Hi all,
I'm a long time reader, first time poster - but I discovered something this morning that I believe maybe useful for some...
My wife received an email from a trusted source with an attachment she had been expecting - namely, a poster design draft for her job.
The problem was, the sender sent the file without saving it correctly with an appropriate extension (.doc, .pdf etc) & when she downloaded it - attempting to open it in Word just brought up the hex converter. The same result in PDF Xchange etc.
She asked the sender to send it again only to receive the same result. In business, it is not uncommon to receive a file the other party can't open for whatever technical reason - but it can be embarrassing asking for it to be sent again & again to no avail.
So, she asked me to have a look at it. Normally I wouldn't advocate opening an unknown file type, but it it's come from a trusted source & they've confirmed that they've sent it - to save any embarrassment here's how to identify the type of file you have:
Firstly, to be on the safe side - upload the unknown file type to www.virustotal.com - if you get no hits then you're good to go.
Next, go to: http://ift.tt/rK7BOZ & download "TrIDnet File Identifier" which is the Zip file & underneath is the vital RAR file containing the file definitions to make it work.
Using something like 7zip or Winzip - extract the folder containing TrIDnet & extract the RAR definition file to the same directory. i.e. c:\tridnet\
Once you have the TrIDnet.exe file available, open it up & press the "Rescan Defs" button. There should be just shy of 6000 so it caters for most file types.
Click "Browse" to locate the file missing it's extension & then click "Analyze"
It will then analyse the code of the file and produce a file type underneath (.pdf .jpg .doc etc)
Go to the file missing it's extension in Explorer & add the file type identified by TrIDnet to the file name (filename.jpg). The icon will then change to the relevant type & you should be able to open it.
In my wife's case, the file was a .jpg - which never crossed my mind to try for a poster draft!!
Hope that's of use to someone...
