HELP!!! I cannot find the program I copied my hard disk with

Hi,
Last month I copied an Image of my laptop as it was messy and I needed to format it to my external hard disk. I used a program that I found on google but I can't remember the name, I know it was a 15 day trial. The only thing I have now is a 50.7 GB file, "laptopbackup.arc".
I've been searching on google now for ".arc disk image" but I can't find anything. What should I do??
Thanks to everybody for the help!!

googling backup arc gives me this link... Not sure if this is what you used, but maybe....??

Also, try googling .arc extension

I found a lot of useful links showing file types that use that particular extension.

no, this one doesn't have a trial, my program had a trial...
i already tried googling arc extension but the programs i found have nothing to do with disk imaging, i tried opening it with 7zip and winrar but they say it's not an archive

Stuffit isn't an imaging program, but it does have a free trial and should be able to decompress the .arc file

i tried but it didn't work, it's just another compression program, the program i used was to copy disk images, is there any way i can analyze the file to see something about it? if i could just see inside it i saved the program on the desktop of the image, i would know the name.
Please if you know any way I'm desperate I have information inside that I have to access this week!

Is it possible that it was Acronis? http://www.acronis.com/ It has a 15 day trial.

There is also Paragon which has a 30 day trial http://www.paragon-software.com/home/hd ... nload.html

From what I was reading they both use a .arc extension for their image archives.

I was thinking Acronis as well.

i tried acronis true image home, and it saves in .tib, it doesn't recognize my archive... what should I do? I've googled for hours and I asked in about 10 forums.
Isn't there a way to just open it like when you open a small file in notepad just to know what it is? any type of analisys to see what's inside, what code it's written in?

Maybe you can convert it to something else??

it said it doesn't recognize the file because it's empty, but 50 GB is NOT empty!

The point is that it's a proprietary format, there has to be a way to recover the data to find out what program i used, I can't be skrewed like this with 50 gigs of useless data, it's not even encrypted, if there is no way to parse it in raw then they might as well stop encrypting and use programs like this one!

I have no idea what else you can try. Without knowing what program you used it is very difficult as the backup is in a format I am not familiar with. Curious why you just didn't use the native backup that is included in Windows.

What about this

Sound familiar.
