Changes in Bucket Explorer Amazon S3 - 2007.12

Bucket Logging for audit

Bucket logging helps user to keep track of all the activities and events performed in the Bucket such as upload/download/delete activities and provide an audit trial to track these operations. A user needs logging since all the activities in Bucket affect billing. It is used when a user creates bucket and imparts full permission to all Internet users / outsiders. He/She can keep track of the entire activities through logging. Analysis of the traffic on his/her bucket, and estimation of his/her data transfer will also be possible through logging. A user can control his/her billing on the basis of data transfer analysis.

Customized the bucket location as Europe or US

A user can create a Bucket in Europe or US using Bucket Explorer. Create Bucket option shows the user both locations where you can select any of those.

Bucket Sharing

Bucket Explorer allows user to share object(s) and Bucket(s) with an Amazon S3 registered user using Email ID or owner ID in ACL Preferences box. It adds a new row in ACL Preferences box for User Name and a the user can give desired permission for that E-mail ID. A user can also share and access Bucket with an un-registered user by providing ACL permissions like Read only, Write only etc.

"Hide/Unhide bucket" option

It allows user to hide the entire un-required buckets from the main bucket space holder and reduce the time to be taken to search the required bucket. A user can also unhide the entire hidden bucket whenever he/she needs it. It prevents gathering of unnecessary buckets and objects that may confuse the user wheneverhe/she selects his/her needed objects. Thus, user can retrieve his/her needed data more easily. It also secures data that can be altered by other users, if user uses this option for security purposes.

Upload files with custom headers

Bucket Explorer provides Upload with custom header in which a user has to specify Keys and value that will be displayed in Object properties . This information helps the receiver to understand the file details without opening it. In this Example: From:, here From is a key and is its value.

Upload files in HTML format for Web Hosting

Intimation for new Amazon S3 User

When a user runs Bucket Explorer the first time and there is no buckets in his/her account, it will prompt the user to create the first bucket on Amazon S3. Just after this prompt, a " create bucket " dialog box will appear. It is useful for a new user as a guide.

Generate public URLs for multiple objects

This option helps a user to generate URLs of selected S3 object(s) by showing a window that shows URLs for selected objects where you can select 'HTTP URL', 'HTTPS URL', 'Torrent URL', 'Signed URL'. User can set a particular Expiry date from the calendar and also set time in hours, second and minute for signed URL. Use Bucket Name as Virtual Host  is usedto select bucket name as a virtual host. The Copy  option copies the selected URLs and Copy All copies of all URLs.

Nick name option

In preferences option in tool menu, General Setting sets "Page Size" that enables you to show desired number of objects in listing at one time. It also automatically detect setting, checks option automatically and connects to the default machine by which your machine is connected.
