Retrieving the length of the beatmap from the .osu file?

I'm making a program that cleans the song folder from any unwanted beatmaps, empty folders and duplicates.
(If anyone is interested, tell me in the comments and I'll post a download here when it's done)
One of the filters I want to add is the min/max length of the song.
(since most short songs are trash and most long songs take up a lot of space)
Is there any information in the .osu files with which I can retrieve the length of the actual beatmap?
Or any other methodes to do so? (maybe a 3th party software/library?)
Thanks in advance,

All hit objects have a timestamp in milliseconds in the .osu file, so you could get the map's length by calculating the time between the first object and the last. The drawback is that this method disregards the length of the last object, so a 2:01 map with a three-second slider at the end will be seen as having a length of 1:58. You could also just get the length of the mp3 (probably with a 3rd party library), but that doesn't take the possibly unmapped intro and outro into account.
