您发送的那些文件对于电子邮件来说是否太大？也许您尝试了文本，但也没有用。幸运的是，有很多方法可以通过 Internet 向人们发送大文件，而且大多数甚至是免费的。
可能是您要发送给朋友的度假照片、您叔叔要求的家庭电影，或者您的音乐收藏、4K 原始视频文件、备份数据、视频游戏等。
无论您发送什么，都有办法让它发挥作用。但是，在选择发送大文件的最佳方式之前，首先要确定它们的实际大小，以便您使用最合适的服务（即，不要为可以获得的免费服务付费）。
计算整体尺寸
除非您了解文件的大小，否则您无法知道使用哪种文件发送服务。例如，如果您要向某人发送只有 800 MB 的电影，您可以使用与尝试发送 1 TB 视频集合不同的服务。
查看文件占用多少存储空间的最简单方法是将它们放入一个文件夹中，然后确定文件夹的大小。如果这就是您发送的全部内容，则可以对单个文件执行相同的操作。在Windows和Linux中，右键单击该项目并选择Properties；Mac用户应右键单击并选择Get Info。
选择文件共享服务
有很多(lots)
服务可以与其他人共享文件。一种选择是云存储，您的文件首先上传到与您的用户帐户绑定的远程服务器，然后您可以从那里与您想要的任何人共享这些文件。好处是您只需上传一次，然后就可以随时访问并轻松与尽可能多的人分享。
临时云存储类似于常规的在线存储，但文件不会保存很长时间，您通常不需要创建用户帐户即可使用它们。这些文件通常可以通过特殊链接与不同的人多次共享。
另一种选择是使用P2P文件共享服务，这样文件就不会保存在任何地方，而是直接从您的计算机传输到其他人的计算机。您可能更喜欢P2P服务，因为它们更具按需性，通常没有限制，而且您的文件不会保持在线。
缺点是，如果您决定再次共享文件，您将来必须重新上传文件，而且有人可以下载您的文件的速度受到您的上传连接的限制。
云储存(Cloud
Storage)
Google为任何拥有Google帐户的人提供 15 GB 的存储空间，您可以在Google Drive中使用其中一些与他人共享文件。在那里上传您的文件并与任何人共享整个文件夹或单个文件，他们可以以最大速度下载。您可以支付更多存储空间。
MEGA是一种云存储服务，主要关注加密和隐私。您将免费获得 50 GB，但可以升级以获得更多。文件和文件夹可以与任何人共享，并且您可以不共享解密密钥，这样只有知道链接的特定人员才能真正访问文件。
MediaFire允许您上传最大为 20 GB 的文件，您可以将这些文件与您的Basic、Pro或Business帐户一起使用，这些帐户分别带有 50 GB、1 TB 和 100 TB 的在线存储空间。
与他人共享文件和整个文件夹，即使他们不是MediaFire用户。付费计划提供高级链接共享，例如密码保护和一次性使用链接、文件夹下载、直接链接等。
临时云存储(Temporary
Cloud Storage)
Firefox Send允许您一次上传最多 2 GB 的数据（如果您登录，则为 2.5 GB），每次下载 1 到 100 次或五分钟、一小时、一天或一周后可能会过期。您还可以密码保护下载。
使用WeTransfer一次最多可以发送 2 GB 的文件，您可以通过电子邮件或特殊URL共享这些文件。一周后文件会自动删除，除非您获得WeTransfer Plus，它更像是一种永久云存储服务，您可以在其中存储多达 500 GB 的数据、密码保护文件共享等。
WeSendit.com的免费版本支持同时向多达 15 个收件人发送最大 5 GB 的大文件，每次上传最多可发送 500 个文件。通过电子邮件或链接发送下载；它们将在 7 天内到期。
支付(Pay)保费，传输限制跃升至 20 GB，并具有密码保护、100 GB 在线存储、无限存储时间等额外功能。
P2P 文件共享(P2P
File Sharing)
ShareDrop是一个空白页面，您和其他人可以在其中加入特殊链接并相互共享文件。根本没有文件大小限制或任何自定义。只需(Just)在虚拟房间中选择其他人发送文件，从您的计算机中选择文件，并让该人确认接受并开始P2P文件传输。
JustBeamIt免费文件传输网站可让您在互联网上移动文件，无论文件大小。(JustBeamIt)您将获得一个一次性链接，任何使用该链接的人都可以下载您准备的文件，但他们只有 10 分钟的时间开始下载或文件过期。
使用Takeafile 的(Takeafile’s)实时传输(Transfer)功能将最大 500 GB 的任何文件直接发送给其他人（无需服务器上传）。或者，使用云上传(Cloud Upload)选项作为临时云存储服务，以便收件人可以更快地下载您的文件；每个文件限制为 512 MB，并且不接受每种文件格式。
考虑压缩
无论您是通过电子邮件发送文件、将文件上传到云存储服务，还是通过P2P文件传输服务共享文件，压缩都会有很大帮助。
例如，如果您的电子邮件服务不接受一些文件，因为它们超出限制几兆字节，则将它们压缩到存档中可能有助于减少它们在传输过程中占用的整体大小。
如果您想一次共享多个文件，但您使用的文件传输服务只能接受单个文件上传，压缩也很方便。将所有文件放入存档中，然后上传该单个文件，然后收件人可以下载并解压缩以查看您共享的所有文件。
7-Zip是最流行的压缩程序之一，但其他一些选项包括WinZip、PeaZip以及操作系统内置的压缩功能。如果您不确定使用哪一种，您可以了解其中一些压缩工具之间的区别。(learn the differences between some of these compression tools)
文件传输示例
现在您已经很好地了解了如何确定您可能需要的传输服务以及在线发送大文件的选项，请按照以下ShareDrop示例查看它的实际效果：
第 1 步(Step 1)：打开 ShareDrop 网站(Open the ShareDrop website)。
第2步(Step 2)：按右上角的加号。
