Will the uninstalling of apps leave file cruft in the root (Android's subsystem)? Will the uninstalling of apps leave files in the root (Android's subsystem)?

When we uninstall some program on Windows, it leaves some files along the system, does it happen on Android too? If this happens, would it be be wise to access the root to erase this files and free some space?
Not in the internal filesystem, but it may leave files on the SD card.

Apps on Android are only able to write on two places within the filesystem


/data/data/&lt;packagename&gt;
/mnt/sdcard/ or /sdcard


The /data/data/&lt;packagename&gt; directory gets deleted when you delete the app, so the only place where file cruft can be found is the SD card.
