45,009 PointsThe \ character is an escape character, this means that the character after the \ will not be run by code, for example by using backslashes you could initialize double quotes in a variable.
$actor = "Dwayne \"The Rock\" Johnson";
The value of the variable will be: Dwayne "The Rock" Johnson.
If you want a backslash to show up use a backslash to escape the backslash. So:
echo 'You deleted C:\\*.?';

2,605 PointsMy apologies. I did not put the code there. Wondering why these 2 are the same.
// Outputs: You deleted C:\*.*?
echo 'You deleted C:\\*.*?';
// Outputs: You deleted C:\*.*?
echo 'You deleted C:\*.*?';
