Hello,

as a part of a Java Client Backup Project I need a Regex command.
I want to exclude folders from the backup by Regex.

Excludes like that are working fine:
(?i).:/Program Files \(x86\)/.*
(?i).:/Program Files/.*

Now I search a Regex that excludes all folders of a drive except c:/Users/*

I tried (?i).:/!(Users)/.* but this ist not workink.
I also read a tutorial but didn't get informations about "all, but one not".

One more examble:
c:/Program Files/ >> match
c:/Program Files/folder1 >>match
c:/Windows/ >>match
c:/Users/ >> no match
c:/Users/User1 >> no match


Would be perfect if someone can help me.

Hi,

is there a reason why you need this strange "exclude anything but x" logic instead of simply telling the program to include x and nothing else?

Either way, an exclamation mark is no magical negation character. It's taken literally. The only way to exclude a certain expression would be through a negative lookahead:

c:/(?!Users)

But double negatives are just weird. Better use positive matches (or fix your application if it can't do that).

Hi Jacques1,

than you for your help.

The Backup solution just allows excludes with RegEx. Normaly you exclude c:/windows or c:/Temp.
Our Client strategy is that the users uses just c:/Users/xx folder. So we have to exclude all other folders. On the other site we don't want to force the user to backup the full user path. Users can choose all folders under c:/Users/____.

My final Regex are working fine:

(?i).:/(?!Users).*/.*
(?i).:/[^/]*\..*
(?i).:/Users/AppData/.*              
(?i).:/Users/Public/.*
