Cache files

Cache files are the different files that are stored by our device which is used to boost specific function in future.
Take an example of a website you visit a few days back on your device which will save some cache files regarding that site in the browser itself which will be used if you visit that site again to load it faster.
Similarly every app you use stores some cache file to work efficiently.
Such cache files are not that much important that is why you should clean them every month.

Obsolete files

Some apps in our smartphone create obsolete data to work efficiently.
These files are temporary and can be deleted easily.


Some files we install on the device and after installing the leftover file is called packages.
Deleting those files doesn’t affect anything on the installed device.


Residues are files, folders that are created by some apps that have no work after that app is uninstalled leftover files of that native app are called residue files.
Deleting such files doesn’t affect anything so delete them.


Memory is nothing but cache the main difference is they are not attached with the app they are stored in a different location in storage.

    That's why hardly you will observe any obsolete file while cleaning trash files.
