Example: Flags: isreadme Remarks If a file already exists on the user's system, it by default will be replaced according to the following rules: Grants 'Read & Execute' permission, which allows the specified user/group to read and execute the file. Grants 'Modify' permission, which allows the specified user/group to read, execute, modify, and delete the file. Use sparingly generally, modify is sufficient. The following access types are supported for the section: Grants 'Full Control' permission, which is the same as modify (see below), but additionally allows the specified user/group to take ownership of the file and change its permissions. This parameter can include one or more space separated values in the format. The specified permissions are set regardless of whether the file existed prior to installation. Never change the ACLs on shared system files, otherwise you can open up security holes on your users' systems. This parameter should only be used on files private to your application. In the event these conditions are not met, no error message will be displayed, and the permissions will not be set. It is not recommended that you use this parameter if you aren't familiar with ACLs or why you would need to change them, because misusing it could negatively impact system security.ДЇor this parameter to have an effect the file must be located on a partition that supports ACLs (such as NTFS), and the current user must be able to change the permissions on the file. If this parameter is not specified, Setup does not assign any special attributes to the file.Д®xample: Attribs: hidden system Specifies additional permissions to grant in the file's ACL (access control list). This can include one or more of the following: readonly, hidden, system, notcontentindexed.

(The previous default was CopyMode: normal.) Specifies additional attributes for the file. This parameter was deprecated and replaced by flags in Inno Setup 3.0.5: CopyMode: normal -> Flags: promptifolder CopyMode: alwaysskipifsameorolder -> no flags CopyMode: onlyifdoesntexist -> Flags: onlyifdoesntexist CopyMode: alwaysoverwrite -> Flags: ignoreversion CopyMode: dontcopy -> Flags: dontcopy What was CopyMode: alwaysskipifsameorolder is now the default behavior. Example: ExternalSize: 1048576 Flags: external You should not use this parameter in any new scripts. 'foo bar' will exclude both 'foo bar' and 'subdir foo bar'. On the other hand, 'foo' will exclude any file named 'foo' anywhere in the tree. Thus ' foo' will only exclude a file named 'foo' at the base of the tree. If a pattern starts with a backslash (' ') it is matched against the start of a path name, otherwise it is matched against the end of a path name. Will not exclude files with names less than five characters long. Also, question marks always match exactly one character, thus '?'

Dots in the pattern are always significant, thus '*.*' will not exclude a file with no extension (instead, use just '*'). Note that unlike the Source parameter, a simple Unix-style pattern matching routine is used for Excludes. Patterns may include wildcard characters ('*' and '?' This parameter cannot be combined with the external flag. I need help using the FileExists function in Inno Setup.Д®xample: DestName: 'MYPROG2.EXE' Specifies a list of patterns to exclude, separated by commas.
