Frequently Asked Questions

Questions And Answers

 
Q: Can ZipRecovery repair my Zip archive?
A:

The effective way to find out if a Zip archive is recoverable is to try the demo version of ZipRecovery on it. Visit the Demo page for a free copy of the demo.

Product specifications with lists of items recovered and not recovered is available at the Product Information page.

Note: Always backup your original corrupted Zip archive before proceeding with any recovery activity!

 
Q: What limitations does the demo version of ZipRecovery have?
A: The demo version recovers only one file in the broken archive while replacing data in others with demo placeholder. Commercial version will recover all the files possible.

If due to archive damage some part of the archived file has been lost, the full version of ZipRecovery will not be able to get back the file and will skip it.

 
Q: I have tried the demo. How do I decide whether to purchase the full version of ZipRecovery?
A:

Evaluating the results of demo recovery can help in making the decision.

 
Q: What are the differences between product licenses?
A:

Details of current licensing scheme are described at the Licensing page.

 
Q: Why do results of recovery contain less data than the original Zip archive?
A: This is normal. The damaged parts of your Zip archive will convert to zero size on output. The other common reason of file size decrease is when some of features of the original archive are not supported and therefore absent from the recovered archive.
Demo-recovered archive is smaller because it mostly consists of demo placeholders than actual data.
 
Q: Running ZipRecovery from command line (through Windows Start -> Run menu).
A:

If your license type is Enterprise or Service, you can run ZipRecovery from command line and use these calls in your batch files. Standard version does not support command line. The format for command line call is:

zr.exe <original filename with path> "<path to directory to store the recovered file(s)>"
(without angle brackets).

Please note that the directory for recovered file(s) should be created before starting the recovery.

Command line mode supports patterns '*' (replaces group of symbols) and '?' (replaces one symbol).

 
Q: I get a CRC error when extracting some of my files from the archive. After using ZipRecovery, the faulty files are not present in the recovered archive. Is it possible to get them back as well?
A:

Try the following:

  1. Create a registry value called FilesToRepairCRC (type REG_SZ) in HKEY_CURRENT_USER\Software\Recoveronix\ZipRecovery
  2. List the extensions of the files that cause CRC error, using semicolon as a divider and asterisk as a filename wildcard (e.g. *.jpg;*.txt)
  3. Run the recovery again
