ReNamer:Validation

Validation is a process which tries to prevent common renaming problems by analyzing the list of files and target destinations. A warning message is given when possible problems are discovered. Users should generally eliminate all warnings prior to renaming, otherwise items may fail to rename.

Here is a list of reasons for a warning during validation process:

1. There are duplicated destination paths
2. New path contains forbidden characters
3. New path is already taken by an existing file
4. New path exceeds maximum length

By default, automatic validation is enabled during the preview process. This behavior can be changed from within the settings.

Note: Validation may require significant amount of time when processing large amount of files.
