whats the limit for commandline arguments?

[MrPolite]

I'm dragging a lot of files to my app's exe file and it's supposed to open them. I tried to drag 1700 files at the same time and dropped them on my app's exe, but windows gave me an error and said that it can not find my app. I tried this same thing with some other random programs and got the same error message. So I'm wondering, what's the limit to the number of files you can pass as commandline arguments to a program? I'm gussing windows puts a limitation on this

hmm weird I cant do it with more than 23 files

Environment / CreateProcess limit is 32767 characters - which is the one I'd think applies in your case.

NT DOS (cmd.exe) command line is limited to 8192
Old 'DOS' was 127 i think.

I may be wrong though!


23 files seems a tad small to be hitting the above limit though.

have you tried doing one file, then two files, then 3 files yadda yadda? seems tedious but it would be a sure-fire way to see if there's one file in particular clogging your system so-to-say.
