Message: Cant read file header.Unknown file format/file not found

I have downloaded a number of photographs onto the computer but when trying to open them, I keep getting the above message. Fortunately this doesn't apply to all the photos! I have tried using different software to open them i.e. Photoshop and Irfanview but still no luck. One photograph shows some picture and then the bottom half of the photo is just a block of grey? Can anyone help?

First check to see what the settings are set on how the files are saved. If they are set to RAW mode you won't be able to open them. Set the camera to jpg mode. Then you will be able to open them. The RAW mode is an advanced mode that requires an advanced operator to utilize all of the fuctions.

When I download a game or other thing it will come up and read cant open files

If these downloads are downloaded in a ".rar" ending file, you need to first extract that folder onto your computer. If the actual game itself is an ".iso" file, you need to google how to open ISO files. It's very simple, just very hard to explain when others do such a better job in less amount of time. =)

When i download song onto my mp3 it says unknown format what is up with this getting pretty angry let me know whats happening

Most likely something is wrong with the file. If it plays fine on your computer, you should use some kind of file conversion software (these can be found for free via google) or try loading the song into a video editor (windows movie maker) and saving it as an audio file.

I have four floor plan files made with Turbocad V6. When I try to run them to get a print I am greeted with the message "Failed to open;? Loading Header." I am running Windows XP Pro SRP3. Other files...

the issue is that you probably saved the files into a format that the computer u use now is unable to open and read ..the thing to do is make sure you have the program they were saved in ...and gave the print command from that program ..the one that the files was saved from
if you do not have them into this computer ..install it ...or see the file type on the properties...and look on the net for a reader for that type ...or let me know the format that they were saved look for a program that will read them ....also check to be sure they are saved correctly

What is a WMA/TrojanDownloader?

officially labelled WMA/TrojanDownloader.GetCodec

Win32/GetCodec.A is a type of malware that modifies media files. This Trojan converts all media files found on a computer to the WMA format and adds a field to the header that includes a URL pointing the user to a new codec, claiming that the codec has to be downloaded so that the media files can be read. WMA/TrojanDownloader.GetCodec.Gen is a downloader closely related to Wimad.N which facilitates infection by GetCodec variants like Win32/GetCodec.

This is a tough virus to remove so I suggest removing it early on. It can cause alot of damage to your media files.

Unable to open e-mail attachment

Open Files with .MSG File Extension Do you want to open a message with the Outlook .MSG file extension? The Encryptomatic MSG File Viewer makes it easy access Outlook MAPI message files (.msg files) created in Outlook 2000/XP/2003.
MSG Viewer reads .msg files encoded in western characters. It will display the text contents of the .msg file on your monitor. You can also print the message, save it to a text file, and extract file attachments.

Easy to Use Encryptomatic's Outlook .MSG Viewer is simple to use. It may be optionally installed as the default .msg file handler. This enables you to display a .msg file by simply double clicking it.
Extracts File Attachments from Outlook .MSG Message Files
Users can extract and save to disk any file attachments that were included in the Outlook .msg file, a useful feature not found in other viewers of this price class. To extract email attachments, just double click on the file attachment and save it to a directory.

viewer-screen.jpg What it Doesn't Do
The MSG Viewer is designed to give you quick access to an .msg file's text contents, file attachments and header information. It does not render colors, formatting or graphics, and it is not a full featured substitute for Outlook. With an RTF message with colored text and font formatting, the text will appear in black and white and the paragraph formatting will be lost (as in the message above). MSG Viewer displays only Western characters.
