Q: Can I rename bulk of files, like 15000+, via import rename list?

A: Yes, the latest KR support import rename list with buffer.
When you import bulk of rename file list, usually it will take a very long time to load into program.
KR let you set how many buffer lines you want to load in [options] menu. (Default amount is 128)
When you press [Rename], KR will renames all of rename file list, not only files show on the file list view.
Note:
1. If you set buffer lines to 0, KR will load all of rename file list.
2. If you change rename action after import, it will only effect files that show on
the file list view.
