How to email large files?

Email attachments can be a hassle, especially when they’re large


This can be the most frustrating part of any email-based communication. Unless you have a special number of recipients or are savvy enough to use encryption; it’s not always possible to send an email that includes a large file.

If you have a large file attached, there are two ways to fix this:

1) Save the attachment as an image (and then save it in a folder);

2) Use a conversion tool to compress the size of the file before sending it.


When sending a large file, there are a few things to keep in mind


If you are sending a large file; one that is larger than a couple MB; it can be tricky if you don’t know what you’re doing or you’ve never done it before. If the recipient has a large file server set up; there are ways to send big files through the mail system without actually copying them over. It’s important to note that this isn’t an easy process, and it takes time and possibly multiple attempts to get it right.

The first thing to keep in mind when sending a large file is the size of your file. There is no standard for what is considered “large file size”; so take care to understand what your target audience will use your file for before making assumptions about its size and trying to transfer it over.

If you’re trying to send an image, keep in mind that much of the time people may just want to crop the image or put it on an album in their photo library, yet they expect their email attachments to be big enough for printing out a nice-sized picture.

Large folders or archives are great examples of this

If you have one or more of these; try sending them as attachments instead of emailing them separately along with other documents.

If your file is too big for email, or if your recipient has no idea how large an attachment can be before they delete it, consider using some sort of online converter tool (like Dropbox). These tools will do most of the work for you while saving you from making any mistakes (or waiting forever). If those fail, remember that even if someone does delete all those attachments from their email program after receiving them, they won’t notice; and all you have lost is their time and energy.


There are a few ways to send large files, but some are better than others


Whether it’s sending a large file over the Internet through something like a Dial-Up connection; or simply sending a large file over the Internet; there are some things to know about what you can do and what you should not do.

The good news is that there are different ways of doing this. The bad news is that some of them work better than others. The solution to most problems lies in figuring out which one works best for your project and your situation.

Sometimes, all you need to do is send the file as an attachment rather than through email or FTP (or whatever method you use). This means you can put the file anywhere on your computer, including on a USB drive. You can also compress it in any of dozens of compression programs on any PC you own (or in anything that can compress photos).

Another thing I wrote about recently was how I was able to send an entire ISO image without having to open it up and read it first (even though Mail doesn’t understand file names from Windows PE images). It took me almost no time at all — but at least I now know that this is one case where I can have my cake and eat it too!


Consider using a cloud storage service to send large files


A few months back I was working on a file transfer project with a coworker. I thought it would be fun to share the file with him; but after a while, it hit me: we were storing the file in one place, and he was just storing it in another. I decided to use Google Drive instead of Dropbox to store the file. That way we could both communicate with each other via email with the files stored locally in Google Drive.

That meant that our end-to-end security didn’t get compromised; no malicious actors could download our private files on either device!

This may sound silly to someone not used to storing sensitive information online. But if you’re already making use of cloud storage services; you may not have considered its implications for your end-to-end security.

I mention this because there are many other ways you can get exposed to potential privacy risks when storing large amounts of information over the internet (e.g., using a public Wi-Fi network). As such, you should think about how your data is being stored before deciding whether or not you want it online (and then consider whether or not you want your data stored online).


Sometimes, it’s just easier to bring the files in person


When it comes to sending large files over the Internet, there are both good and bad cases. On the one hand, it’s possible to send a file over the Internet without any special tools. In fact, you can even do it with your own computer (albeit with a lot of extra work). But on the other hand, you can never get 100% security from an unreliable or insecure service.

The big risk here is that if your company offers something that is not only free but also fast (and therefore potentially very popular); it will be vulnerable to a Sybil attack; a group of people using the same account to send different files at the same time. In this case, it is possible for anyone to create fake files and send them as legitimate files to your employees or customers.

A good way of protecting yourself from this threat is by having enough security on your servers so that no one can use them for any other purpose than what they were created for (i.e., sending messages / attachments). This means installing some kind of firewall; or at least limiting the number of services that are allowed on port 10080 (or some similar port in your firewall) to only those applications that actually need access to those ports for their own purposes.

It goes without saying that if you want your company’s website(s) accessible outside its offices; you should also install FTP servers or proxies/firewalls in front of them as well.
