Mark: If you are talking about a user uploading a file to your website from their desktop - no - there is no way to do it that I am aware of. Anything on the client side would need access to the file system. Browsers are not allowed to do that. Maybe you could do it with Java if the program was signed and the user chose to trust it? If you are moving a file from one server or folder to another you can use the getFileInfo function to check the size before you move it. I will be happy to be wrong if someone knows better as I would love to be able to check a file size before upload. Cheers I found this online - was checking to make sure my knowledge wasn't outdated. :-) Sounds like it might have possibilities. About the Javascript...there *is* a trick I have used to check the file size of a file, but it requires the user to load it locally.
You basically create a new Image object with that file name the same way you do with image pre-loaders and check the size property of the Image object. I have used it to get file sizes of images and audio files, but it should work with other types as well. If I remember right, the Image object loading is asynchronous, so you might need to define an onload function that will be called when the file is actually loaded.
