Overwrite warning when output filenames should be different

[stephenrjr]

The CD album in question is Fleetwood Mac - Tusk which is a 2 disc album that happens to have track 3 on each disc sharing the same name; the album is not a Compilation, but it is a multi-disc album.

Dynamic Naming:

[FRONTFOLDER]4[]/[IFCOMP]Compilations/[album][][IF!COMP][artist]/[album][]/[IFMULTI][disc]-[][track] [title]

Track Metadata:



I would expect the Dynamic Name to produce two distinct files:

(output base folder)/Fleetwood Mac/Tusk/1-03 Think About Me.flac
(output base folder)/Fleetwood Mac/Tusk/2-03 Think About Me.flac

Instead, this warning is issued:



Is this a bug, or am I misunderstanding something?

NOTE: On using the latest release version of Batch Converter 2026-05-25 (2)

From this documentation page https://www.dbpoweramp.com/Help/TuneFUSION/Naming


[IFMULTI]string[] string is included if part of a multi CD set (ie disc number > 1)

[IF!MULTI]string[] string is included if not part of a multi CD set (ie disc number <= 1)

Based on the definitions, it's unclear how IFMULTI and IF!MULTI currently interprets the Disc tag.

In my situation above, this would mean IFMULTI needs to:

Disc tag is `empty` or not present: IFMULTI evals to FALSE
Disc tag is a single number > 1: IFMULTI evals to TRUE
Disc tag is formatted as a two-part value ("disc_number/total_discs"); therefore,
if total_discs > 1: IFMULTI evals to TRUE

Is this how IFMULTI is *suppose* to work?

[simbun]

if total_discs > 1: IFMULTI evals to TRUE

With FLAC I believe the TOTALDISCS tag needs to be populated, as how else would you know that disc 1 is part of a multi-disc album.

CD Rippers naming puts disc number in, which would fix this issue:

[MAXLENGTH]80,[IFVALUE]album artist,[album artist],[IFCOMP]Various Artists[][IF!COMP][artist][][][]\[MAXLENGTH]80,[album][][IFMULTI], Disc [disc][]\[MAXLENGTH]80,[track] [artist] - [title][]

With FLAC I believe the TOTALDISCS tag needs to be populated, as how else would you know that disc 1 is part of a multi-disc album.

See the spreadsheet image I shared -- column AL shows what CD Ripper populated as dd/tt, where dd is disc number and tt is total discs in set. From what I can tell, IFMULTI is not interpreting the Disc tag correctly.

Spoon See the spreadsheet rows I shared -- column AL shows what CD Ripper added to the Disc tag.

Does IFMULTI reference this tag when performing Batch Convert ?

As you can see from my original post, I already include the [disc] value output in my Dynamic Naming string, but IFMULTI is not evaluating to TRUE.

I did see the screenshot, but I tested with the latest Windows trial (2026-05-25) and it worked with TOTALDISCS. Maybe it's a bug in the mac version.

I've just checked my tags and I'm using DISCTOTAL not TOTALDISCS, though they both appear valid.

I'd double check one of your files to make sure it's not stored as dd/tt as I don't think that's valid in Vorbis.

Correct

Indeed, this file and the counterpart in question have the appropriate tags, it appears. But this still doesn't explain why my Dynamic Name using IFMULTI didn't actually trigger and output a `1-` or `2-` for ANY of the tracks. Is there anything wrong with my Dynamic Name string?

IFMULTI detects if disctotal is greater than one. For that flac file it should, if not post your whole naming string as the error might be elsewhere.
