It is a single file to the underlying filesystem. Yes it reimplements a filesystem, I already said that in the comment you are replying to.

It isn’t a single file. There are multiple “hives” to the registry. There is at a minimum the SECURITY, SAM, SYSTEM and BCD “hives” that are all individual files on disk. Additionally, individual UWP apps can have their own isolated hive if need be.

Exactly like a NTFS drive can have mountpoints that are actually other drives, the Registry on disk is made by several files, at least: SAM SECURITY SYSTEM SOFTWARE NTUSER.DAT and since Vista BCD The whatever is called the Registry when virtually assembled together is accessed as if it was a filesystem on a single file, is not in itself a "file", it is something else, or if you prefer it seems like being a monolithic file but it is backed by a number of separated files.

It's far from being a single file. Registry is split to hives. Besides that, each hive is a bunch of files (actual hive, a pair of integrity logs - which was just one log file before Vista - and hell knows what else, some KTM-related stuff I presume): > dir /a C:\Windows\System32\config ... 29.07.2022 12:33 44 040 192 COMPONENTS 21.11.2010 10:21 1 024 COMPONENTS.LOG 29.07.2022 12:33 262 144 COMPONENTS.LOG1 14.07.2009 05:34 0 COMPONENTS.LOG2 29.07.2022 12:33 65 536 COMPONENTS{016888b9-6c6f-11de-8d1d001e0bcde3ec}.TM.blf 06.03.2021 21:44 524 288 COMPONENTS{016888b9-6c6f-11de-8d1d-001e0bcde3ec}.TMContainer00000000000000000001.regtrans-ms 29.07.2022 12:33 524 288 COMPONENTS{016888b9-6c6f-11de-8d1d-001e0bcde3ec}.TMContainer00000000000000000002.regtrans-ms
