Error with isp that opens explorer window.

[toffeemilkshake]

Hi all, I've been using AutoCAD for a while now but am only just beginning to learn how to use AutoLISP.

 

I have created a lisp that opens an explorer window showing the location of the currently open file:

 

(command "start" (strcat "explorer " (getvar "dwgprefix")))

 

My problem is that when I open certain files I receive an error dialog stating that:

"The path 'file path' does not exist or is not a directory."

 

This only occurs when the file path is quite long (over approx 40 characters).

Is there a way that I can fix this?

 

Thanks in advance

Is now really a good time to initiate your LISP skillset?

Hi toffeemilkshake,

 

Welcome to the forum

 

(command "start" (strcat "explorer " (getvar "dwgprefix")))

 

Seems to work fine. I just tested it with a path 142 characters long with no errors produced. I actually use a similar code myself which achieves the same thing

 

(startapp "explorer" (getvar "dwgprefix"))

 

The only time I come across erroe message

 

"The path 'file path' does not exist or is not a directory."

 

is when the directory does not exist

 

Are there any other parts to your routine?

Hi Jammie,

 

Thanks for the response.

 

There are no other parts within my routine so I have no idea what's wrong with it.

 

However I did try using your code and everything seems to work fine that way.

Your welcome toffeemilkshake,

 

I am not sure why your original code caused an error but glad I could be of some help
