Title: Limits on the commandline
Post by: efry on February 03, 2011, 03:45:23 PM

Which limitations (if any) are there on the length of the commandline?

In my application there seems to be a failure, if the length of the commandline exeeds about 24200 characters, but it may be the application (written in VisualBasic) which causes the problem.

I have also tried to call ExifTool from a .bat-file, but also there it seems, that a very long commandline results in an error.

Is there a limitation on the number of files, which can be processed in a call to ExifTool?

Hi,

It's not Exiftool that limits that size (length).. it's OS. See here:

Hope this helps.

Thanks Bogdan,

Yes, there is a limit with the Windows cmd shell, but not with Mac or Linux shells.

The -@ option may be used to get around this.
