Resolving Database and Data Store Files Were Not Successfully Extracted Error Message

Zipping two or more files enables you to create a compressed version of the original files that is smaller than the actual file size. These files are mainly used by network and database administrators to send data on a network. Corruption in Zip files primarily occurs due to CRC (Cyclic Redundancy Check) errors, faulty network hardware, file version mismatch, application malfunctioning, malicious software like virus and more. Under these circumstances, the data saved in the Zip file becomes inaccessible. To successfully recover the Zip file data, you will need to restore it from the latest backup. However, in absence of an up-to-date backup, you will need to repair the corrupted Zip file using powerful repair tools.

As a practical instance, you encounter any of the below error messages when you attempt to unpack or extract the zipped database:

"Database and data store files were not successfully extracted from zip file. Error inflating: invalid block type"

Or

"Database and data store files were not successfully extracted from zip file. Error inflating: oversubscribed dynamic bit lengths tree"

Or

"Database and data store files were not successfully extracted from zip file. An error occurred while copying the zip file to the course directory."

After any of the above error messages appear, the data stored in the Zip file becomes inaccessible.