注意：如果您要将大文件传输给同一网络上的其他人（与您共享相同公共 IP 地址(public IP address)的人），请跳至第 5 步；ShareDrop 将自动识别其他本地用户。(Note: If you’re transferring the large files to other people on your same network — those that share the same public IP address as you —skip down to Step 5; ShareDrop will automatically identify other local users.)
第 3 步(Step 3)：复制您在文本框中看到的链接，并与您将文件发送给的人共享。
第 4 步(Step 4)：按知道了！在您的页面上。
此时，您应该会看到所有其他打开了您共享的链接的人。
第 5 步(Step 5)：选择您要将文件发送给的人的头像。每个人都在自己页面的底部进行自我识别。
第 6 步(Step 6)：从您的计算机中选择要发送的文件。
第 7 步(Step 7)：在
ShareDrop页面上按发送(Send)，然后指示收件人在其页面上按保存。(Save )
就是这样！现在，您可以查看收件人头像周围的蓝色进度条，查看完成P2P传输需要多长时间。文件传输完成时会短暂显示一个绿色复选标记。
How to Send Files Too Big for Email
Arе those files you’re sending too big for an
email? Maybe you tried text and that didn’t wоrk either. Fortunately, there are
lots of ways to send large files to people over the internet, and most are eνеn
free.
Maybe it’s vacation photos you want to send to a friend, home movies that your uncle asked for, or your music collection, 4K raw video files, backup data, video games, etc.
No matter what you’re sending, there are ways to make it work. However, before choosing the best way to send the large files, first identify how big they actually are so that you’re using the most appropriate service (i.e., don’t pay for what you can get free).
Calculate the
Overall Size
You can’t know which file sending service to
use unless you understand how large your files are. For example, if you’re
sending a movie to someone that’s just 800 MB, you can use a different service
than if you’re trying to deliver a 1 TB collection of videos.
The easiest way to see how much storage the
files are taking up is to put them into a folder and then identify the size of
the folder. The same can be done with individual files if that’s all you’re
sending. In Windows and Linux, right-click the item and choose Properties; Mac users should
right-click and select Get Info.
Choose a File
Sharing Service
There are lots
of services out there that can share files with other people. One option is
cloud storage, where your files are first uploaded to a remote server tied to
your user account, and then from there you can share those files with anyone
you want. The benefit is that you only have to upload it once, and then they’re
always accessible and easy to share with as many people as you like.
Temporary cloud storage is similar to regular
online storage but the files aren’t kept for long periods of time and you
usually don’t need to make a user account to use them. The files can often be
shared multiple times with different people through a special link.
