Twitter DM Deleter is an easy to use tool for batch deleting direct messages from a Twitter account.
Manually deleting these messages one by one at twitter is burdensome, especially if it is too large. If you are an active twitter user and have lots of useless messages, this tool is certainly useful.
With Twitter DM Deleter you can see all direct messages (required Twitter login), then select few or all and delete them with a click of a button.
Note: If I select too many messages for deleting, I found that the utility is crashing (in Windows XP), otherwise no problem. The developer should look into that.
