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)

[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?

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][]

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.

hexdump -C --length 3096 01.01.flac

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
