Extra files when unistalling app

[Members_T1TR8S5]

Hello I have a problem when I uninstall an app e.g. minecraft it asks do you want to keep the files I decided yes and when I reinstalled it it says package conflicted with a source or whatever now that normally happens when you already have an app installed but it's uninstalled and I think it's because of the extra files do you know where I could find the files and delete it. It also shows that when I install it it says update? Please let me know what I should do

When I uninstall an app I also go into the Playstore and MyLibrary to delete the app there too under the Manage section. 

Use the optimisation tool found in your Device Care and if necessary try Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

There is your MyFiles app too. 

If i can be of any further help please don't hesitate to ask  😎
