I am deleting a file that is not under version control, all Safe Delete options are turned on: I get "Usages detected": "file serverVersion.properties.xml has 4 usages that are not safe to delete. Of those 0 usages are in strings, comments, or non-Java files. ", choose "Ignore" option: on the next step IDEA suggests to checkout files form Perforce that have the usages (e.g. one of the files is build.xml) It will modify the files during the file delete, so should not check them out. Next, I get P4: auto-remove files confirm Why? the file is not added to Perforce and is drown in brown color. On Yes, I get: Error:C:/Work/perforce/TeamServer/BuildServer/server-model/src/serverVersion.properties.xml - file(s) not on client.
