The method has the following parameter:


An integer number that specifies the file’s new attributes. This parameter can accept one or a combination of constants listed in the following table (these constants are defined in the aqFileSystem object). To combine multiple values, use the bitwise OR operator.

The following code snippet makes a file read-only and hidden while keeping other attributes unchanged:

JavaScript, JScript

var finfo = aqFileSystem.GetFileInfo("C:\\MyFile.txt");
finfo.SetFileAttributes(finfo.Attributes | aqFileSystem.faReadOnly | aqFileSystem.faHidden);


finfo = aqFileSystem.GetFileInfo("C:\\MyFile.txt")
finfo.SetFileAttributes(finfo.Attributes | aqFileSystem.faReadOnly | aqFileSystem.faHidden)


Dim finfo
Set finfo = aqFileSystem.GetFileInfo("C:\\MyFile.txt")
finfo.SetFileAttributes finfo.Attributes Or aqFileSystem.faReadOnly Or aqFileSystem.faHidden


var finfo;
  finfo := aqFileSystem.GetFileInfo('C:\\MyFile.txt');
  finfo.SetFileAttributes(finfo.Attributes or aqFileSystem.faReadOnly or aqFileSystem.faHidden);

C++Script, C#Script

var finfo = aqFileSystem["GetFileInfo"]("C:\\MyFile.txt");
finfo["SetFileAttributes"](finfo["Attributes"] | aqFileSystem["faReadOnly"] | aqFileSystem["faHidden"]);
