how to remove a space (blank) at the end of a filename

Hi at all
i want to remove a space at end of a filenames by regular expression:
e.g
original:
sinatra, frank - my way .mp3
corrected:
sinatra, frank - my way.mp3

i have tried with the Replace method :
text to be replaced: (.+)<space>
replace with: \1
reg.exp.: tic

this works fine, but i want to leave this method active for many different files
if i do so, this method removed the last space in filename if there is no space at end of the file:
e.g.
original : sinatra, frank - my way.mp3
corrected : sinatra, frank - myway.mp3
that wrong - so, if there is no blank at the end of the filename, the filename should be leaved as it is (untouched).
regards
Bernd

You were nearly there. Try this instead:

text to be replaced: (.+)<space>$
replace with: \1
reg.exp.: tic

The $ is an anchor and means the end of the string. This means that the space must be at the end of the string.

If you have more than one space at the end, then use this instead:
text to be replaced: (.+?)<space>+$

The ? modifies the (.+) search to not be greedy, because normally the '.+' would match ALL the characters so that the subsequent <space> would not be found. It says "match as many characters as required, but leave enough to satisfy the rest of the regex that follows".

Good luck on your journey learning regular expressions!
