It will make impossible for TDLib to manage these files as part of application cache. They will never be deleted by optimizeStorage and will not be returned by getStorageStatistics. It...

Do you expect that TDLib will clean user's gallery if it is specified in `additionalScanFolders`? It's too dangerous to delete any file outside TDLib's file directory, because the file may...

Creating a hardlink or copying the file after it was downloaded is a good idea for now. Currently, there is no way to ask TDLib to create a file outside...

The error is likely to be in your code. You need to recheck everything again. If this will not help, you can send log with verbosity level 4 to @tdlib_bot.
