Windows 10: Batch change of file extensions - Windows 10

I have recovered 900 photos, these now have the .chk file extension. I can change individual files to .jpg and then the image is fine. I now need to convert all 900 in one folder. Hopefully there is a method to run a 'batch' conversion. Grateful for any advice please.

Renaming Multiple File Extensions With a Batch File

Hello,

Pretty self explanatory question, but not turning up the results I need. If I use a command line window to change a bunch of file types, I can do the following:

CD LocalDirectory\Is\Located\Here

REN *.jpg *.tif

This changes every file that has a JPG extension to a TIF. I'm trying to replicate the same thing, but do it in a batch file, but I keep throwing an error that says "The system cannot find the file specified." I'm not sure if the syntax has to be different
as a batch file as opposed to just typing it into Windows Command Line itself. Here is the code I have now:

Code:

title Image File Extension ChangeECHO Finding directory, please wait.CD LocalDirectory\Is\Located\HereECHO Renaming files, please wait.

ren *.jpg *.tif

pause

Thank you for the help!

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Batch Files Knowledge Base

Don't use batch files very much but one I find useful is for creating a list of files in a directory.
Just copy the text below into Notepad and save as Filelist.bat

dir /a /-p /o:gen >filelist.txt

When you run it from a folder it will create a Filelist.txt file,in the same folder, that lists all the files in that folder.Useful when you are too lazy to type all the files out yourself.
