Hi,

I found a bug in Delta chat 1.28.3 on Android

in the directory /data/data/chat.delta/cache/image\_manager\_disk\_cache  
there is a lot of files with a random name .0  
these are PNG pictures for a letter of the contact.

thousands of files are here from older messages and are never deleted.  
Could you deleted them ?

in the same directory there is a file named “journal” with numbers of olders messages and this JOURNAL is never purge from old data.  
Could you delete the old data like ?

DIRTY ad9d48b3b6842e5dc628e[…]2224310375f6eda541b498c80  
CLEAN ad9d48b3b6842e5dc628e[…]24310375f6eda541b498c80 8697  
READ ad9d48b3b6842e5dc628e[…]23375f6eda541b498c80

in the directory  
/data/data/chat.delta/files/accounts/74523[…]bf52/dc.db

there is a table named “msgs\_mdns” with old msg\_id, contact\_id and timestamp\_sent  
about old deleted messages.  
this table is never purged.

could you purge the old data ?
