• Blazing fast speed – Take advantage of our high speed servers;  your uploads and downloads will be lightning fast!
• Reliability – We have servers all over the globe, and all file uploads are hosted on the cloud. Making sure that our upload infrastructure is always available to handle your uploads.
• Simplicity – Don’t want to worry about setting up and managing upload/download servers? Don’t want to worry about the HUGE costs associated with the bandwidth and disk space necessitated in uploading and storing large files? Use our infrastructure! After all, it’s free… Let us foot the costs and the headache for you.
• Integration speed – By utilizing our file upload infrastructure you can literally add a couple of lines of code to your website and immediately be uploading and sharing large files. Your customers, clients and friends will be able to send you an unlimited amount of files up to 2GB each and it’s all free!

How to use Sizable Send infrastructure to send and share large files:

1. Create a standard POST file upload script.
   • You do this by creating a standard HTML form and adding an input attribute of “file”. You can do this in any programming language. An example is provided later in this article.
2. Point the “Action” of the HTML form to our servers:
   • If the file is between 0MB and 480MB in size make the “Action” of the form point to “http://www.sizablesend.com/scripts/upload.php”.
   • If the file is between 481MB and 2000MB in size make the “Action” of the form point to “http://largefiles.sizablesend.com/scripts/upload.php”.
3. Make sure that your upload form has the required form attributes listed as “required” in Table 1A below.
4. That’s it!!!

Table 1A – File uploader attributes:

Sample file upload form:

<form id="uploader" name="uploader" method="post" action="http://www.sizablesend.com/scripts/upload.php">
<input name="sess_id" id="sess_id" type="hidden" value="{You need to generate this dynamically at http://api.sizablesend.com/v1/GenerateSessionID/}" />
<input name="U" id="U" type="hidden" value="Remote" />
<input name="SenderEmail" id="SenderEmail" type="text" />
<input name="RecipientEmail" id="RecipientEmail" type="text" />
<input name="Files" id="Files" type="file" />
<input name="Submit" type="submit" value="Submit" />
</form>

Sample file upload script return:

By default the upload script will return two values, a short link and a standard link, both will link to the file download page. Below is an example of what is returned after a file is successfully uploaded:

http://twelio.com/oodwm3<||<>||>https://www.sizablesend.com/file/wiyjrp/nevis.ttf<||<>||>

You’ll notice that the links are separated by the characters “<||<>||>” – this is done to differentiate between the two returned values. They are included solely to help differentiate between multiple returned values. You’ll also notice that the download links are returned in a certain order. They will always be returned in the following format: Short download link<||<>||>Regular download link<||<>||>Additional values, such as Twitter and Facebook sharing links, an example of this is below:

http://twelio.com/kxyuig<||<>||>https://www.sizablesend.com/file/p34nrd/nevis.ttf<||<>||><tr><td><div id="posttotwitter">Post to Twitter:</div></td><td><a onclick="_gaq.push(['_trackEvent', 'File Syndicated', 'Twitter Syndication Click']);" target="_blank" href="http://www.addthis.com/bookmark.php?v=250&winname=addthis&pub=streamlinedfusion&lng=en-US&s=twitter&url=https://www.sizablesend.com/file/p34nrd/nevis.ttf&title=SizableSend.com Free File Download - Filename: nevis.ttf (0.01 MB)">Click here</a></td></tr><tr><td><div id="posttofacebook">Post to Facebook:</div></td><td><a onclick='_gaq.push(['_trackEvent', 'File Syndicated', 'Facebook Syndication Click']);" target="_blank" href="http://www.addthis.com/bookmark.php?v=250&winname=addthis&pub=streamlinedfusion&lng=en-US&s=facebook&url=https://www.sizablesend.com/file/p34nrd/nevis.ttf&title=SizableSend.com Free File Download - Filename: nevis.ttf (0.01 MB)">Click here</a></td></tr><tr><td><div id="posttostumbleupon">Post to Stumble Upon:</div></td><td><a onclick='_gaq.push(['_trackEvent', 'File Syndicated', 'Stumble Upon Syndication Click']);" target="_blank" href="http://www.addthis.com/bookmark.php?v=250&winname=addthis&pub=streamlinedfusion&lng=en-US&s=stumbleupon&url=https://www.sizablesend.com/file/p34nrd/nevis.ttf&title=SizableSend.com Free File Download - Filename: nevis.ttf (0.01 MB)">Click here</a></td></tr>

You’ll notice that the social sharing links are formatted in HTML table tags, this is done only to help with presentation, you can ignore these HTML tags.

To use our custom file uploader on your website simply copy and paste the following code into your webpage source code:

<iframe src="http://embed.sizablesend.com/iframe/v1/" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:700px; height:500px;" allowTransparency="true"></iframe>

This code will embed our unformatted file upload module. What do we mean by “Unformatted”? Basically the file uploader is bare bones with no fancy CSS stylings.

