Strange file type on my external hard drive

I've got a folder with all my avi files in on an external hard drive but a strange file has appeared in it.

The file extension is .bd and is named with all strange characters, it is 4gb in size but if i try to delete it it tells me to insert disc into my dvd drive.

anyone know what this is and how i can get rid of it?

it might be a backup file, your hard drive is automatically making backups of certain files.
I am probably wrong

It seems it is something to do with a solaris browser data file, have a look here, they are part of sun micro systems who design java technology

What program uses .BD file extension?

Seems odd? especially the size, 4gb is far to large to be java i would have thought, initially thought it could be backup data (bd), is it a mac?

Just out of interest have you scanned the file with your anti virus software?, also do you use bitdefender, also if you have a scroll down this site it lists all known programs that associate with .bd, see if there are any that you use,

tried scanning it with antivirus and nothing happens :? i don't use bitdefender or any of the programmes listed.

It's a bit of a strange one

Im stumped?? have had a good search & tried loads of resources to search for alternative to the .bd extension 99% come back as not found??

Must be a system file or something for the hard drive then!

yeah but it's only just appeared and i've had thei drive for months.

the actual file is this: f:3!®»õT.bd

followed by two files like this: f:f: and f:ï0£¿C which have no file extension

If you right click on the file & choose properties what information does it give you with regards to the file, under opens with & the created on date?

opens with Windows Shell Common Dll and it doesn't say when it was created

The shell files are files that are used to run the operating system? i wouldnt try and delete it at the moment incase for some reason it has migrated itself or copied itself from the windows folder, going to have to dig about a bit and come back to you tomorow if you havent sorted it out by then
