I love Q-Dir. Good for you. Microsoft should have done that a long time ago.
In the 1980's I had a program that allowed me to
(1) Select files by size, date, extension, or name wildcard.
(2) Make find/replace changes on the file names or file attributes for all selected files.
For example, find all JPG files in date range Jan 1-Jan 5, then change the names to "New Year Trip###"
TO>Microsoft should have done that a long time ago.
Nothing is perfect,
everything can be improved
And the improved can be improved;)
Will add in one of the next Q-Dir
