Is there an actual upload file size limit?

I've placed the Pure ASP Upload 3 on a page and get an error dialog after selecting a file to upload - a video file of 144 Megabytes - saying the file size exceeds the maximum file size of 102400 Kbytes (or 102.4 megabytes). There is no explicit filesize limit in the properties. Is this the limit of the file size I can upload or is this a bug??

Hello Peter,

The extension does not limit the file size all of the limits are handled by your server.

Hi Theodor: Thanks for you reply: Actually, I am able to upload files up to 1 Gigabyte in size using other upload controls. I only get the error message from the DMX Zone Pure ASP Upload 3 control, so it would appear that there's no problem with the server accepting large files. Are there any setting in the ASP Class that might be at issue?

Can you please provide a link to a test page where we can check this?

Teodor: You were getting the same error message when you tried the Pure ASP Upload 3 on your server. You told me you were "referring the issue to the deverloper" and that it would be resolved in about 1 week and that you'd contact me via email. Have not heard anything further from you on this. Can you tell me if there's any new developments on this issue?

Hello Peter,

It was the server setting that was limiting my upload.
The problem was discussed with our developers and there is no a limit set in any of our upload extensions.

I have to say that your reply does not seem to make sense because: As my original post states, the error dialog, which comes from the extension, pops up as soon as the file to be uploaded is selected on the local machine - to repeat, as soon as the file to be uploaded is selected on the local machine - the upload has not even been initiated. If it's the server that's limiting the upload then does the extension do a query on the IIS settings before an upload? I don't think so. In addition, I can upload in excess of a 2 Gigabyte file using ASPUpload from Persits (www.persits.com) to the very same server where the ASP Pure Upload 3 is with absolutely no problem.

This is quite strange.
Please try setting a large limit in your Pure Upload Settings and check if the error message appears again.

Teodor: Regarding this issue with the upload file size: As I mentioned in my previous and original comments on this, I was getting a error screen coming from the extension, not the server, when ever I selected a file that exceeded 102400 Kbytes even though in the control there was no limit specified: I you look at the code in the above comments you will see that there is no filesize limit indicated, so according to the documentation, there should not be an upload limit - however I was getting the error when ever I selected a file that exceeded 102400 Kbytes (or 100 megabytes) even before the upload was started. Your last response to me was to try a set a filesize in the control, which I did. Apparantly, there is a bug in the Pure ASP Upload 3 extension because when the maximum file size is blank, a) the warning, before the upload even begins, that the 102400 Kbytes file size error is coming from the extension, 2) with the version of the control I have, leaving the maximum upload file size blank as the documentation states, does NOT result in a allowing a file greater than 102400 Kbytes to be selected without getting the error msg. Lastly, you stated that there is no upper limit for the file size. That is really not the case because: assuming for a moment that the server where the Pure ASP Upload 3 is being used with (IIS6 - IIS7) accepts any file size in an ASP upload, the extension used the CLng (Long integer type) in the incPU3Class.asp file: the variable in that file is m_MaxFileSize, and it appears on line 134 of that file. You will note that the maximum file size is limited to CLng(lngsize/1024). For a Long integer the maximum file size is 2,147,483,647 (per Microsoft's VB Reference) which is slightly larger than 2 Gigabytes. So, for the the PURE ASP Upload 3 the upload limit - assuming the server being used has not limits set - is 2,147,483,647 bytes or 2.147483647 Gigabytes. So that's the limit for the PURE ASP Upload 3 file size, at least for the version I have. The documentation needs to be corrected to indicate that a value needs to be included or the extension may indicate a false error in terms of the upload limit.
