How to Split Large Files into Multiple Parts with WinRAR
Iwan Efendi3 min
A practical step-by-step guide to splitting large files into smaller RAR parts with WinRAR, including ideal size settings and extraction tips.
As a blogger who occasionally shares large game files or software packages, I often get the same request: "Can you split this into parts so it is easier to download?"
And honestly, that request makes total sense.
When a file is divided into smaller chunks, users can download part by part with less risk of a failed full download. It is also more practical in many everyday situations.
For example:
Choosing the right part size will save a lot of trouble for both uploader and downloader.
If you are unsure, start with
If WinRAR is not installed yet, download it first. It is also one of the essential utilities we recommend after a Windows 11 installation.
Use these download references from your publishing workflow:
WinRAR Installer (32-bit)3.1 MBDownload
WinRAR Installer (64-bit)3.4 MBDownload
For the latest official release source, you can also check Official WinRAR Download.
Installation is the same as any normal
After WinRAR is installed, follow these steps.
The key setting is in Split to volumes, size.
To avoid extraction failure on the receiver side, there is one rule you must emphasize.
That is it. Simple, practical, and very useful when handling large files.
If extraction fails, it is usually one of these:
For important files, verify after upload:
Following these checks dramatically reduces “archive is corrupt” complaints from recipients.
- Sending files through email services with attachment limits.
- Saving large files across multiple flash drives or older storage media.
Quick Size Guide (Before You Start)
| Use Case | Recommended Part Size | Why |
|---|---|---|
| Email attachment workflow | 20M to 24M | Stays under common 25 MB limits after metadata overhead. |
| Messaging apps / quick sharing | 50M to 100M | Easier to retry if one upload fails. |
| Cloud drive with unstable internet | 100M to 250M | Good balance between speed and retry cost. |
| Flash drive transfer (older devices) | 500M | Safer for mixed storage quality and copy interruptions. |
| Archival backups on local disk | 1000M or more | Fewer parts to manage when network reliability is not a concern. |
100M. It is usually the safest practical default.
#1 Install WinRAR First
Free Application
WinRAR can be used for free. You may see a purchase reminder for the Pro license, but core features remain usable without a hard time limit.
.exe app: run installer, follow prompts, done.
#2 Split a File into Multiple RAR Parts
1
Prepare your target file or folder
Decide which file or folder you want to split into multiple parts.
2
Open the WinRAR archive dialog
Right-click the file/folder and choose Add to archive....
3
Configure split-volume settings
In the settings window, focus on these fields:
- Archive name: Change the output file name if needed.
- Archive options: Enable Create solid archive and Add recovery record for better integrity.
- Split to volumes, size (most important): Set the size for each part. You can pick presets or type manually, such as
100Mfor 100 MB per part.
4
Start the split process
Click OK and wait. WinRAR will generate files such as
.part1.rar, .part2.rar, and so on.Zoom
#3 How to Rejoin and Extract the Parts
Keep All Parts in One Folder
All parts must be in the same directory, for example:file.part1.rarfile.part2.rarfile.part3.rar
Extraction Steps
1
Make sure all parts are in one folder
Verify every part file is present and stored in the same directory.
2
Start extraction from the first part
Right-click
part1.rar and choose Extract Here or Extract to....3
Let WinRAR merge automatically
WinRAR will read the remaining parts and combine them during extraction.
Common Problems and How to Fix Them
- One part is missing Download the missing part again. All part files must be complete.
- One part is corrupted Re-download only the damaged part (not the whole set) and retry extraction.
- Wrong extraction start point
Always extract from
part1.rar, never frompart2+. - File names changed accidentally Keep original naming sequence. Renaming one file can break automatic chain reading.
Practical Integrity Check (Optional but Recommended)
1
Test extraction locally first
Extract your own split archive once before sharing it.
2
Store all parts in a clean folder
Avoid mixed folders with old test archives that use similar names.
3
Use WinRAR recovery record for resilience
Keeping Add recovery record enabled improves tolerance against minor data damage.
