Where are Postman collections saved?

Question

It looks like Postman uses LevelDB. On Windows, I found my Postman DB located at:

%HOMEPATH%\AppData\Roaming\Postman\IndexedDB\

ps: %HOMEPATH% is path for C:\Users\xxxx\

also worth mentioning: %APPDATA% is a shortcut for C:\Users\xxxx\AppData\Roaming\

According to Piere F, macOS users can find it under:

~/Library/Application Support/Postman/IndexedDB

ps: Note ~ is path for /Users/userAccount/

According to David, Ubuntu users can find it under:

~/.config/Postman/IndexedDB
