Error opening file: The extension source code is already being edited in the IDE

  
Hi

Here follows a tip. If you receive the error presented below, when trying to open a XIF in Integration Studio, follow these steps:
  1. Select Start / Run...
  2. Write %HOMEDRIVE%%HOMEPATH%\Local Settings\Temp\Integration Studio
    and press Enter, to open explorer in your folder C:\Documents and Settings\<USER>\Local Settings\Temp\Integration Studio
  3. Delete all *.lock files

Hi,
I have this problem but i can't solve it as you described.
I search every *.lock files in my computer, delete them and nothing.. i get the same error..

Do you know other way to solve the problem?

Hi,

You have to delete some temp files.
I guess it's C:/Windows/Temp folder files, i don´t remember that well.

Were you able to resolve this problem?  I'm having the same issue.
Hi,
To solve the problem I've had to implement a new extension. Otherwise could not solve.

Best regards

I came across this same issue. If anyone else has this what worked for me was deleting the locks and folders at 

"C:\Users\<your username>\AppData\Local\Temp\Integration Studio\". 

I know this is an old thread however it was the first thing that popped up when searching for the error so it might help anyone else trying to solve this bug.
