How to Fix: CRC error on a file splitted by WinRar
CRC error on a file splitted by WinRar extraction issue.
📋 Table of Contents
A CRC (Cyclic Redundancy Check) error on a file extracted from a WinRAR archive can be frustrating, especially when dealing with split archives. This issue typically affects users who have copied parts of an archive to the same directory and attempt to extract it. The problem arises because some files contain data that is present in both the original archive and the local copy, causing the CRC check to fail.
The CRC error can be caused by various factors, including incorrect file handling during extraction or corruption during transmission. When dealing with split archives, it's essential to follow proper procedures to ensure accurate and complete extraction.
⚠️ Common Causes
- One main reason for this issue is that WinRAR uses a CRC check to verify the integrity of files during extraction. If the CRC check fails, the file may be corrupted or incomplete, leading to an error. This can occur when files are split across multiple archive parts and are not properly aligned during extraction.
- Another possible cause is incorrect handling of files during extraction. If the extraction process does not correctly handle the split archives, it may result in CRC errors.
🛠️ Step-by-Step Verified Fixes
Re-extracting with WinRAR's 'Extract to' option
- Step 1: Open the WinRAR archive and select the 'Extract to' option.
- Step 2: Choose the directory where you copied the parts of the archive, including both Part 1 and Part 2.
- Step 3: Click on the 'Extract' button to start the extraction process. WinRAR will attempt to re-extract the entire file from both parts of the archive.
- Step 4: Wait for the extraction process to complete. If everything goes smoothly, you should be able to extract all the files without any CRC errors.
Manually merging and re-extracting with WinRAR
- Step 1: Open both parts of the archive (Part 1 and Part 2) in WinRAR.
- Step 2: Select the 'Add to Archive' option and add the contents of both parts together, making sure that all files are properly aligned.
- Step 3: Click on the 'Extract to' option and choose the desired extraction directory.
- Step 4: Click on the 'Extract' button to start the re-extraction process. This method requires more manual effort but can be effective in resolving CRC errors.
✨ Wrapping Up
To resolve a CRC error when extracting files from a split WinRAR archive, try using WinRAR's 'Extract to' option or manually merging and re-extracting with WinRAR. If you're not comfortable with these methods or if the issue persists, consider seeking assistance from a technical support specialist or exploring alternative extraction tools.
