No, as Karin put it, purge and compress are two different things.
It's just in TB you can't do Purging without compression. The "Purge
all folders" command under the Folder menu does do compression,
which should be renamed to "Purge AND COMPRESS all folders". The one
for a single folder ("Purge and Compress") is clear.
The Compress and Compress All Folders commands, OTOH, don't purge.

I went back to look at the explanation Karin gave you, and found what caused the confusion. I'm also at fault, of course, since I endorsed what she said without thinking. I guess she was lacking caffeine, and I simply had a bad day though it was only morning. Now, Karin's explanation is still a good place to start: KS When you delete a message from a folder, it is not really KS removed: it is only taken out of the folder's index file KS (*.tbi). This is almost right, except the index entry isn't really "taken out". It's marked as deleted. That's why you can "browse deleted messages", which would be much harder to do if the index entries no longer exist. KS When you purge, it is really deleted. Here, "purge" should be "compress". (In dBase/Clipper terminology, it's "pack".) What does "purging" do, then? It means deleting old messages according to a set criteria. If you have experience with higher-end newsreader, you should have no trouble with this concept. In TB, the criteria is set on a folder-by-folder basis (try Folder | Properties). If you set a folder to keep no a maximum of 100 messages, e.g., then when you purge it TB would delete all messages but the newest 100. When purging, TB delete them in its usual way--marking them as deleted in the index file (.tbi), but not removing them physically from the message base file (.tbb). Yet, as I said earlier, purging in TB is always followed by compression (either on all folder or a single one). The reverse isn't true. Hope that is clear enough. -- Best regards, Ming-Li The Bat! 1.52 Beta/4 | Win2k SP1 -- __ Archives : http://tbudl.thebat.dutaint.com Moderators : mailto:[EMAIL PROTECTED] TBTech List: mailto:[EMAIL PROTECTED] Unsubscribe: mailto:[EMAIL PROTECTED] You are subscribed as : archive@jab.org
