Can 'coredump' folder be deleted safely? Internal memory (1.21 GB) of my phone is mainly occupied by a folder named 'coredump' (size ~900 MB). Will it be safe to delete it? What should i do to release this memory?
Short answer
I wouldn't recommend deleting the folder itself, but it should be pretty safe to delete its content (i.e. the files inside). I'm just afraid you won't be able to do so – unless you have root access on your device.
Explanation
Core dumps (on some Android devices also called &quot;tombstones&quot;, which somehow explains their purpose) are generated when an app crashes (or force-closes). They usually contain a complete dump of the memory that app was using, plus some additional information – and are intended for debugging purposes (to provide the developer with information about the state the app was in when it crashed – hence &quot;tombstones&quot;, describing the &quot;dead of a process&quot;).
The system itself doesn't need them at all, so deleting them should be pretty safe. However, depending on implementation, the system might rely on the fact the folder is there – so removing the folder along might have &quot;negative side-effects&quot; (should not, but who knows). As an empty folder is not using up any space, it shouldn't hurt to keep it.
On the other hand: as its only purpose is collecting those &quot;crash reports&quot;, and as they probably won't go anywhere either: who cares whether &quot;writing those crash-logs crashes&quot;? ;)
