You can use the evaluator in the definitions for file info tips and tiles mode to insert text returned by the evaluation.

Use the {= ... =} code to insert an evaluation expression. The expression between the {= and the =} markers can span multiple lines if needed. The return value of the expression is inserted into the info tip or tile.

You can also implement hide sections using the evaluator - use {!= ... =} to open the hide section with an evaluation expression. If the expression returns false, everything within the hide section will be hidden. Close the hide section with {!} as normal.

In this evaluation context, the following variables are available:

Variable Type Description

column name


All the column keywords are available as variables in this evaluation context.

Note that some keywords may use characters like a : that aren't valid in variable names - to access them, use the Val function.

Additionally, the keywords foldersize, foldercontents and infotip are also supported.



Returns the full name of the file the expression is being run for. This may be different from file which (as a column keyword), returns the value of the Name column (which e.g. may have file extensions hidden).



True if the expression is being run for a folder, false if it's being run for a file.

The return value should either be a str for an insertion, or a bool for a hide section.

  • If the expression is an insertion (using the {= ... =} code), the return value from the evaluation expression will be inserted into the info tip or tile at the point where the code appeared.
  • If the expression is for a hide section (using the {!= ... =} code), it should return true to show the contents of the hide section, or false to hide them.
