Possible bug in [SendTo] Multipar

[Tigerman]

I have added Multipar to the [SendTo] menu.
When sending many files to Multipar I get "Filename or Extention too long" error. When I use Drag 'n Drop the same files into Multipar there is no problem.

I did some testing and the number of files is not the problem, in one directory I could add 319 files without the error, but adding a random 320th file gave the error.
In another directory I could add 324 files without the error, a random 325th gave the error.
My guess (also looking at the error message) is that there is a total number of characters that can be send to multipar.

When sending many files to Multipar I get "Filename or Extention too long" error.

 Will you capture the screen-shot of the error message and post here or send by mail ? If it is an error of your OS, I cannot help you, because it is a problem of Microsoft. The maximum number of possible characters depends on OS version.

 You may use "Shell Extension (Integrate MultiPar into Shell)" instead of [SendTo] menu, if you select many files often. When many files are selected, Shell Extension DLL uses a temporary file to send filenames, then there is no limit number.

You're probably right and it's the OS that gives the error. When using the shell it does not give the error.
I used "Send To" because on my system Multipar shell is in X64 sub-menu, so "Send To" is a bit shorter.
But will use the shell in future.
 
Thanks for the clarification.
