batch filename editing

Now using XP pro.
What is the handiest way to edit filenames in batches? For instance, I have a lot of .JPG files that I need to change to .jpg.

There should be no reason that the file type MUST be lower case.
But there are many programs that can rename files.
Do a google search on “Rename files” and you will find all kinds.

Thank you, Dave: I was hoping for a recommendation.
The webserver I use can’t digest upper-case in filenames.

Erm – why would you want to change .JPG to .jpg? Although Windows remembers how filenames are created/entered and displays them that way, it doesn’t distinguish between upper case and lower case when handling files.

You can use the command prompt window or a batch file to rename all files of a certain type in a folder. The command for renaming would be:

REN “C:Some FolderPicture Folder*.JPG” *.jpg

where C:Some FolderPicture Folder is the folder containing the files.

Once again, Thank you, Hans.
The webserver I use can’t, or won’t, digest upper-case anywhere in filenames.
So the DOS batch-file approach is still the best way to go – OK.
It would be nice, though, if REN would accept a /S and work through all sub-directories.

There are (free) utilities that may ease the job:

RNameIt from Son Of Spy WinUtils 4.
1-4a-rename. Freeware file renamer for Windows 95/98/2000/XP.

Oh yeah, I also have that jpg v. JPG problem with MY web host, as I would think most people do. In addition to Hans’ suggestions, Alan Miller made this recommendation in post 582,336.

On this same thread, is there an easy way to rename folders (just folders not files) via bat files?
I have a program that has two separate functions (applications).
Unfortunately, they all want claim to the registry and path despite conflicting dlls.

I noticed that by creating a copy of DIR A after Prog1 installs ,and then allowing Prog2 to install over the original DIR,
that I can regain functionality by just renaming the applicable Dir.

Sequence:
Install Prog1 create a copy of DIRA..called “Copy of DIRA”
result: Prog1 works
Install Prog2 allow it to install and register .dlls to DIRA
result: Prog2 works Prog1 doesn’t
rename DIRA to DIR1 rename Copy of DIRA to DIRA
result: Prog1 works again

I realize it’s just a workaround, but if I could automate it by 2 separate batch files, it could be run by the users.

Any ideas?

The DOS command REN or RENAME can be used to rename folders as well as files in a batch file.
