#rb Patrick.Laflamme #jira UE-145721 #rnx #preflight 622f0358752729a2ad448e16 - The problem we have is if a p4 depot path is used when requesting filestates (to see if the file exists in p4 for example) it will be treated as a networkpath due to it starting with // so calling the filesystem to check if it is a directory or not can get very expensive. - Other operations just check the end of the path for '/' or '\' which is what this operation used to do, but that was changed at some point to check the file system, presumably to fix another problem and as we don't really know how 3rd party code is using this system we cannot just change the behavior without risking breaking existing code bases. - This fix allows the caller to opt in to the old behavior of just checking the end of the path to determine if it is a directory or not. - This fix is not very good, future work for a better fix will be tracked in the attached jira.
