Total Commander

When I create CRC-checksum with TC, default filename editing selection is full path with extension
although it does not need to re-write the extension because it is determined by selecting CRC algorithm.

I think it is better to follow the same option setting for renaming as following :

'configuration > options > operation > select only the filename when renaming (not the extension)'

Just like in the copy/move dialog the F5 and F6 keys can be used here to toggle the selection between full path, only basename (filename without extension) and filename with extension.

Thank you for your useful tip !
