5. Since e107 2.3.0 version list of files to be deleted can be checked from /e107_system/{{RAND_FOLDER_NAME}}/logs/fileinspector/deprecatedFiles.log. Since post upgrade the script does not ask to delete any folders, we have commented the code to delete folders in upgrade.php. Check this in every version.
