how do you open more than 15 files at once on Windows 7 at once (by selecting them and pressing enter makes it go to a random print page)?

all the files are the same type -pictures

AFAIK, you can't. – Mehrdad Jun 23 '11 at 3:02
@KContreau: Is it different for different kinds of files? – Mehrdad Jun 23 '11 at 3:03

@Mehrdad Yes, if the files are all opened by the same program, they can be opened by selecting them all and hitting enter, or right-clicking and hitting open. If they are not opened using the same program, you can't, and the open menu item won't be there when right-clicking. – KCotreau Jun 23 '11 at 3:07

@chabad Ahh, I understand the problem now. There is a limit. I will see if I can find a regisrty entry that breaks that limit. I was able to put 16 .jpg files in a folder, and if I click 15, the open menu is there, but click all 16, and no menu item. – KCotreau Jun 23 '11 at 3:13

Open regedit and navigate to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

Add this case-sensitive DWORD (32-bit) key:

MultipleInvokePromptMinimum

Set the value to

16

P.S. 16 is not a hard number, but actually indicates "unlimited", so putting in 17 probably will not work.

+1 you just pwned me. :) Nice answer, this is actually very useful! Hope you get lots of upvotes! – Mehrdad Jun 23 '11 at 3:28
can i put in whatever number instead of 16? – chabad Jun 23 '11 at 3:40
@chabad Actually, if you read the last line, I just edited my answer a few minutes ago to address that exact question. – KCotreau Jun 23 '11 at 3:41

That's because you need to type in decimal not Hexdecimal 16 in decimal would make it unlimited. and make it 10 in hex. it worked for me. :D

This answer makes no sense without context. Please clarify (or write that you are referring to a previous answer). :) – iglvzx Nov 22 '11 at 16:29

on my system, 16 allows only 22 files to be open at once Setting DWORD to FF to allow up to 255 files (I've tested it only up to 112 !)
