Optionally, for path portability: use the "%OpenXXDir%" argument in the "Program" field. For example, if Open++ is located in x:\apps\open ++ and you want to add a program from the Opera folder, enter %OpenXXDir%\..\opera\opera.exe in the "Program" field.

Does anyone know of a way I could use this as a replacement "Sendto" menu. There's no software I've found that can do it. I would love to make my Sendto menu more portable when reinstalling Windows.

@the_watcher - I'm on Win 8.1 and don't use Windows Explorer that often so I can't really verify. I use CubicExplorer.

I've got a lot of crashes with Windows Explorer on windows 8, having open++ enabled. Switched to filemenu tools, which seems to behave better.

^erm, seems I spoke to soon. The ability to run programs with elevated rights seems to be broken for items with relative paths.


Ascend4nt 2013-05-16 21:26

Wow, can't believe I missed the ability to run any of the items from the Open++ menu in elevated (admin rights) mode by just holding down the Shift key! And I've been using this for quite some time now (and actually rely on it).

With ref. to previous post (checksum maximum 16 files).

Explanation and workaround (tested & working!) offered by dev.

This issue should be a command line length limitation issue. The maximum length of command line on Windows is 2048, the Open++ needs to reserve 263 characters for the program path in the command line which leads to only have 1785 characters for arguments that can be used to store all file paths. So if the average path length of each selected file exceeds 110 characters, Open++ will only be able to handle 16 files.

Here is the workaround to let Open++ handle more files if you change the settings of "View File Checksum" command exactly as indicated below. The downside of this workaround is that the Open++ will not be able to calculate the checksum of the files which are not under the same folder.

Parameters: ViewFileChecksum %FileNames%

Working directory: %FileDir%

I've been testing this out and I have to say, this is brilliant! Works great on restricted PC's as well as on my own home PC. A much better idea than the 'Cafe' style of double-click interception IMO.

@SD: If the selected files are from a deeper folder, the maximum is still 16 or less?

I seem to have discovered a little bug in Open++ v.1.5.1, which -by the way- is an EXCELLENT application!!!
When calculating file's checksum I selected 34 files but Open++ only calculated the checksum for a maximum of 16 files.
I repeated the same procedure a few times (always selecting more than 10 pairs of files, so 20 files minimum) but it looks like there is no way to make Open++ calculate more than (8 pairs) 16 files at a time.
Does anybody have a solution?
