I kept my demo files for longer time because of etf2l. Maybe someone does the same and this will help him with getting rid of unnecessary demo files after season or two.

Some of those that use valve's demo support have folders full of demo files that we don't even have any bookmark on. So I made this little program that can remove demo files that don't have any event recorded on them, move demo files that have some event recorded on them and also can read the .json files.

First the screenshots:

And here are the downloads:

It's open source so you can read how bad my code is, you don't have to tell me, I know it!
Ideas how to improve the program and questions are welcomed.

Edit: Just updated to version 1.1.0
Changelog:
Redesigned the application a little
Readability is little better, but you have to have "Newtonsoft.Json.dll" in the same folder as "TF2 Demo Tool.exe"
Minor text changes

Edit: Updated to version 2.0.0
Changelog:
Added option to save default folders (folder with demo files and "move-to folder") so you won't have to choose them every time

Minor text changes

Minor text changes

well, I can't play demo's only from 11.3 to 17.3, others are ok, just these and i know i was editing them before (12.3.2016)) so they are not broken.

If someone is backuping the .vpk's and stuff like that we could ask them to upload it somewhere and then use them, its probably just the maps becouse they updated them when mm got out.

So, someone, please, upload old versions of valve mm maps ( process, badlands, granary, foundry, gullywash, snakewater, lakeside)

As for me, I need these maps:

cp_process_final from: 11.3.2016 + 17.3.2016
cp_snakewater_final1 from: 17.3.2016
