"Rename file" command
This command allows to rename a file or folder under the cursor and is accessible both in file management and in archive management modes. Renaming files inside of archives is supported for RAR and ZIP formats. To run this command use either Commands menu or F2 keyboard shortcut.
Rename command has some restrictions when working with multivolume archives Only those files which are contained in the current volume can be renamed. If you wish to rename files in volumes, you need to disable "Merge volume contents" option in the File list settings dialog and open the volume containing required files.
Be careful when choosing a new file name. If it includes characters, which are not supported by file system, you may have problems with extracting the renamed file afterwards. In such situation just rename it again to something more usable.
