If you want to have a check box that can filter container fields based on the type of file in side them, say for example
Choice1 = psd, jpg, png, bmp, tga
Choice2 = txt, doc, docx, xls, html, xml
Choice3 = mov, mp4, avi, wmv
Can you define Choice1, 2 and 3 each in a Case statement to put in a value list?
Are there any functions that are helpful in deducing what type of file is in your container file?
