File Overwrite confirm/Backup settings

 

User often need to save output to files in replace operations. Sometimes the output file already exists, there are 2 related switches:

 

1. Create backup file before overwriting file or not.

 

2. Confirm with user before overwriting file or not.

 

User can turn on/off one or both of above swithes by open "Tools->Settings" menu, "File split/backup setting" frame.

 

 

User can also change the default backup file extension .bak to others, such as .new.

 

 

Note 1: If user's operation is to append to the file (>> or >>>), no backup confirm prompt and no backup file created.

 

Note 2: If the backup filename already exists, such as filename.bak, system will try to create a new backup file like filename.bak1 or filename.bak2 ..., until the file does not exist.
