If you already have all the headers, why should it download the same headers over again?
Because of incomplete files or if I deleted some posts by accident (with shift-del).
Maybe other have other reasons.
But I think, the question should be, why not allow to download the same headers over again with "Download Special".
If it can't make problems, then user as me (or other) don't think it's a bug, when it doesn't work as supposed
You could program to do the "Post Storage/Use Download Age" for the group first when someone is using the "Download Special" function.
No more user are asking then why the Download Special function doesn't work
What version are you using?
Using 6.71RC1 now, but the last time I had the incomplete files problem was with 6.71b4.
If you want to re-download over your existing headers without deleting all the old ones first, right click the group "Post Storage/Use Download Age" then set a download age that goes back in time as far as you want. Then download headers normally. This will do what you thought "Download Special" was supposed to do.
Instead of setting the download age in the settings dialog, I will use the "Download Special". It's faster and I don't have to change the download age back to the normal high value.
In your case, in you server advanced options, you might want to set a larger overlap. Maybe 1000 headers.
I wrote that.
(But thanks for mentioning
)
Well I will look for the incomplete files problem the next header updates.
All the best,
