# Winget-Install ## Mods The Mod feature allows you to run an additional script when installing, upgrading or uninstalling an app. Just put the script with the App ID followed by the "-install", "-upgrade" or "-uninstall" suffix to be considered. `AppID-install.ps1`, `AppID-upgrade.ps1` or `AppID-uninstall.ps1` and put this in the Mods directory > Example: > If you want to run a script just after uninstalling FileZilla, call your script like this: > `TimKosse.FileZilla.Client-uninstall.ps1` In the case of FileZilla it spawns a process "Un_A.exe" (NullSoft) as a graphical uninstallation and this we will have to wait for completion of before moving on to checking if the uninstallation suceeded or not.
