1.) Examples of renaming files with the REN command!
Example 1: Change all file extension from log to txt
rename *.log *.txt
We can rename, change the extension of files in batch with the REN or RENAME command . For example, suppose you have a number of files with a .jpeg extension and you want to rename them to .jpg. You can do this with the following command ren *.jpeg *.jpg, all files in the current directory will be changed from *.jpeg to *.jpg
Example 2: Change file extension also in the subdirectory
If you want to rename files recursively in all subfolders from one extension to another, you can use the forfiles command in combination with rename or ren .
The following command would completely remove the extension for the specified file types.
After executing the above command, file-1.doc will be in the d:\My Documents\file-2.doc folder
2.) Why use REN command to rename files!
The REN or RENAME command in Windows is used to rename files or directories. This command has several practical use cases:
Organize files: You can use the REN command to rename files in folders or on your desktop to keep them more logical and organized.
Versioning: If you create and constantly update files, you can use the REN command to give older versions a clear naming scheme, such as: E.g. "Document_v1.doc", "Document_v2.doc", etc.
Backup copies: When creating backup copies of files, you can use the REN command to create backup copies with timestamps or version numbers.
Elimination of spaces and special characters: If files contain unwanted spaces or special characters in the name, you can use the REN command to remove them to avoid problems accessing these files.
Filename change for scripts: When writing scripts or automations, you can use the REN command to change filenames according to the needs of the script.
Bulk Rename: You can also use the REN command to rename a large number of files at once using wildcards or patterns.
ren *.txt _new_*.txt
This command would rename all text files in the current directory by adding "_new_" before the original filename.
The REN command provides an easy way to change file names in the Windows Command Prompt and can be useful in various situations, especially when you manage many files or perform automated tasks.
Changing the screen buffer size for MS Windows OR Command Prompt output is very convenient and easy on Desktops and MS Server OS With larger / longer text
