I include the file name on a design proof for reference, placed as variable text including the full file path. This string can be very long and yet it will not wrap in the text box; instead, it will only compress in width even to the point of illegibility. Is it possible to get this string to wrap ('soft returns') in the text box?
Unfortunateyl , no. A variable is a single character, according to the composer, so it can't wrap.
There are workarounds for running heads and such, but for the filename, I think you're out of luck.
