Need to view files as crude sketches in a folder

Hello, I’ve worked with FreeCAD (only) for 5 years now, designed and printed over a 100 of parts for about 15 various projects. That is partially my problem. I failed to categorize and separate the project files by folder. Now I am looking for a specific drawing and cannot find it by name or trial-error using FreeCAD (too laborious). So, I am looking for a way (a program) that would display crude sketches of my drawings, files *.FCStd, as “picture icons” in a folder (similar to looking at my photo album). Anyone knows about such software?
Thanks in advance.
