How about

^[a-zA-Z]:\\(\w+\\)*\w*$

Then in JS, you could check if a string matches by

/^[a-zA-Z]:\\(\w+\\)*\w*$/.test(yourString)

Hi, Thanks for quick reply. The folder d: is not constant. It can anything like c or d or e.

Hi, It is working fine for the folder which is having no space between the folder name like 'ProgramFiles' but it is not working working for space between the folder name like 'Program Files'

Then the regex would be ^[a-zA-Z]:\$[a-zA-Z0-9.\-*.+]+([ ][a-zA-Z0-9.\-*.+]+)*\$*([a-zA-Z0-9.\-*.+]+([ ][a-zA-Z0-9.\-*.+]+)*)*$

This is a bad regex. It would validate myPath//Is//////Flawed
