I'm trying to install a file-based blog engine in XAMPP, but all of these projects require write permissions to be changed. I'm assuming they are not talking the Windows setting that can be accessed through 'properties'. Any idea where/how to change this? seems like an easy question but i'm coming up short. Thank you.
Windows is generally less restrictive about read/write-permissions. If you did not install XAMPP into C:\ProgramFiles chances are good, that setting file-permissions does not apply to your installation. In the unlikely case, that your PHP-log shows warnings/errors regarding file permissions, then changing them like you described (with settings > permissions) is the way to go. You just have to find out, under which user name apache is running (via Administrative Tools, Services) and add read/write permissions for that user in the appropriate folder.
In short, you can ignore the sections on setting file permissions on Windows.
Basically, the user that Apache runs as needs to able to write to the files.
So firstly, check process list to determine which user that is. Then simply give that user write permission to those files/folders.
(I'm not a XAMPP or Win 7 user so can't give exact directions but I'm sure you'll work it out.)
