File Upload and File Size Limitations

[Robert Strickland]

What is the default file size limit when uploading a file and can the
administrator up that limited when needed?

You can add or modify the following section in your web.config file:

<configuration>
<system.web>
<httpRuntime maxRequestLength="4096" />
</system.web>
</configuration>

The above value (4096 KB) is the default maximum upload file size.

You can add or modify the following section in your web.config file:

<configuration>
<system.web>
<httpRuntime maxRequestLength="4096" />
</system.web>
</configuration>

The above value (4096 KB) is the default maximum upload file size.

It's also important to note that the current implementation buffers the
entire uploaded file in memory, which means it's not suitable for uploading
large files.

Cheers,

Is there any code or suggested method of uploading large files? We may have
to upload files over a gig is length?

There are 3rd party utilities you can buy that can break up the file into
chunks and upload a piece at a time.
They also can provide you with the "impossible to display normally" -
progress bar.

There was long thread posted a year or more ago that described how to solve
this problem yourself.
The issue is the posters only provided 80% of the code and then "went
private" and sold the rights to these utility companies. If you are
competent enough then you could write your own but...

There are some good 3rd party tools out there that help with uploading very
large files.
Here are a couple:

You'll also need to set larger the timeout value in order to upload very
large files.
(It can take a few hours to upload gigabytes of files for broadband users,
let alone the 56k dialup users.)
