如何将大型文件上传到SkyDrive，Dropbox或电子邮件
Do you need to upload a very large file to store online or email to a friend? Unfortunately, whether you’re emailing a file or using online storage sites like SkyDrive, there’s a limit on the size of files you can use. Here’s how to get around the limits.
您是否需要上传很大的文件以在线存储或通过电子邮件发送给朋友？ 不幸的是，无论您是通过电子邮件发送文件还是使用在线存储站点(例如SkyDrive)，都可以使用的文件大小受到限制。 这是解决限制的方法。
Skydrive only lets you add files up to 50 MB, and while the Dropbox desktop client lets you add really large files, the web interface has a 300 MB limit, so if you were on another PC and wanted to add giant files to your Dropbox, you’d need to split them. This same technique also works for any file sharing service—even if you were sending files through email.
Skydrive仅允许您添加最大50 MB的文件，而Dropbox桌面客户端允许您添加非常大的文件，而Web界面的最大限制为300 MB，因此，如果您在另一台PC上并想向Dropbox添加大型文件，您需要将它们拆分。 即使您通过电子邮件发送文件，此技术也适用于任何文件共享服务。
There’s two ways that you can get around the limits—first, by just compressing the files if you’re close to the limit, but the second and more interesting way is to split up the files into smaller chunks. Keep reading for how to do both.
可以通过两种方法来克服限制：一种是在接近极限时通过压缩文件来进行限制，而第二种更有趣的方法是将文件拆分为较小的块。 继续阅读如何做这两者。
只是缩小文件！(Just Shrink the File!)
So what can you do if you really need to share a larger file but have hit the upload limit? If you’re right near the limit, you might be able to get by with just compressing the original file. You could just right-click and select Send to –> Compressed Folder, but you’ll save even more space by using another compression tool that’s more efficient than zip format.
那么，如果您确实确实需要共享更大的文件却达到了上传限制，该怎么办？ 如果您即将达到极限，则只需压缩原始文件就可以解决问题。 您可以右键单击并选择“发送到–>压缩文件夹” ，但是使用另一个比zip格式更有效的压缩工具可以节省更多空间。
We recommend installing the freeware 7-Zip program; then, just select Add to yourfile.7z and your file will be compressed in 7-Zip format. Depending on your file, you can often shave several megabits off of a 50Mb file so you can upload it easily.
我们建议安装免费的7-Zip程序； 然后，只需选择“添加到您的文件.7z” ，您的文件将以7-Zip格式压缩。 根据文件的不同，您通常可以将50Mb的文件削掉几兆位，以便轻松上传。
将文件拆分为块 (Split the File into Chunks)
But what if your file is still too big? It’s 7-Zip to the rescue again! This time, open the 7-Zip window and browse to the folder where your file is saved. Right-click the file you need to upload and select Split File.
但是，如果您的文件仍然太大，该怎么办？ 又是7压缩救援！ 这次，打开7-Zip窗口并浏览到保存文件的文件夹。 右键点击您需要上传的文件，然后选择拆分文件。
This will open a dialog asking where to save the split files and what size to split them to. You can select the standard floppy, CD, or DVD sizes, but since you’ll likely not be using a floppy (does anyone still use those today?) just enter the size you need in the box. We entered 50Mb to break our file into 50Mb chunks so we can easily upload them to SkyDrive. Press Ok when you’re finished. If you were using Email, you could split the files up into 10 MB chunks and they will probably go through.
这将打开一个对话框，询问将拆分文件保存在何处以及将拆分文件拆分成什么大小。 您可以选择标准的软盘，CD或DVD大小，但是由于您可能不使用软盘(今天有人还在使用软盘吗？)，只需在框中输入所需的大小即可。 我们输入50Mb将文件分成50Mb块，因此我们可以轻松地将它们上传到SkyDrive。 完成后按确定。 如果您使用的是电子邮件，则可以将文件分成10 MB的块，它们可能会通过。
Now, just wait a few moments while 7-Zip splits your file into nice, smaller files.
现在，请稍等片刻，然后7-Zip将您的文件分割成更小的较小文件。
上传或通过电子邮件发送文件 (Upload or Email Your Files)
Once the splitting process is finished, you can try to upload your files again, this time selecting the new split files. And if you picked the correct file size to split the file, your new files should upload just fine. So much for file size limits!
分割过程完成后，您可以尝试再次上传文件，这次选择新的分割文件。 而且，如果您选择了正确的文件大小来分割文件，则新文件应该可以正常上传。 文件大小限制就这么多！
恢复原始文件 (Restore the Original File)
The only problem is, now you’ve got a bunch of files named yourfile.ext.001, yourfile.ext.002, and more. What do you do with these files? You’ll need to convert them back into the original file. To do this, just save the files in the same folder, and browse to that folder in 7-Zip. Right-click on the first file with the extension .001 and select Combine Files.
唯一的问题是，现在您有一堆名为yourfile.ext .001， yourfile.ext .002等的文件。 您如何处理这些文件？ 您需要将它们转换回原始文件。 为此，只需将文件保存在同一文件夹中，然后在7-Zip中浏览到该文件夹。 右键单击扩展名为.001的第一个文件，然后选择合并文件。
7-Zip will detect the other files, and ask where you want to save them. Press Ok to combine the files, and seconds later you’ll have your original file again.
7-Zip将检测其他文件，并询问您要将它们保存在哪里。 按“确定”合并文件，几秒钟后，您将再次拥有原始文件。
That’s it! Now you can upload any sized files you want, share them, and then get the original file back easily. You could do this with many different file archival programs, but 7-Zip works great and is free, so we recommend it. Whether you need to compress a file, split it, or combine the split parts, it’ll work great for everything.
而已！ 现在，您可以上传所需的任何大小的文件，共享它们，然后轻松地取回原始文件。 您可以使用许多不同的文件归档程序来执行此操作，但是7-Zip很好用并且免费，因此我们建议使用。 无论您需要压缩文件，拆分文件还是合并拆分部分，它都将为所有工作提供出色的支持。
