I have problems unzipping a product
Are you on a Mac?
A common issue on Mac is that bigger files often won't unzip correctly. Either they aren't unzipping at all - or they unzip parts of the product. If you have this issue, we recommend that you use Keka.
Some archives will be split into parts. They will typically have numbered file extensions such as .z01 or .zx01, .z02 or .zx02, etc. If this is the case, simply download all the archives. Once the download is completed, start by extracting the first archive. This will start a domino effect and automatically extract all the subsequent archives.

ZIP-file is too large
If your ZIP-file is very large, you may need to use a third-party tool like 7-ZIP. This tool is freeware and can handle most archived files.
ZIP-file is corrupted
If your ZIP-file is corrupted or contains inconsistencies, you may need to repair the file. One great free tool to repair on Windows is Object Fix Zip
Another option is, if you have one, to use a Mac. Run the following command:
zip -FF /Users/fd/yourzipfile.zip –out /Users/fd/yourzipfile2.zip
Of course, replace /Users/fd/yourzipfile.zip with the location of your zip file.
You may also be able to re-download the ZIP-file, if from the internet. Corrupted ZIP-files are often caused by unfinished downloads. In addition, make sure you have sufficient free disk space on your drive!
Repair ZIP-file with WinRAR
WinRAR has proven to be effective in repairing invalid ZIP-files.
- Open WinRAR and navigate to the folder of the corrupted archive. This can be a Temp folder or your Downloads folder.
- Select the RAR or ZIP file. Click the Repair button in toolbar, and click Repair archiver
- In the dialog box, choose the location where you want to save the repaired ZIP-file. Click OK to confirm
- After repairing, navigate to the folder where you saved the repaired archive file. Try to open and extract.
