Topic: Help: add extension to files with lisp

[PM]

Hi. I  have a big list of *.sld files. The problem is that missing the extension .sld. I have only the name of the file.Is it possible to put all this files in a folder and add the extension .sld with a lisp file without change the name of the files ?

Thanks

Why does this have to be done with Lisp?

This could be fairly simple for you to do:
1. Create folder.
2. Sort your directory by filetype.
3. drag those files into the folder.
4. use a .bat file to rename the files in that directory.

Code - Bash: [Select]

1. rename * *.sld

Like john use old fashioned DOS, lower left cnr of windows not cad, type cmd, ok tricky bit

CD \whereis\my slides files       replace with correct path
rename * *.sld        hOPEFULLY ALL DONE

BIGAL little time saver with cmd. navigate to the folder you want to run the command in with windows explorer. Then type cmd in the address bar the command prompt will start in that folder location.

I use PowerToys you can select files you want to rename directly form windows explorer

Tho I mainly use PowerToys for Fancy zones and always on top.

Use a .BAT file.
1. Navigate to the folder.
2. Create a new text file and call it "rename.bat".
3. Edit the file and place the code in it.

Code: [Select]

@echo off
rename * *.sld4. Save and close the file.
5. Double click the "rename.bat" file.
