Check File Size Before Uploading

[bweno]

Is there anyway to check a files size before uploading it to the web server. I have searched the web over and found nothing for coldfusion...

Thanks in advance!!!

CF doesn't have any ability to check for the size of your file before it's
stored on the server. The best you can do is check immediately after it is
uploaded, and delete if it exceeds a certain size limit.

Once the file has been uploaded to the CF server, you can reference it's file
size with this:

cffile.filesize

Then you can insert logic based on the results.

Ex. <cfif cffile.filesize GT 40960>Error message here<cfelse>File
Accepted</cfif>

Hope this helps.

You cannot do it only in ColdFusion (or only in PHP or ASP). You can use a
Java applet to upload the file and check the file size before uploading.

You might want to post that link on the other thread, for the people that inquired.

Check out the var #CGI.content_length# for a general idea on the size before you decide to receive the file.
