KAS Project File Clean-up

If the KAS project file size is unexpectedly too large, it is likely that there are some legacy or possibly corrupt HMI project files included in the project.

To clean-up unnecessary and/or corrupt files, do the following:

1. Close the IDE.
2. Copy the .kas project file to a backup file.  Just in case you accidently delete a needed file.
3. Open the .kas project file with 7-Zip.  For example, right click on the project file, select 7-Zip->Open Archive
   1. At the top level, if there are 2 folders named Controller, one of them will have a space at the end. Delete this one.
   2. Navigate to the HMI\KVB 2 directory.  Check the sub-directories and underlying files.  Delete any sub-directory that is not part of your KAS project.
4. Remove the Kollmorgen Project folder for your user account:  %LOCALAPPDATA%\Kollmorgen\KAS\Project
   • This step is necessary to prevent new projects from inheriting all files and folders in the Project folder.
   • The following procedure will remove the entire Project folder. Note that the "Controller " folder (with a space at the end) cannot be removed by Windows Explorer.
   1. Open a Command Prompt window.
   2. Enter the following command.
   • rmdir %LOCALAPPDATA%\Kollmorgen\KAS\Project /s /q
5. Open the .kas project file with the IDE.
6. Re-compile to confirm there are no missing files and save the project file.

For example, the following 12MByte project only has one HMI device:

And the .kas project file has 5x HMI projects:

Notice the file names have strange characters.  The IDE was unable to automatically clean-up these files:

Deleting the legacy and/or corrupt HMI files, leaves behind the single HMI project directory used by the KAS project:

The resulting cleaned-up KAS project file was reduced from 12 Mbytes to 260 kbyte.

And likewise, deleting the %LOCALAPPDATA%\Kollmorgen\KAS\Project will prevent the files from being included in future projects:
