However, you can use the remarkably similar looking "Modifier Letter Colon" character (Unicode U+A789) in filenames/folders:
Quote:
(not a colon)
On a similar note, you can put forward slashes in your filenames and folder names too, using the "Division Slash" character (Unicode U+2215):
Quote:
(not a slash)
For quick use, I set up an AutoHotkey script so that typing ;;; results in the modifier letter colon and typing //; results in the division slash:
Code:
:*:;;;::{U+A789}
:*://;::{U+2215}
Anyways, happy organizing!
