I've noticed that although copying a file will also copy the descript.ion entry, renaming a file inside DOpus means the description gets lost because DOpus does not update the filename inside descript.ion. Perpahs this is something that could be fixed in a future version? Thanks.
Works OK here.
Note that descript.ion changes aren't written to disk immediately, but instead are delayed and written as a batch. (Better for performance is multiple descriptions change in a folder.) So if you're looking at the file itself, it may not have updated yet, but should after a minute or so. Using File > Exit Directory Opus and then restarting can be used to force any pending writes to disk when testing things.
That might explain it. Thank you.
