Error: E02019 - File can not be extracted
Symptom:
This error will happen when you're installing or updating the game and is created by a corrupt file being downloaded in place of the file you needed.
Solution:
To solve this problem, you will need to download a clean copy of the file that is corrupt. In the error message, you will receive a file like at the end, for example:
"Sounds\music\Pak_001.pak"
This is the file that has been corrupted and will need to be corrected. This can easily be done by closing the launcher and searching for this file on your computer.
Once this file has been found, delete the file and do a complete system restart.
Now restart the launcher and begin updating your client like normal.
Checkpoint:
If you notice this error is happening repeatedly, this may indicate that you have a problem with your HDD. I suggest you run a manual check just to make sure everything is working correctly.
Open the Command Prompt as Administrator
Type the following command;
chkdsk/f/r
The message "Do you want this disk to be checked the next time your system restarts? (Y/N)" will appear, type Y and press Enter
Restart your computer and allow the Check Disk system run, this may take some time.
If there are any problems located on your disk, this system will normally automatically repair it.
