In my project folder system the file shows correctly as "1602 | Based on 05 | 161124.11.pln" but the name of the file on-screen resulting from the Save As action is: 1602 | Based on 05 | 161124.11.pln [Read-only].
Why has the [Read-only] been appended and what is the effect of the file being designated that way?
I know this is an old thread but I have this too, only Archicad 25, it is a pain, it seems to still save but I always save to desktop then back into the correct folder just incase
