Part 4. Additional to Avoid ZIP File Corruption
Remember these five essential tips to lessen the likelihood of having your ZIP files damaged in future:
- Always regularly backup important files like ZIP archives. Keep backups on external or cloud storage so you have a ‘spare’ copy if something goes wrong.
- Check for software reliability and credibility in creating and extracting ZIP files. For example, WinRAR, 7-Zip, and WinZip are commonly used data management tools that are continuously updated for increased security.
- Never stop compressing or decompressing a file while it is being processed. These can be corrupted by a sudden loss of power or forced shutdowns. Uninterruptible Power Supply (UPS) can save data during blackouts.
- Make sure you verify the source when downloading a Zip file from the internet. Checksums such as MD5 and SHA-256 may be available for verifying the download’s integrity.
- Use dependable antivirus software to keep malware away from your computer which might end up damaging your files. Check your computer frequently for malware and viruses.
