Scan your files and folders to get their properties: size of files and folders, etc. You can easily export the result in a text file (.txt) that can be later imported in another program.You can import the result in a spreadsheet like Excel. This will allow you to do some search but also to have a clean ordered listing of your files. Which is nice because sometimes you don’t know what you are looking for but you still want to find it.
You can import the result in a database like Access. This can be useful because TinyScan gives you a flat table that you can later query with SQL. So it allows you to query your file system like a database.
