View limit in Download folder

When creating a game on Battle.net, I can view all maps in Download folder. However, in single player -> play custom -> Downloads, I can only view the first ~250 maps. How can I view all maps or delete maps in my Downloads folder so I can play a custom map in single player?

If you go into documents through file explorer (on windows of course dunno of mac) you’ll see a folder for Starcraft, open this then open Maps. Here you can create new folders to rearrange and organize them. (simply cut/paste them to put them in new folders or delete them)
