[Gavriel]

  hello Exiftool :
I made a video to upload to facebook.I made the video with an mp3 of Guns and Roses "November Rain.mp3".
I reject the video facebook 
I download exiftool  but I do not know how to remove all metadata

c:\>exiftool (  ?  ) NRain.mp3

Sorry, but ExifTool doesn't have the ability to write/edit MP3 metadata.

my voice recorder date/time got off by 4 days 4 hrs 28 min

so i have about 40 mp3 files i need to correct date/time
not meta data, but file system create date and modify date

i tried with the date / time shift examples but error said wrong file type

exiftool ver 10.42 for mac

is there a way?

As long as you're talking about the FileModifyDate and FileCreateDate then it should work and it worked here on one of the two files I tested it on.

But I do have one file that it doesn't work on

Code Select Expand

C:\>exiftool -FileModifyDate+="4 4:28:0" -FileCreateDate+="4 4:28:0"  "Y:\!temp\test.mp3"
Warning: Error opening file for update - Y:/!temp/test.mp3
    0 image files updated
    1 files weren't updated due to errors

Since it's small, I've attached it.

It works for me:

Code Select Expand

C:\WINDOWS\system32>exiftool -ver
11.83

C:\WINDOWS\system32>exiftool -FileModifyDate+="4 4:28:0" -FileCreateDate+="4 4:28:0"  "W:\!temp\test.mp3"
    1 image files updated

It will be a permission issue if ExifTool can't open the file for update.  Check the file permissions.

Ah, yes, that was the problem in my case.  My mistake.

[lsolesbee]

thank you for pointing out command "-filecreatedate" and thanks for testing it

so -filecreatedate command did run, but for some reason  files were NOT updated [the date of the file did NOT change]  and getinfo [ ] locked is unchecked

----edit msg-----
i tried -filemodifydate AND IT WORKED !!!

so i tried -filecreatedate again, still no go same errors
-----------------
any ideas?


------------------------
what is the diff in the two commands:  -createdate   and -filecreatedate

CreateDate is metadata that is embedded in the file.  It mostly appears in image and video files.  I don't believe it applies to MP3 files.  FileCreateDate and FileModifyDate are part of the underlying file system, which keeps track of things like file permissions, filename and directory, etc.  They are part of every file on the computer.

I can't comment on the problem with the FileCreateDate, I don't use a Mac and they have some very different file system tags than does Windows.

[Phil Harvey]

Shifting of the MacOS FileCreateDate is not yet supported.  This would be difficult and slow because Exiftool relies on external apps to access this information.

So what you could do is shift the FileModifyDate as above, then copy that to the FileCreateDate afterwards
exiftool '-FileCreateDate<FileModifyDate' <FileOrDir>

Good point.  Or you could do this:

exiftool -tagsfromfile @ -filecreatedate -globaltimeshift "4 4:28:0" FILE

exiftool -tagsfromfile @ -filecreatedate -globaltimeshift "4 4:28:0" FILE

Ah, and FileModifyDate could be added to that to do it all at once.

exiftool -tagsfromfile @ -filecreatedate -FileModifyDate -globaltimeshift "4 4:28:0" FILE
