.TN File Extension

Tracor Northern Image File

Image File
The Tracor Northern image file is a special proprietary format which is not suitable for normal image processing and must be converted to a different format entirely in order to be used by most systems. Programs which use the TN image format generally convert it to a separate and also proprietary IMG format which can be used on MAC and PC computers.

The TN format consists of 512 rows each consisting of 512 pixels and each pixel consists of 8 bits of grayscale color data.

I viewed a .TN file extension on a micro SD card that was being used for camera storage in a Verizon cell phone. Each image was stored as a separate <filename>.TN file.

I did not have a means to read the file directly. It was forwarded from the Verizon phone as a .jpg file.

I am going to say the .tn file is created by the viewer in my Verizon env touch to view it faster, also the files are where as the actual jpg file is just in x:my_pix. (found this out trying to sort pics by alpha and the d*** phone won't let me, even if I delete the .tn files via sd card in my computer the phone puts them back after you put the sd card in the phone and view pics. on your phone).

Thanks for the response. I will do some more experimentation when I have time taking your comments into account. We're both "talking" Verizon phones so the .TN may be proprietary to Verizon. If you turn up more info please pass it along TNX, Clif

I am having the same exact problem, now I cant view my pictures on my phone because of this .TN extension.

Anyone know what to do? verizon told me to try converting the pictures extensions to a default extension.

So....since its on my Verizon env phone too, I'm thinking TN stands for thumbnail for the thumbnail pic in the preview?

So are the .tn files (cache files) just duplicates of the other pic files on the phone?

I have the same problem with a Verizon LG phone. Talked to Verizon technical support but it looks like it has to do with LG. I haven't been able to contact tech support at LG.

The Tracor Northern image file is a proprietary format which is just not suitable for normal image processing. It's used by several phones (not just Verizon). These .tn files are not duplicates of other pictures files on the phone!

Converting them into something useful is a hard thing on PC. It's a crazy hard thing on MAC.

I got my pictures! You must connect your phone with a USB to your computer and set your phone to USB Mass Storage.

There isn't any software required. Your computer needs to recognize your phone as an external storage device. There is a setting in your phone that you set it to (mass storage or data storage). Then your computer will automatically recognize it and you should be able to drag and drop your pics (or in my case "select"). After weeks of searching for ".tn" extensions, this works perfectly. It saved onto my computer as a .jpg! (I found hints for this for my LG phone online on the LG website.)

It might be easier to turn on both phones and send the photos via bluetooth. This worked for me.
