It is also more practical in many everyday situations.\n\nFor example:\n- Sending files through email services with attachment limits.\n- Saving large files across multiple flash drives or older storage media.\n\nThe good news is that **WinRAR** has this feature built in, and the process is very straightforward.\n\n## Quick Size Guide (Before You Start)\n\nChoosing the right part size will save a lot of trouble for both uploader and downloader.\n\n| Use Case | Recommended Part Size | Why |\n|---|---:|---|\n| Email attachment workflow | `20M` to `24M` | Stays under common 25 MB limits after metadata overhead. |\n| Messaging apps / quick sharing | `50M` to `100M` | Easier to retry if one upload fails. |\n| Cloud drive with unstable internet | `100M` to `250M` | Good balance between speed and retry cost. |\n| Flash drive transfer (older devices) | `500M` | Safer for mixed storage quality and copy interruptions. |\n| Archival backups on local disk | `1000M` or more | Fewer parts to manage when network reliability is not a concern. |\n\nIf you are unsure, start with **`100M`**. It is usually the safest practical default.\n\n## #1 Install WinRAR First\n\nIf WinRAR is not installed yet, download it first. It is also one of the [essential utilities we recommend after a Windows 11 installation](/blog/to-do-after-install-windows11).\n\nUse these download references from your publishing workflow:\n\n\n\n\nFor the latest official release source, you can also check [Official WinRAR Download](https://www.win-rar.com/download.html?&L=0).\n\n\nWinRAR 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.\n\n\nInstallation is the same as any normal `.exe` app: run installer, follow prompts, done.\n\n## #2 Split a File into Multiple RAR Parts\n\nAfter WinRAR is installed, follow these steps.\n\n\n \n **Prepare your target file or folder**\n Decide which file or folder you want to split into multiple parts.\n \n\n \n **Open the WinRAR archive dialog**\n Right-click the file/folder and choose **Add to archive...**.\n \n\n \n **Configure split-volume settings**\n In the settings window, focus on these fields:\n - **Archive name:** Change the output file name if needed.\n - **Archive options:** Enable **Create solid archive** and **Add recovery record** for better integrity.\n - **Split to volumes, size (most important):** Set the size for each part. You can pick presets or type manually, such as `100M` for 100 MB per part.\n \n\n \n **Start the split process**\n Click **OK** and wait. WinRAR will generate files such as `.part1.rar`, `.part2.rar`, and so on.\n \n\n\n![WinRAR archive settings window showing how to split files into multiple volume parts.](/images/_posts/apps/winrar/split_rar.webp \"WinRAR split-to-volumes configuration in Windows.\")\n*The key setting is in **Split to volumes, size**.*\n\n## #3 How to Rejoin and Extract the Parts\n\nTo avoid extraction failure on the receiver side, there is one rule you must emphasize.\n\n### Keep All Parts in One Folder\n\nAll parts must be in the same directory, for example:\n- `file.part1.rar`\n- `file.part2.rar`\n- `file.part3.rar`\n\nIf one part is missing, extraction will fail.\n\n### Extraction Steps\n\n\n \n **Make sure all parts are in one folder**\n Verify every part file is present and stored in the same directory.\n \n\n \n **Start extraction from the first part**\n Right-click `part1.rar` and choose **Extract Here** or **Extract to...**.\n \n\n \n **Let WinRAR merge automatically**\n WinRAR will read the remaining parts and combine them during extraction.\n \n\n\nThat is it. Simple, practical, and very useful when handling large files.\n\n## Common Problems and How to Fix Them\n\nIf extraction fails, it is usually one of these:\n\n1. **One part is missing**\n Download the missing part again. All part files must be complete.\n2. **One part is corrupted**\n Re-download only the damaged part (not the whole set) and retry extraction.\n3. **Wrong extraction start point**\n Always extract from `part1.rar`, never from `part2+`.\n4. **File names changed accidentally**\n Keep original naming sequence. Renaming one file can break automatic chain reading.\n\n## Practical Integrity Check (Optional but Recommended)\n\nFor important files, verify after upload:\n\n\n \n **Test extraction locally first**\n Extract your own split archive once before sharing it.\n \n\n \n **Store all parts in a clean folder**\n Avoid mixed folders with old test archives that use similar names.\n \n\n \n **Use WinRAR recovery record for resilience**\n Keeping **Add recovery record** enabled improves tolerance against minor data damage.\n \n\n\nFollowing these checks dramatically reduces “archive is corrupt” complaints from recipients.\n"}
