InDeep File List Maker is a freeware tool that can create a list of the contents of your folder and use the lists to search for files.
The program is portable, so you can take it with you on a USB memory stick if you wish. Extract the files from the archive and run FLM.exe to use the program. InDeep File List Maker has a nice GUI with minimal elements.
File List Maker supports drag and drop. When you drop a folder on the program interface, the program automatically creates the list, ie the preview is displayed immediately.
In the Depth menu you can choose whether to include subfolders or empty folders in the list. You can choose to add subfolders with different levels of 1, 2, 3 or all folders.
