Forums Feature Suggestions $folder identifier

If by folder size you mean the total size of its contents then just loop through its contents with $findfile() & $file().size and add it up yourself - that's effectively what mIRC would have to do behind the scenes anyway.

It's perhaps best not implemented as a built-in identifier as it can be slow to calculate if the directory contains many (ie. thousands) of files. Generally speaking people assume mIRC's built-in identifiers will return a value near-instantaneously.
