Renaming Multiple Rar Files
This guide describes the use of the WinRAR command-line tools (v5.01) for compressing and uncompressing files in a directory and their use in batch files (for IZArc and 7-zip, see this post). This guide is an extension of a previous post, Automate Zipping Tasks using the Command-line Interface that explained the use of the command-line tools for two free compression utilities, IZArc and 7-Zip. The information in this guide was tested on a Windows PC running Vista.

WinRAR is a popular and powerful archive manager that can be used from the command-line or with scripting languages such as batch files. It includes two command-line tools, rar.exe and unrar.exe, where rar.exe compresses and unrar.exe uncompresses files. Both are located in the “C:Program FilesWinRAR” folder in the installable version. Although WinRAR is shareware, it can be used on a trial basis for 40 days. Using WinRAR’s command-line tools is similar to those for IZArc and 7-Zip. The syntax for using the WinRAR executables is:
To get a listing of the options for the rar and unrar commands, open a command window, cd to the WinRAR directory, and type rar or unrar and then press enter (rar /? or rar help may also be used, use rar >rar_cmds.txt or unrar >unrar_cmds.txt to print the command options to a file). For more detailed information, open the rar.txt file in the WinRAR directory which contains the RAR console version user’s manual.
Examples to compress a folder:
creates archive yourfiles.rar and compresses all .txt files in the current folder
creates archive yourfiles.rar in C:yourfolder and compresses all .txt files in the current folder and its subfolders
List all file names from a specific folder in worksheet with kutools for Excel. If there are multiple files that you want to rename, first, you can list the old file names in a column of worksheet, and then enter the new filenames that you want to replace with. Method 2: Rename Multiple Files using Windows 10 File Explorer To rename multiple files in bulk on Windows 10 PC, follow these steps: Note: This method is applicable if you want the same file name structure for every file. Open the File Explorer either from the taskbar or the desktop. Open the folder whose files you want to rename.
creates archive yourfiles.rar in C:yourfolder and compresses all .txt files in otherfolder and its subfolders
creates archive yourfiles.rar and compresses all files in the current folder, but doesn’t include subfolders (note lack of extension; WinRAR will use the default extension .rar)
“a” command. Adds to the archive
“-r” switch. Recurses subfolders
Examples to uncompress a folder:
extracts all *.gif files from yourfile.rar to c:extractfolder (trailing backslash required) and restores the folder structure
extracts all files in c:yourfile.rar to the current folder (folder structure ignored)
“x” command. Extracts with full paths
“e” command. Extracts and ignores paths
Compression example using Multiple Switches:
Bulk File Rename
compresses all new or updated files from c:test and its subfolders to e_archive.rar, deletes the files after they are added to the archive, and excludes any files with a “bat” extension,
“a” command adds to the archive
“-r” switch. Recurses subfolders
“-ep” switch. Adds files to the archive without including the path information. Multiple can exist in the archive with the same name.
“-u” switch. Equivalent to the “u” command when combined with the “a” command. Adds new files and updates older versions of the files already in the archive
“-df” switch. Deletes files after they are moved to the archive
“-x” switch. Excludes the specified file(s) from the operation
Basic rules for WinRAR:
- When files or listfiles are not specified, all files in the current folder are processed
- When specifying all files in a folder, yourfolder or yourfolder*.* are equivalent
- Folder structures are automatically saved in archives (but not automatically extracted)
- WinRAR uses the .rar extension by default, but that can be overridden by specifying the zip extension in the archive name
- Switches and commands are not case sensitive and can be written in either upper or lower case
Another point is that WinRAR doesn’t appear to install to the Windows path environment variable, so it must be specified either at a command prompt, set permanently in the environment variable settings, or specified in a batch file (WinRAR v3.71.0.0 was used for this guide and that may not be the case for all versions).
To set the Windows path environment variable temporarily at a command prompt or in a batch file, use the following command:
To set it permanently in the Windows path for your PC:
start–>Control Panel–>System–>Advanced system settings–>Advanced Tab–>Environment Variables–>System Variables–>Path–>Edit. Add the path ;C:Program FilesWinRAR; to the end (don’t forget the single semicolons at the beginning and end). Hit OK three times.
Using WinRAR in Batch Files:
Two batch file examples are provided below, The uncompress_rar.bat file decompresses all .rar files from a folder and places the extracted files into another directory.
The compress_rar_rev2.bat file provides the following compression options for a user specified directory. Option 4 is the most commonly used structure and the most appropriate option in most cases:
- Compress files in dir individually (no subdirs)
- Compress files in dir and subdirs individually – no paths
- Compress all files in dir into a single archive (no subdirs)
- Compress all files in dir and subdirs into a single archive
- Compress all files in dir and subdirs into a single archive – no paths
Be sure to change the extension(s) to .bat before using either file and edit the folder paths as required. Both of the following batch files temporarily set the Windows path environment variable for the WinRAR application folder when executed.

When you have many files in a folder, renaming these files individually can take a lot of time. You do not have to rename files one-by-one. Following these directions will show you how to rename multiple files at once.
1. Select files you want to rename (you can press Ctrl+A to select all files or Ctrl+Left mouse to select files of your choice)
2. Hit F2 button on your keyboard.
You can also right click and select Rename from the context menu.
3. Rename your first file and hit Enter. The following files will be renamed right after that with an extra number at the end.
