	~~Some time soon~~, kJams will switch to ~~an optional~~ "Subscription Model". ~~I say~~ optional because there will be no requirement for existing users to switch, you will be free to continue using your perpetual license, which will never be revoked. However, ~~there will come a time when~~ new ~~updates~~ will ~~no longer~~ be ~~available to existing perpetual licenses~~, ~~except for~~ critical bug fixes.		Within the next couple of months, kJams will switch to a "Subscription Model". It is optional because there will be no requirement for existing users to switch, you will be free to continue using your perpetual license, which will never be revoked. However, no new development will be done on the older editions, only critical bug fixes. I will continue to make updates for at least 6 months.

	~~Note this~~ is not related to licensing ~~at this time~~. ie: if you subscribe, it won't cause kJams to have a license, and if you unsubscribe, it won't remove your existing perpetual license. ~~If you just purchased kJams, feel free to wait a year before "subscribing" since in effect you just paid for a full year up front~~. ~~Of course, feel free~~ to ~~subscribe anyway~~, to ~~"support the cause" ;-~~) ~~In the future it'll be built in, and WILL manage your license~~.		Currently the Patreon subscription is not related to licensing. ie: if you subscribe to Patreon, it won't cause kJams to have a license, and if you unsubscribe, it won't remove your existing perpetual license.

			The new system WILL manage your license. The new editions will be HomeParty (equivalent to Lite + Burning), and NightClub (equivalent to 2).

	* Lite: $6 per month: Includes 1 hour of ETS		* Lite: HomeParty is $8 per month: Includes 1 hour of ETS
	* Pro/2: $12 per month: Includes 2 hours of ETS		* Pro/2: NightClub is $16 per month: Includes 2 hours of ETS

	This actually works out okay ~~for Pro users~~: If you use ~~kJams Pro/2~~ only 3 months per year, then it only costs you $36 per year. Want to use it just over one weekend? That's $12. Next time you subscribe, you get ALL the latest updates. If you use it full time, then the yearly cost is about the same as a yearly upgrade. Another example: for a Lite user who only throws a Christmas and a New Year's party, you only pay $6!

Remove Duplicate Index Entries

add Remove Duplicate Index Entries help page

New page

= Remove Duplicate Index Entries =

This feature is available in the Qt (64-bit) edition of kJams under '''Advanced → Special → Remove Duplicate Index Entries…'''.

== What is an "index entry"? ==

Each song in your kJams '''Library''' has a unique '''song ID''' (index entry). That is separate from a '''playlist item''' (a reference to a song in a rotation list, custom playlist, singer list, etc.).

Sometimes the same physical media file is imported or added more than once, creating multiple library index entries (different song IDs) that all point at the '''same file on disk'''. This command finds those duplicates and consolidates them.

== What the command does ==

# Computes a '''Path Hash''' for each library song that has a resolvable local media path (ZIP, then video, then audio — same priority kJams uses elsewhere).
# Groups songs with the same hash (same resolved file path).
# Within each group, keeps the entry with the '''lowest song ID''' as the canonical copy.
# '''Updates playlists''': any playlist reference to a removed song ID is changed to point at the canonical song ID. If the playlist already contains the canonical entry, the duplicate playlist reference is removed instead.
# '''Deletes''' the extra library index entries (and their library playlist rows). Your media file on disk is not deleted by this operation (only cache/temp files associated with the removed entries may be cleared, same as normal Remove from Library).

== What is skipped ==

Songs with '''no resolvable local file path''' are skipped — for example some streaming entries, some music-store entries without a local file, or songs whose files are missing. They are not hashed and are never merged or deleted by this command.

== What this does '''not''' detect ==

* The same audio on disk via '''different paths''' (aliases, copies in different folders, hard links with different path strings).
* Duplicates that share metadata (name/artist/album) but point at '''different files'''.
* Duplicates defined only by playlist references without duplicate library entries.

== Path Hash column ==

After running, you can show the '''Path Hash''' sort column in the Library to inspect the computed values. Songs with the same hash are duplicates by file path.

== Before you run ==

* '''Back up your library''' (Save Database) if you are unsure. This operation removes library entries and cannot be undone from within kJams.
* Quit any operation that is sorting the library; the command waits for sorting to finish.
* Read the confirmation dialogs carefully; the second dialog shows counts of groups and entries to be removed.

== Technical notes ==

* Path resolution uses '''Resolve As Far As You Can''' so aliases and broken path chains are normalized when possible.
* Volume names are normalized for consistent hashing on macOS.
* The feature is compiled only into the Qt build (`#if _QT_`); 32-bit editions do not include this menu item.
