The current algorithm is as follows:

1. Take the value of the item key parameter or macro context.
2. Unquote the value if it contains quotation marks.
3. Resolve macros in the obtained value.
4. If the parameter was quoted or, after resolving macros, starts containing special characters, the parameter is enclosed in quotation marks.

I propose slightly modifying the logic in the last step. If the parameter cannot be enclosed in quotation marks due to syntax limitations, attempt to leave it unquoted. For example:

{$VMWARE.VM.FS.TRIGGER.USED:C:\}

Such changes should be implemented both on the server side and the frontend side.
