check spelling of folder names

hi
is it possible to check spelling in folder names?

Not directly but you can save a list of folders to a file. Then open the file in Excel (or free equivalent) duplicate the list of files into a new column and spell check the copy. Save as a csv file with original folder names in column 1 and corrected names in column 2 and load the folders into Advanced Renamer using Import -> Files from CSV...

To save the folder list to a text file open a command prompt in the directory containing the folders and run the command dir /ad >folders.txt
