Yesterday I downloaded headers of a couple of groups, such as alt.binaries.cores (about 2.75 billion posts) from two servers at once (giganews, easynews) and over 40 of such files as:
Storage.db3-mj0E27E49D7
Storage.db3-mjC94B8394B
....
still remain even when the background processing ended and the cache reached 0.
Even after I restarted NewsBin.
Even after I ran additionally "Download latest"
Do they indicate some corruption or I can just delete them?
Until now, I always downloaded headers from giganews only (at least V6 headers) and I see only one such file in all the headers of various groups I have.
In my experience those files disappear when the cache reaches 0.
But not in this case.
