Q&A Rename Multiple Files 8.12.09

Wednesday, August 12th, 2009

QUESTION:
How do I change the file type of multiple files at once, in windows.
I have a bunch of tiffs that do not have the *.tif file extention. I need to add it. And it is going to be rather tedious if I do it one by one.

ANSWER:
Heard on #75 & #76 of Windows Weekly on TWIT the answer to this question

(Using Windows Explorer; No Additional Software required)
In Windows Explorer you can select a file and right click and click rename. (This you know). After you rename you can hit tab and it will move you to the next file and the text is already selected and you can edit it. (an you go on and on all day renaming files this way)

(Automated Program for Renaming)
The program is called Ant Renamer. (Was covered on Episode #76; Link is below and its mentioned and linked right off Paul’s podcast list below; Keyword the page for Ant Renamer if you want to verify.)

Question of the Day 8.5.09

Wednesday, August 5th, 2009

QUESTION:
Anyone know about a biometric identification system that can work for all? I read somewhere that Iris detection can’t properly identify certain individuals with eye disorders or who are blind?

ANSWER:
I haven’t researched this but as a rule any biometric security device is dependent on individuals having those parts to measure or scan for unique characteristics. If your disabled or in some way an can’t use that kind of device then I guess that’s an obvious downside but then again the nature of biometrics. I’d just implement a token system for those that couldn’t use a a biometric scanner (such as the one linked below) which is an OTP (One Time Token) system.

PS- A good biometric solution does not violate privacy in any way the unique characters that are scanned are turned into a quantifiable data or code that is run through a hash witch is non-reversible. And the hash is stored not any photo or any thing like that.

By the way I’m a disabled IT Security Professional.

Question of the Day 8.4.09

Tuesday, August 4th, 2009

QUESTION:
Anyone know what a shared secret is when using a VPN on Mac?

ANSWER:
Not entirely sure. I assume if its like a shared key on a Wifi router. In such a case a shared key or secret is a code or password that is used to generate the symmetric encryption key. The key or secret is shared offline generally although you could share it some other way.

Question of the Day 8.3.09

Monday, August 3rd, 2009

QUESTION:
What is the quickest way to move files from one hard disk to another – it tells me it will take 1078 hours to transfer 27GB – sounds wrong. (What to do?)

ANSWER:
If that’s the Microsoft copy tool built into windows then yes its probably wrong. I use TeraCopy for big copy routines especially since Windows is known for skipping files or hitting a road block and not telling you what caused the problem or where to resume. TeraCopy was recommended on the TWIT podcast network by Windows Weekly. Links below and I beleve you can find the file on CNET downloads as well.

With this said if your trying to copy a drive that you boot off as a whole that won’t work. Some of the files for Windows are active. You’d have to boot of something else like your second drive and start the copy routine from there.

Fastest Option: Drive imaging is the fastest option or drive cloning. This for what you stipulated would take 20-45 minutes. (Norton Ghost can image not sure about cloning)
