Find Files: How to find mp3 files by bit rate

[Jerry]

[Using 16.10.0300 on Windows 7 Pro 64bit.] I can't get a find file search to work properly using the bit rate property for mp3 files. I am in a folder containing a hierarchy of subfolders with mp3 files of different bit rates (mostly 320 kbps, but some 256, 192).

I am using the following settings in Find Files:

• All Types
  Mode: Standard
  Include Subfolders
  Follow folder links
  Auto sync
  Attributes: Not Directory

I then try each of the following Name expressions unsuccessfully:

• prop:Bit rate:!=320 returns all mp3 files
  prop:Bit Rate:!=320 returns all mp3 files
  prop:BitRate:!=320 returns all mp3 files
  prop:Bitrate:!=320 returns all mp3 files
  prop:bitrate:!=320 returns all mp3 files
  prop:#audio.bitrate:!=320 returns all mp3 files
  prop:Bit rate:<320 no results
  prop:Bit rate:192 no results
  prop:#audio.bitrate:192 no results

Do you have to specify the kbps unit label in some way with this property?

E.g.

Code: Select all

prop:#audio.bitrate: == 192 kBit/s

Finds all files with exactly that bitrate...

Ok, so you need to put a space after the ":" and after the comparison operator. And for this property, you DO need to specify the unit label also (kBit/s), but curiously you need only specify it partially to work: == 192 k works also. Is that a general feature for properties with required unit labels?

And why doesn't any of the "Bit rate" variant spellings work? Is it because of the embedded space? If so, what do you do when a property has an embedded space and there's no Special # Property for it?

Didn't try it with a short form, can't comment on that

Wrong format

If so, what do you do when a property has an embedded space and there's no Special # Property for it?

Like? I'm not aware of any properties with a space in it

Apart from that, two options, property index (can be different with each OS) or the canonical one from

Can you elaborate on that?

Such as any of the properties with embedded spaces listed in say, Configuration > File Info Tips.

[highend]

Spaces in properties must be passed with an underscore.
If all "normal" properties should work in the gui search? I don't know, never tried them.

I only use internal xy properties / canonical ones (be careful, the latter are case sensitive).

I see. In my case they currently use the german name and I'm too lazy to set my OS language to english to change that
