How do you specify a folder path in batch?

Question

In Batch, I know you can always specify a folder path in batch/cmd, for example,

echo %RANDOM% >> C:\Users\User\Logs\log.txt

or

start C:\Windows\System32\cmd.exe

But what if for example, your batch file was used in a product, where these locations may differ or not exist? How would you specify?

I suspect you may want `%~dp0` - the path to the batch file that is currently executing. — dbenham, Nov 15 '14 at 22:04
There are variables (often referred to as "environment variables") that Windows creates to help you find certain things. You can see a list of them by type `set` at a cmd prompt. So if you want to launch a program from the windows directory, but you aren't sure that windows directory is "c:\windows", you can use `start %windir%\system32\cmd.exe`. Similarly, there is USERPROFILE, so you can do echo %random% > %USERPROFILE%\logs\log.txt. — David Wohlferd, Nov 19 '14 at 08:27

if exist filename.ext (
    rem file exists
) else (
    rem file doesn't exist
)

Please also see this question.

If that is not possible to use relative path, use environment variables; because every thing can be different in your client station.