Another option is to use a P2P file sharing service so that the files aren’t saved anywhere and instead transferred directly from your computer to the other person’s computer. You might prefer a P2P service because they’re more on-demand, generally have no limitations, and your files aren’t kept online.
The downfall is that you have to re-upload the files in the future if you decide to share them again, plus the speed at which someone can download your files is limited by your upload connection.
Cloud
Storage
Google provides anyone with a Google account 15 GB of storage, some of which you can use in Google Drive to share files with others. Upload your files there and share whole folders or individual files with anyone, which they can download at max speeds. You can pay for more storage.
MEGA is a cloud storage service with a primary focus on encryption and privacy. You’ll get 50 GB for free but can upgrade for more. Files and folders can be shared with anyone and you have the benefit of not sharing the decryption key so that only specific people with the link can actually access the files.
MediaFire lets you upload files as large as 20 GB which you can use with your Basic, Pro, or Business account that comes with online storage of 50 GB, 1 TB, and 100 TB, respectively.
Share files and entire folders with others, even if they’re not MediaFire users. Paid plans offer advanced link sharing like password protection and one-time use links, folder downloads, direct linking, and more.
Temporary
Cloud Storage
Firefox Send lets you upload up to 2 GB of data (or 2.5 GB if you log in) at a time that can expire after anywhere from one to 100 downloads, or after five minutes, one hour, one day, or one week. You can also password protect the download.
Use WeTransfer to send up to 2 GB of files at a time that you can share by email or a special URL. Files are deleted automatically after one week unless you get WeTransfer Plus, which is more of a permanent cloud storage service where you can store up to 500 GB of data, password protect file shares, and more.
The free version of WeSendit.com supports sending large files up to 5 GB to up to 15 recipients simultaneously, and maxes out at 500 files per upload. Send the downloads by email or a link; they expire in seven days.
Pay for premium and the transfer limit jumps to 20 GB with extra features like password protection, 100 GB of online storage, unlimited storage time, and more.
P2P
File Sharing
ShareDrop is a blank page where you and other people can join a special link and share files amongst each other. There are no file size limits or any customizations at all. Just choose someone else in the virtual room to send the file to, pick the file from your computer, and have the person confirm to accept and start the P2P file transfer.
The JustBeamIt free file transfer website lets you move files over the internet no matter their size. You’re given a one-use link which anyone who uses can download the files you’ve prepared, but they’ve only got 10 minutes to start the download or the files expire.
Use Takeafile’s Live Transfer feature to send any file up to 500 GB directly to the other person (no server upload). Or, use the Cloud Upload option as a temporary cloud storage service so that the recipient can download your files faster; it’s limited to 512 MB per file and doesn’t accept every file format.
Consider
Compression
Whether you’re sending files over email, uploading them to a cloud storage service, or sharing them over a P2P file transfer service, compression can help a lot.
For example, if your email service won’t accept a few files because they’re a few megabytes over the limit, compressing them in an archive might help by reducing the overall size they’ll take up during transmission.
Compression is also handy if you have several
files you want to share at once but the file transfer service you’re using can
accept only single-file uploads. Put all the files into an archive and then
upload that single file, which the recipient can then download and unpack to
see all the files you’ve shared.
7-Zip is one of the most popular compression programs, but some other options include WinZip, PeaZip, and the compression features built-in to your operating system. You can learn the differences between some of these compression tools if you’re not sure which one to use.
File Transfer
Example
Now that you have a good idea of how to
determine which transfer service you might need and what your options are for
sending large files online, follow along with this example of ShareDrop to see
how it looks in action:
Step 1: Open the ShareDrop website.
Step 2: Press the plus sign at the top right.
Note: If you’re transferring the large files to other people on your same network — those that share the same public IP address as you —skip down to Step 5; ShareDrop will automatically identify other local users.
Step 3: Copy the link you see in the text box and share it with the person
you’re sending the file to.
Step 4: Press Got it! on your page.
At this point, you should see all the other
people who have opened the link you shared.
Step 5: Select the avatar for the person you want to send the file to.
Everyone is self-identified at the bottom of their own page.
Step 6: Choose the file from your computer that you want to send.
Step 7: Press Send on the
ShareDrop page, and then instruct the recipient to press Save on their page.
That’s it! Now, you can watch the blue
progress bar around the recipient’s avatar to check how long it will take to
complete the P2P transfer. A green checkmark will briefly show when the file
transfer finishes.
