真正的大文件很常见。随着我们媒体质量的提高，文件也随之提高。压缩软件(Compression software)可以将高清质量的电影(HD-quality film)压缩成一个千兆字节的文件(gigabyte file)，但对大多数人来说既费时又不切实际。
当你想移动这么大的文件时会发生什么？你能把一个大文件分成更小的块以使共享更容易吗？
以下是使用免费软件将文件拆分为多个文件的方法。
GSplit是一个免费的文件分割工具，您可以使用它来分割那些大文件。使用GSplit，您可以：
· 控制(Control)单独的分割文件(split file)大小和输出文件(output file)类型
· 将(Unite)您的拆分文件合并为一个文件
· 为拆分文件创建(Create)自定义命名方案
· 使用(Use)Express 文件(Express file)拆分器进行快速文件拆分(file splitting)
· 创建自联合(Create self-uniting)拆分文件
首先(First)，下载并安装GSplit。准备就绪后，打开GSplit并从左侧菜单中选择原始文件。(Original File)浏览(Browse)到要拆分的文件。现在，从菜单中选择目标文件夹(Destination Folder)，然后浏览到您希望多个拆分文件结束的位置。
在移动到Split File!选项（进行拆分的位置），打开“类型和大小(Type and Size)”菜单。您可以使用GSplit以几种不同的方式将文件拆分为多个文件。例如，你可以指定你想要多少个输出文件(output file)，GSplit会告诉你每个(GSplit)分割片(split piece)有多大。或者，您可以设置每个输出文件(output file)的大小，GSplit会告诉您将创建多少个文件。
还有根据文件内容以指定模式拆分文件的选项（尽管这是一个高级选项）。
确定文件拆分配置后，选择Split File!，然后Split! GSplit将开始处理您的文件。将文件拆分为多个文件所需的时间取决于输出选项的复杂性和原始文件的大小。
(GSplit)当您想要重新组装文件时，GSplit创建了一个方便的可执行文件。您将在与拆分文件相同的文件夹中找到可执行文件。双击(Double-click)可执行文件以启动重组过程(reassembly process)并确认输出文件(output file)的位置。默认的可执行文件名称是disk1.EXE，但如果您创建自定义命名方案，它将与您的设置匹配。
完成文件拆分后，请查看如何在同一网络上的计算机之间传输文件( how to transfer files between computers on the same network)。
使用 GUnite 手动重组文件(Manually Reassemble Files With GUnite)
GSplit包含一个名为GUnite的(GUnite)重组工具(reassembly tool)。从GSplit顶部菜单中，选择Unite。GUnite 将在新窗口中打开。
浏览(Browse)到拆分文件的位置。您必须找到包含GSplit片段、带有.GSD文件扩展名(file extension)的文件夹，如下图所示(image below)。
选择序列中的第一个文件，然后选择输出(Select Output)以确认重建后文件的位置。最后，选择恢复文件(Restore File)。与文件拆分过程一样，恢复过程(restoration process)需要时间，具体取决于文件大小(file size)、块数等。
您(Did)知道流行的免费存档工具 7-Zip 还包括一个文件分割工具吗？您的输出文件将成为存档的一部分，这也可以节省您的磁盘空间。对更多免费工具感兴趣？查看我们的 Windows 最佳免费工具列表(our list of the best free tools for Windows)。
回到最好的文件拆分器。使用 7-Zip，您可以：
· 将大文件拆分(Split)成多个文件
· 自定义小文件部分的数量
· 加密你的输出文件
· 使用(Use)多种压缩算法(compression algorithms)来减小文件大小
首先(First)，右键单击要拆分为较小部分的文件，然后选择7-Zip > Add to Archive。给你的档案一个名字。在Split to Volumes, bytes下，输入您想要的拆分文件的大小。下拉菜单中有几个选项，尽管它们可能与您的大文件不对应。如果是这种情况，您可以输入自定义输出文件大小(custom output file size)。
准备好后按OK，让 7-Zip 将大文件拆分成更小的文件。
当您要重建文件片段时，在存档中找到第一个拆分文件(split file)，右键单击并选择7-Zip > Extract to [File Name]。您将在输出文件夹(output folder)中找到您的原始文件。
FFSJ(J)，或F astest File S plitter(F) and Joiner，是您拆分和连接大文件的最终选择。使用FFSJ，您可以：
· 将大文件拆分(Split)成多个文件
· 自动(Automatically)删除源文件
· 加密输出(Encrypt output)文件以提高安全性
您会发现易于使用的选项，允许您将文件拆分为相等的部分或使用特定文件大小进行拆分。还可以选择在拆分文件后删除源文件(source file)，或加密输出文件以提供额外保护。如果您选择加密文件，则必须在文件拆分器(file splitter)开始之前输入密码。
要使用FFSJ(FFSJ)拆分大文件，请选择输入文件(input file)，然后选择输出文件位置(output file location)。同样，当您想要加入拆分文件时，打开FFSJ，然后选择Joining选项卡。浏览(Browse)到包含第一个拆分文件部分(split file part)的文件夹，然后为您的重建文件添加一个输出文件夹(output folder)。

How to Split a Large File into Multiple Smaller Pieces
Really big files are a common occurrence. As the quality of our media increasеs, so do the fіles along with it. Compreѕsion software can squeeze an HD-quality film into a single gigabyte file, but it is time-consυming and impraсtical for most people.
