664 or 644?

[Nickji]

I have read in various posts that to fix the problem where a backup or upgrade has changed file permissions to 666 these need to be changed to 664.  In other posts it says to change them to 644.  Which is correct?

... and which files need to be chnaged? all .php files throughout the whole site?

@NickjiHi,

On the below URL you can find the recommended permission from Magento and how to set them.

Out of 664 and 644, 644 is better as only the Owner of the file has the write privilege.

Problem solved? Please give Kudos and select answer as Solution.

Thanks   I had a quick look at the page, but I have decided to go with a managed shopping cart solution as I don't have the time to devote to learning the intricacies of Magento
