I use Portable Gaim and I'd find the logging feature useful, except that every conversation takes up 4KB (my drive's minimum cluster size). After a few dozen conversations (a new one is started just by closing and re-opening the window) I quickly get up in the megabytes.
Is there something that could remedy this? Thanks.
You could always get a bigger drive
Check out: Tools - Preferences - Logging
That's really your only easy solution. The 4KB size is simply a symptom of the file systems we have. It would be nice it Gaim could append to an existing log. Maybe per screen name. But that feature doesn't currently exist.
Sometimes, the impossible can become possible, if you're awesome!
