Trouble with GUI generated source exclude filter

[ts678]

Edit: I think if they prepended the entered pattern with .* and appended [^\\]* (instead of .*[^\] it would work - if the intent was to ensure it is in the filename portion

Agree.

@ts678

I suspect the bug is from suffix: '.*[^!]]', where a Negative Character Group: [^] means to not match something ending with the separator that indicates a directory, according to Duplicati Syntax documentation.

Character Escapes start with backslash, so Windows directory separator backslash needs its own backslash whereas I have a suspicion that this bug would not happen on Linux. A forward slash is not special to an RE, however a backslash before a non-special character just gives the character, so “!” in source “should” work.

and one additional note on the above comment is that the ! in source code turns into directory separator.
