Regular Expression For Folder Name

[krishna shinde]

Hi All,

                  i want to validate the folder name when user create or rename a folder . for that i am using regular expression validator.
as per standards a folder name should not have this characters *   /   >  <  ?  \  | : , i am trying to generate regular expression for that but failed. If anyone have that expression or any new way for validation then please let me know.

Thanks 
Krishna

Hello Krishna

For validating the folder names, you may use-
^([a-zA-Z0-9][^*/><?\|:]*)$

Hi!

You are used wrong quantificator -- empty string will be valid folder name. :)
You may use {1,}

var regexp:RegExp;
var string:String;
regexp = /^[^\\\/:*?"<>|]{1,}$/g; // unicode folder name
string = 'EH\'46u4 6y4y6 ХШЩзшщртіЇ'; // valid unicode folder name
trace(string.match(regexp));
regexp = /^[\w\s ']{1,}$/g; // non-unicode folder name
string = 'EH\'46u4 6y4y6 ';
trace(string.match(regexp));

output:
EH'46u4 6y4y6 ХШЩзшщртіЇ
EH'46u4 6y4y6

Hi guys ,

      thanks for reply , i have tried both option but no one works.
what i exactly want is when user type folder name in textinput box , i want to restrict him so that user is not able to insert  *   /   >  <  ?  \  | : , character in textinput. for this i am using regular expression validator.

cant we use restrict here. Instead of validating later?
