That works but /run is not going to wait for it to be done, mIRC will keep processing your code, just like with timer, being able to know when it's done might be just super useful.
Ok true... So providing you are deleting the folder just to gain back the ability to write/read from it without clashing with the previous data you just deleted and are not wanting to know when its done to display some sort of progress. Couldnt you rename the directory before hand, and then use that command to delete? That way you can create a new directory with the old name as soon as the rename is done.
Probably a bit hacky but depending on what they are trying to do, it should work.
