Is there any difference when using Capital letters vs Small letters for folder or file name?

[smalltech]

Is naming a file/folder in capital or small letters making a differences?
What would it affect / bad effects if I use capital for file/folder names?

Are accessing all these path the same?
E:\data\recipe\chicken.txt
E:\data\recipe\CHICKEN.txt
E:\data\RECIPE\chicken.txt
E:\data\RECIPE\CHICKEN.txt
E:\DATA\recipe\chicken.txt
E:\data\recipe\Chicken.txt

I want to use capital letters for some files/folder names because it would make it stand out more among many folders, and I use capital for files/folders that are more important and frequently accessed.

Thanks

No problem at all.
The only problem you see is using spaces or special characters. Some applications won't like that.

If I name a folder/file as E:\data\RECIPE\CHICKEN.txt , when I access E:\data\recipe\chicken.txt , would it open the same file CHICKEN.txt ?

You can only have 1 'chicken.txt', whether it be caps or no caps.
