Some files are too huge in size that there are often difficulties in trying to transfer them due transfer limitation in some apps, disconnect half way during the transfer, etc. In Windows 11, files can be split into multiple parts using a file archiver/compression software that supports multi-parts compression. This guide will show you how to split a file into multiple files in Windows 11 using WinRAR or 7-Zip file archiver.

Most compression software will allow you to split volumes during compression. We recommend WinRAR and 7-Zip as they are the most popular file archiver software for Windows. If you are using other file compression software, you can look for its own multi-part compression option usually called “split to volumes” or similar during “add to archive” process.

If you have one giant file that you want to split into multiple smaller files/parts, you can split the file into multiple volumes using compression method. To summarize, you zip a file with a compression tool that allows you to split the file into multiple volumes during the archive process. You can then transfer the archived parts to wherever you want and unzip/extracted them at your destination to become one single file again.

Under Archive format, you can choose between RAR or ZIP. We recommend choosing ZIP because RAR can only be read and extracted by WinRAR. If your other computer that you want to transfer the archived files to doesn’t have WinRAR, you can’t extract the file if the parts are in RAR format. As for ZIP format, Windows itself will be able to extract it without the need to install WinRAR or any other file archiver.

Under Archive format, 7z is selected by default. We recommend to choose ZIP format so that it can be read and extracted by any other compression software. 7z files can only be read and extracted by 7-Zip file archiver.

The downside of using 7-Zip (compared to WinRAR) is that files archived and split by 7-Zip require at least a compression tool to extract them. Windows cannot extract the files split using 7-Zip even if they are in ZIP format.

To extract the compressed files, right-click one of the archived parts and select Show more options > 7-Zip > Extract Files.

Note that all the compressed parts have to be in the same folder when you extract them. If one or more parts are missing, the extraction will fail due to incomplete parts.
