Windows Mobile .MPB files taking up space

I have a Samsung i760 windows mobile smartphone. I have had it since the beginning of July. Switching from my Palm Treo 700P was a great upgrade. Having real email and being able to receive my .wma attachments and play them has been a huge benefit since my voicemail system sends the message as an audio file attachment.

But I've noticed the phone slowly getting slower and slower and more unstable over time. My storage memory space had been reduced down to just over ten megabytes and I could not find any other way to clear this out. However, I just installed MemMaid and found that the windows/messaging folder had over 40mb of files ending with the .mpb file extension. After some research online, there was not a lot of information but I deduced that these files were left over email that were not deleted when the message was removed. I backed up my outlook files on my pc and then connected the phone w/ activesync. Once connected, I went into file manager and deleted the over 300 .mpb files and now I have over 50mb of space in the Storage Memory. It's quite liberating actually, being able to reclaim this space that was just being wasted for no good reason. One thing is for sure, MS just does not comprehend the concept of lean and mean. MS is definitely the king of bloat. I have not yet done much with MemMaid, but it seems like a great tool and I will probably end up registering it considering that it helped me find over 40mb of crap wasting space on the phone.

Anyway, I wanted to share this in hopes that it may help someone else experiencing the same windows mobile storage memory issues.