What happens when you want to move such a large file? Can you break a large file into smaller chunks to make sharing easier?
Here’s how you split a file into multiple files using free software.
GSplit is a free file splitting tool you can use to split up those large files. With GSplit, you can:
· Control the individual split file sizes and the output file types
· Unite your split files into a single file
· Create a custom naming scheme for split files
· Use the Express file splitter for rapid file splitting
· Create self-uniting split files
First up, download and install GSplit. When ready, open GSplit and select Original File from the menu on the left. Browse to the file you want to split. Now, select Destination Folder from the menu, and browse to where you want the multiple split files to end up.
Before moving to the Split File! option (where the splitting takes place), open the Type and Size menu. You can use GSplit to split a file into multiple files in a few different ways. For example, you can specify how many output files you want, and GSplit will tell you how big each split piece will be. Alternatively, you can set the size of each output file, and GSplit will tell you how many files that will create.
There is also the option to split the files in a specified pattern according to the file contents (although this is an advanced option).
Once you decide the file splitting configuration, select Split File!, then Split! GSplit will begin processing your file. The time it takes to split a file into multiple files depends on the complexity of the output options and the size of the original file.
GSplit creates a handy executable for when you want to reassemble your files. You’ll find the executable in the same folder as the split files. Double-click the executable file to launch the reassembly process and to confirm the location of the output file. The default executable name is disk1.EXE, although if you create a custom naming scheme it will match your settings.
Once you finish splitting your files, check out how to transfer files between computers on the same network.
Manually Reassemble Files With GUnite
GSplit includes a reassembly tool called GUnite. From the GSplit top menu, select Unite. GUnite will open in a new window.
Browse to the location of your split files. You must locate the folder containing the GSplit pieces, carrying the .GSD file extension, as per the image below.
Select the first file in the sequence, then Select Output to confirm where you want the file after reconstruction. Finally, select Restore File. Like the file splitting process, the restoration process takes time depending on the file size, number of chunks, and so on.
Did you know that the popular free archive tool, 7-Zip, also includes a file splitting tool? Your output files will form part of an archive, which could save you disk space, too. Interested in more free tools? Check out our list of the best free tools for Windows.
Back to the best file splitters. With 7-Zip, you can:
· Split large files into multiple files
· Customize the number of small file parts
· Encrypt your output files
· Use a variety of compression algorithms to decrease file sizes
First up, right-click the file you want to split into smaller pieces, then select 7-Zip > Add to Archive. Give your archive a name. Under Split to Volumes, bytes, input the size of split files you want. There are several options in the dropdown menu, although they may not correspond to your large file. If that’s the case, you can enter a custom output file size.
Press OK when you are ready and let 7-Zip split your large file into smaller bits.
When you want to reconstruct your file pieces, find the first split file in the archive, right-click and select 7-Zip > Extract to [File Name]. You’ll find your original file in the output folder.
FFSJ, or the Fastest File Splitter and Joiner, is your final option for splitting and joining large files. With FFSJ, you can:
· Split large files into multiple files
· Automatically delete source files
· Encrypt output files for extra security
You’ll find easy to use options allowing you to split your file into equal parts or split using specific file sizes. There is also the option to delete the source file after splitting the file, or to encrypt the output files for extra protection. If you choose to encrypt the files, you must enter a password before the file splitter begins.
To split a large file with FFSJ, select your input file, then the output file location. Similarly, when you want to join the split files, open FFSJ, and select the Joining tab. Browse to the folder containing the first split file part, then add an output folder for your reconstructed files.
What Is The Best Free Large File Splitter?
You have several options to split a file into multiple files. The three options are easy to use and have different file splitting options. For instance, you can use 7-Zip to split and compress your output files, potentially saving space on your hard drive.
Once you’ve split your files, you might want to send them to your friends. Check out the best ways to send large files as email attachments.