If you want to customize your file uploader with a custom CSS style sheet you will want to change the code to look something like this:

<iframe src="http://embed.sizablesend.com/iframe/v1/?CustomCSS=http://www.MyDomain.com/CustomUploaderStyle.css" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:700px; height:500px;" allowTransparency="true"></iframe>

With the CustomCSS query string parameter you can specify any stylesheet you want; do note however that this custom stylesheet will override ALL other styles of the file uploader. This allows you to fully customize the look and feel of the embedded file uploader.

You can also specify the Sender Email Address and/or the Recipient Email Address – thus not allowing the end user to choose. If the querystring parameters SenderEmail and/or RecipientEmail are specified, their corresponding input boxes will NOT appear, example:

<iframe src="http://embed.sizablesend.com/iframe/v1/?CustomCSS=http://www.MyDomain.com/CustomUploaderStyle.css&RecipientEmail=customer.relations@sfusion.com&SenderEmail=customer.relations@sfusion.com" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:700px; height:500px;" allowTransparency="true"></iframe>

Below is a summary of the query string parameters you can customize:

Continue reading for a more detailed explanation of the “I/O Error”:

WHAT is an “I/O Error” error?

• An I/O Error, commonly referred to as an “In/Out Error” is an error that occurs when there is a problem writing(the “In” part of the error) or reading(the “Out” part of the error). Writing happens as we save the uploaded file data to our servers and Reading happens as we continually and progressively read the uploaded file data on our servers comparing it against the saved file on your computer; essentially making sure the version on our servers matches the version on your computer.
• It can transpire when you are uploading files to our servers and a “glitch” with the file upload process occurs. Continue reading for what we consider a “glitch”.

WHY does an “I/O Error” occur?

• The error (“glitch”) will occur when the file upload process is inturupped.  (see below for a analogy; highlighted in a yellow box)
• The following are possible reasons a file upload could become interrupted:
  • Your internet connections goes out – This is the most common reason an I/O Error occurs; it is also the hardest issue to troubleshoot since often when your internet connections goes out you will never know it because it only goes out for a split second. When the “connection is dropped” even if for a split second, this is enough to corrupt the file upload and will require you to start the large file upload over. Luckily this, while the most common reason for the “I/O Error”, is itself something that doesn’t often occur.
  • Your web browser stops responding – This usually happens in Windows, especially on old or spyware/virus infected computers. When a browser stops responding, even for a split second, it will cause the file upload to fail.
  • Your computer freezes – Again, even if this happens for a brief moment it will cause the file upload to fail.
  • Your file is corrupted – A file that has a virus, is infected with spyware/ad-ware or is corrupted in general will cause an I/O Error. Sizable Send will not accept corrupted files of any type as a safety measure for our end users downloading the files.
  • You have too many “packet errors” – Every file, small or large, is split into millions/billions of “data packets” when it’s uploaded to our high speed file download servers. Although our system is designed to cope with multiple packet errors during file upload, too many errors will cause the upload to fail. Some reasons for packet errors occurring are:
    • High network congestion – basically if you have tons of people/devices on a network and are everyone is doing a lot at once, packet errors can occur.
    • Old routers or networking equipment – Think of routers/switches/networking equipment as the traffic director on a very busy 4-way traffic interection. If that intersection is very very busy and that traffic director can’t cope with the load there are bound to be accidents. Older networking equipment often can’t cope with high load or “traffic” and this can cause packet errors or “accidents” to occur.

Why does an “I/O Error” usually occur with larger files?

• Uploading large files simply takes longer than uploading small files and therefore there is a higher probability of an I/O Error occurring.

HOW can I avoid/stop an “I/O Error”?

• Remember, the I/O Error rarely occurs to in the first place, so 99.999% of the time simply trying to upload the file again is all that needs be done. If that doesn’t work try the following one at a time in order:
  1. Restart your web browser and try uploading the file again.
  2. Restart your computer and try uploading the file again
  3. Restart your router/modem/networking equipment and try the file upload again. NOTE: if you have multiple devices, unplug them all then plug them back in in the following order: Your modem, router, switches, anything else. Make sure to let each item fully boot up before you power up the next device. If you dont know whether a device is fully booted up or not, just wait 2 minutes for each device before mo.

Post a comment below if none of these suggestions fix the issue and we will contact you directly to help you further.

By default the file upload notifications come from DoNotReply@SizableSend.com, however if you would rather emails come from something like YourEmail@YourCompanyName.com that can be arranged depending on the custom file upoader package you select.

To do this we will need your SMTP server connection details and account credentials.

What SMTP information do we need?

• A username, e.g. DoNotReply@SizableSend.com (the username is usually the email address)
• A password, e.g. 1234
• The SMTP server, e.g. SMTP.ServerName.com

Below is a list of some common errors that can occur during the uploading process:

The lists are split into two general categories based on the size of the file(s) you are uploading. Why? Because file size is directly related to the length of time it takes to upload a file. And the longer it takes to upload a file the greater chance (albeit very small) that an error will occur. However do note: You will NEVER be limited by us on the speed at which you can upload a file. We pay top dollar for the fastest bandwidth money can buy and the only thing that would be causing your file to upload/download slow is the speed of your internet connection.
