Windows 7 File Association Remove

In windows 7 the file associated with the respective application has been changed. In previous Windows XP file association was simple. Where as this feature doesn't include in Windows 7.

Thanks to ExtMan is a free program for Windows users who want to create, edit or delete file extensions in the operating system. It adds the functionality to Vista and Windows 7, but runs fine under Windows XP as well. With little bit of complication as the program's language is in German and there is a option to select to English, but in confirmation windows pop it is still in German.

ExtMan is an ultimate solution for me to add or remove file extension in Windows 7

If you are using Zimbra Mail and you are not able to send any mails and also you see an Error Message " not enough free space in mail queue " under /var/log/message. Then you should try out this solution. 1. Login to the server, and then again login as zimbra as follows: #su - zimbra 2. Check the Postfix message_size_limit, by default it should be 10MB (i.e. '10240000' bytes) as follows: $postconf message_size_limit message_size_limit = 10240000 3.
