Windows 10: What characters are not permitted in a file name

I accidentally saved a file that contained an = in the file name. I was surprised that File Explorer didn't reject it. I then tried the characters ! and ? ! was OK, ? was rejected. I'd like to know if there are other permitted characters. What is the rationale for what is rejected? Is there a Windows available 11? that expands the definition of what is permitted?Thanks.SweetTasha

Text Files Register 0 Bytes even with 90K Characters, Cannot E-mail

Sometimes it's as simple of clicking the Name at the top of the column in Details view then click it again to get the list refreshed. Also usually works to close and open File Explorer and navigate to the folder that contains the file. Keep in mind that a folder cannot contain 2 files of the exact same name, one has to be at least one character different. And possible to open a file in the program used to create it, see if there's actually anything in it. Also possible to open that program then File, Open and see it's listed.

 

Searching file names using wild characters

In searching File Explorer (Win10) the wild character "?" doesn't seem to work when searching for a file name. e.g. "?E1" doesn't produce a list of files having E1 as 2nd & 3rd character in file names. Used to work beautifully in Win 7.
