windows - Is there a way to batch rename files to lowercase?

I need a way to rename all files in folders and subfolders to lowercase.

I'd like to know if there is a way to do that using only windows (XP or 7)

Answer

Go to the directory and run the following command:

for /f "Tokens=*" %f in ('dir /l/b/a-d') do (rename "%f" "%f")

---

Here is the break-down in case someone wants to modify/improve :

• for /f - For every line


• "Tokens=*" - Process each item in every line.



• %f in (...) - %f is your variable name for every item.


• dir - lists every file and subdirectory in a directory.


• /l - (parameter for dir) Uses lowercase.


• /b - (parameter for dir) Uses bare format, only the file/directory names, no size, no headers.


• /a-d - (parameter for dir) Do not list directories. (a stands for attribute, - stands for not and d stands for directory).


• rename "%f" "%f"- rename the file with its own name, which is actually lowercased by the dir command and /l combination.
