So this is my collection files http://puu.sh/h2mes/ea84f8bc38.zip
I've compiled beatmap which was used in the osu! world cups and some from tournament,
and also a lot of unranked songs that I like to use in multiplayers

Cara cipta backup koleksi
Step 1: Muat turun > Extract osu!CollectionEditor.zip (mana2 saja) > Open osu!CollectionEditor.exe

Step 2: File > open collection > osu!collection > Browse dalam fail osu! > collection.db
step 2b

Inilah lokasi fail saya dalam windows XP raksasa C:\Documents and Settings\L\Local Settings\Application Data\osu!
Windows 7,8,8.1,10, kalau nak cari lokasi > right click shortcut > open file location (malas nak cari)
Just Like This


Step 3: Tools > Load beatmaps > fail osu!
3b


Jika anda tak nak kongsi sebahagian koleksi sahaja, anda boleh pakai split collection, untuk .osdb fail masing2
Tools > Split collection into individual files

Under osu! collection logs folder, you can find splittedcollection_X (X = nombor kali pertama,kedua dan seterusnya)
folder 1
folder 2

Under this folder, you will find the subcategory of all your favorite folders
satu fail = satu fail koleksi
in-game menu

Step 4: Export as .osdb
#Anda perlu ada semua beatmap dalam collection.db sebelum anda belum eksport dalam .osdb format

Caranya,Tools > Export collection > Save As

Anda nak apa2 nama pun boleh

Cara load backup koleksi
Step I: Buka fail .osdb
File > Open Collection > Shared Collection > From File

pilih saja mana2 .osdb yang anda mahu
Ini ialah fail yang digunakan untuk berkongsi ataupun backup


Step II: Sama dengan step 3
Tools > Load beatmaps > fail osu!
Gambar 2

Kalau ada beatmap yang tidak ada dalam fail song, notis You're missing xxx maps from collection akan terkeluar

Untuk download beatmap yang tiada dalam fail song
Tools > Generate list of...> Missing Maps

Isi apa2 nama saja, lepas tu buka .html fail itu
html akan tunjukkan semua map yang tiada dengan beatmap link
List Panjang


Step III: Save osu!collection and replace collection.db
File > Save osu!collection

Gambar 3

Jika anda tidak semua map, map yang ada akan ditunjuk dalam collection
Map Sempurna
Map Sebahagian, tiebreaker tidak terjumpa

Aduhai, Kenapa nak convert ke format .osdb?
Inilah Alasan saya
Joining collections(load collection first then join as much as you want)
Caranya sama dengan Cara load backup koleksi tetapi kena tambah lagi satu step sebelum Step II

Step 1.5, File > Open Collection > osu! collection

For demonstration, I've created this collection which is my current collection.db in my osu!
Sebagai contoh, saya telah ciptakan fail osumania, koleksi ini sekarang di collection.db dalam osu!
So I just go ahead and choose the collection.db to merge
Tools > Join collection
Remember to change the file type to osu!Collection for .db files
I think osu!collection database is for .osdb file but I think it 100% works since you can load the beatmaps and check before you create a new collection.db
Now do step II again,
Step II:
Tools > Load beatmaps > fail osu!
Gambar 2

Do this to check if your collection has been added
Tools > Generate list of...> Missing Maps
You will see this new collection added if you are successful, if you don't just close the program and retry again

and finally we can go to step III and use the new collection.db
Step III: Save osu!collection and replace collection.db
File > Save osu!collection
I feel stupid doing all this to add just 3 maps
