What generates the spaces into file names? I rarely if ever encounter spaces anymore in files names inside epubs.

Assuming this is a common problem, you can use a file base name and automagically number files in BookBrowser around that base which I commonly use for Chapters leaving only front matter and end matter to hand edit the names for but that changes the root name of the file.

Using Regex Rename is probably the easiest way to preserve parts of existing file names.

Have you tried using (\s) at the Regular Expression and _ as the Replacement?

Seems to work for me.
