Are there any limitation about the number of sub-folders we can have in sharepoint document library

Question

I got a question from our customer about how many sub-folders levels we can have inside sharepoint online document library. now based on my knowledge there is not any limit. now i am not discussing if we should have many levels of sub-folders, but my question if we really have a limit.

Based on my test i was able to create 7 levels of sub-folders, and i uploaded a word document inside the last level, and the word document URL is consists of 264 characters which seems it is also acceptable.

so my question is if there are a limitation about the number of sub-folders we can have inside SharePoint online document library ? or limitation of the url length (where the url length will be increasing as we add more sub-folders)?

Thanks

See SharePoint Online Limits:

• A list can have up to 30 million items and a library can have up to 30 million files and folders.
• SharePoint Online supports URL paths up to 400 characters (SharePoint Server OnPremise only 260)
• You have a list view limit of 5000 items (might get changed, they are working on that), which means that you should not have 5000 or more subfolders within a single folder.
