I like to load all save game files that are in the save game folder without knowing the names of the files. Is this possible in blueprint?
What I would like to do is let players make save their own levels with the level name being also the save game file so levels can then be shared freely. I also like to add Steam Workshop additionally at some point but I guess there I will get the same problem.
Use FPaths::GameSavedDir() to know what directory to search in. use IPlatformFile::FDirectoryVisitor to load all the files in the directory and look for .sav files.
