphone – you’ve probably seen a folder with this in the built-in memory cleaner on Android.
Typically, these are temporary program files and data stored in the cache. The fact is that applications frequently save different information on the smartphone not to download it again: avatars on social networks, the latest audio and chat messages, uploaded videos, banners, etc. All this ends up in the cache and can take up a lot of memory. For example, they ate about 4 GB on the editor’s phone.
You can also delete unnecessary files on smartphones – but it’s better to do this using the built-in Memory app or additional cleaning tools rather than manually. If you start cleaning file folders yourself, there is a risk of deleting important data that the applications need to run.
