Date calculation
Question / Problem
How does TreeSize calculate dates for files and folders?
Answer / Solution
For files, the value of the file itself is taken. For folders, the highest value of all child elements and optionally (this setting is enabled by default) the value of the folder itself is used.
If you do not want TreeSize to use the value of the folder itself, you can enable the option "Include only file dates in folder date calculation" in the "General" options.
