Change Case

Use this dialog box to change the letter case of selected file and directory names.

Change Case to

Select one of the following case types for names.

Name Case Type	From	To
Lower case	mY docuMENT.tXt	my document.txt
Upper case	mY docuMENT.tXt	MY DOCUMENT.TXT
Partially mixed case (name in mixed, extension in lower)	mY docuMENT.tXt	My Document.txt
Mixed case	mY docuMENT.tXt	My Document.Txt

Change

Select which parts of file names should be changed.

Whole filename: the case type is applied to the name and the extension.
Only name: only the part before the last dot is changed; the extension keeps its case.
Only extension: only the part after the last dot is changed; the name keeps its case. Names without an extension are left unchanged.

With Only name or Only extension, the partially mixed case type works like mixed case for the name and like lower case for the extension.

Include subdirectories

When checked, the operation includes files and directories contained within selected directories.
