recognized extensions
INTERDUBS will detect the file type based on the file extenison it does finds:
quicktime: .mov .mp4 .m4v .m1v .m2v .mpv .mpg .mpeg
flash video: .flv
flash content .swf
windows media: .wmv .avi
images: .jpg .jpeg .png .gif .tif .tiff .tga
PDF: .pdf
other extensions
If INTERDUBS should not recognize the file extension then it will simply store and serve the file again.
When INTERDUBS can not generate an icon based on the content it will pick one representing the file type.
You can use 
add icon, found under
edit file to add one if you like.
the browser / web server and other file types
When INTERDUBS does not recognize the file as an image or movie then it will just link to the file directly. In the case of pdf files for instance this does work in all cases. Other files have varying success. In order for a link to work the web server and web browser need to know what to do with the file in question. If it should be the web server that gets in the way, then please let us know: We are happy to change this.
ways to always get your file
Under no circumstances would INTERDUBS alter the content of the files that you upload.
You can upload anything. The client 
download function will give you back those files in all cases.
