How can I rename some specific files in the directory to some other specific ones?
Have you tried the documentation and looking for “rename file”, first hit: RenameFile—Wolfram Documentation
I tried this one. But I want to apply it to multiple files. I tried to use multiple FOR loops (The Nested Loops), but I couldn’t manage it.
Maybe you can provide us with what you have tried, we can’t read your thoughts (yet)…
Please post it as code next time, not as an image.
Concatenation of strings it not done like that. The <> should be between strings. Please fix your syntax:
"DSC_" <> number <> ".tiff"
Thanks, still not working. But if you could give a general code for the following purpose, I’d appreciate.
“Taking 20 files and rename all of them in an order. For indtance 1.jpg, 2.jpg, 3.jpg, … , 20.jpg renaming to 21.jpg, 22.jpg, … , 40.jpg”
You could use for loops with indices, or similarly Do loops, or While structures or perhaps Table. But far easier is to use MapThread in this case:
fns = ToString[#] <> ".jpg" & /@ Range[1, 20]
newfns = ToString[#] <> ".jpg" & /@ Range[21, 40]
MapThread[RenameFile, {fns, newfns}]
This will apply the function RenameFile to each pair from the variables fns and newfns.
