Writing resources to target file
When resources are written to the target file, the source file is copied and all resources are replaced by the input translations. However, you can activate the Keep original resources radio button, so that the previous resources are not replaced but the new ones are added. In this case, the target file will contain all resources in both languages (the original and the target language version).
If the target file is the same as the source file, the original resources are always retained, regardless of the setting for this option.
The Keep NEUTRAL resources option replaces only those resources that do not have a language ID. Resources lacking a language ID (NEUTRAL) are retained. If resources that should not be translated, e.g., cursors or icons, are marked as NEUTRAL in a source file, you can use this option to create a multilingual application, in which the target file does not contain multiple instances of such resources.
