Copying file itself into clipboard in Notepad++

@Alan-Kilborn Is that for Python 3? I got an error with Python 2.7:

@Alan-Kilborn - Sorry I’m late to the party, but real life is keeping me very busy at the moment. :-(
I looked through my script, but no, it doesn’t seem to be mine … maybe it’s one of the scripts that fell victim to my hard disk failure and that I hadn’t backed up. But I can’t really remember that I ever needed this either. Anyway … but your script works :)

@mkupper - Python doesn’t know where to look for the method. Change addressof t0 ctypes.addressof and I assume it will work with PS2 too.

Given the above geneltmen’s exposition, it look slike it does not worth it, and any solution would be too complex to implement for this. Probably just use right mouse button -> open file folder, then ctrl+c

Thanks everybody

Hmm, solution provided.
Set up the ability to run the given script, then assign whatever free keycombo you want for it.
There are details about using scripting HERE.

Hmm, solution provided.

The solution that was provided only puts an CF_HDROP format blob into the clipboard. On my WIndows 11 machine that’s not enough information to then do a Paste in Windows Explorer and for a copy of the file to appear. However, if the OP only needs or desires an CF_HDROP then yes, the PythonScript provided does that.

If someone wants or needs for Notepad++ to better emulate the behavior for when someone does a copy/paste of files from one Windows Explorer window to another then the solution will need to include more blobs in the package that’s uploaded into the clipboard. On my Windows 11 machine a “Copy” uploads the 16 blobs that I mentioned in a previous post to this forum thread. Some of those 16 are likely redundant meaning we don’t need all 16 for a paste to work. CF_HDROP is one of the pre-defined clipboard blobs and thus is among the low hanging fruit of the 16. Many of the blobs that Windows Explorer uses are not pre-defined. To inject them into the clipboard as part of a package of blobs you need to first translate the blob name, which is well known, into the current blob numbers being used by Windows Explorer and you add them to the clipboard using the numbers.

The blob numbers change from time to time. For example, today I did a copy from Windows Explorer and while the list of blobs looks the same as what I got a couple of days ago I see that
$DataObjectAttributes$ changed from 49905/0xC2F1 to 49647/0xC1EF and
$DataObjectAttributesRequiringElevation$ changed from 49981/0xC33D to 49997/0xC34D.

In looking over the list I believe the numbers assigned to 15 of the 16 blobs will change from time to time. The only one that’s constant is CF_HDROP (blob format number 15/0x000F) which is pre-defined. The numbers change because Windows Explorer (explorer.exe) registers the blob names with the clipboard system and gets a blob number or handle for that name back from the clipboard when you log in. Other background processes also are registering names with the clipboard system and getting handles to them. Blob handle numbers can, and likely will, change when you reboot a machine.

Well, exactly that worked for me. And I think it worked for Ekopalypse based on what he said.

When I run the script to “copy” the data, Ditto (a clipboard manager) shows:

(Note that when I took the screenshot, the file-copy was Ditto entry number 2, not 1.)
It sure LOOKS like the copy was a file, from the Ditto data. I’m not sure what the funky characters are, likely binary data that Ditto isn’t interpreting for good presentation to the user.

But I’m not “selling” the script as appropriate for everyone; I didn’t write it and haven’t looked super-hard at it. As I said, I was reluctant to post it in the first place, given I didn’t know its origins (I still think it was an Eko creation!).

If some feel the script isn’t robust or doesn’t work, feel free to take on the task of improving it.

Maybe I’m missing something but it seems to work for me as well.

(ugh. I accidentally pasted a CF_HDROP while writing my reply, rather than pasting the text I meant, and it confused my browser and I lost the active page, including the whole post I had written. so now I am recreating it :-( )

After the OP re-asked this question, and I directed him here, I decided to try it out (since I don’t think I tried it last Autumn).

My first experiments were unsuccessful.

First, like @mkupper, I had problems with addressof, but unlike @mkupper, I am using PythonScript 3.0.22, so it wasn’t a PS2 issue. Still, that was easy enough to fix.

Second, for the first file I tried, having just the CF_HDROP and trying to paste in Windows Explorer did nothing.
But looking at @ekopalypse’s video, I noticed he had a pretty simple file path, so I tried with a different file, and that one worked.

I see that the script is doing the dump_mem to show the structure used, so here’s some information about the differences in the sequences

Destination directory: C:\Users\pryrt\Downloads\

So then I went to c:\TEMP and made a bunch of files (1, 12, 123, … 123456789x, 123456789x1, … up to the MAX_PATH limit ), and changed the destination directory to C:\Users\pryrt\Downloads\testfolder\

I tried with 1 and 12 and they both worked…

[20, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 99, 0, 58, 0, 92, 0, 84, 0, 69, 0, 77, 0, 80, 0, 92, 0, 49, 0, 0, 0]
[20, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 99, 0, 58, 0, 92, 0, 84, 0, 69, 0, 77, 0, 80, 0, 92, 0, 49, 0, 50, 0, 0, 0]

I didn’t want to test everything, so I skipped forward to 123456789x1

[20, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 99, 0, 58, 0, 92, 0, 84, 0, 69, 0, 77, 0, 80, 0, 92, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 0, 0]

but it didn’t work when I pasted.

(Just to be clear: there is never an error in PythonScript shown; I am just showing the dump, in case there is useful information about the difference there. On a “working” run, I get the dump shown, and when I paste in my destination directory, it copies the file, or asks if I want to overwrite the file, depending on whether the file exists or not; on “didn’t work” runs, when I paste in the destination directory, apparently nothing happens – no new file is pasted, no request to overwrite, no Windows popup; just nothing happens. And I can confirm on those that the CF_HDROP still looks the same )

Then I went to the last file, with the biggest name, and it worked:

[20, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 99, 0, 58, 0, 92, 0, 84, 0, 69, 0, 77, 0, 80, 0, 92, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 120, 0, 0, 0]

… so it’s not path length alone.

Then I went back to 123456789x1, and this time when I pasted in the destination directory, it worked.

I went to some random files, and switched back to the 123456789x1 file: most of the time, I was able to copy it, but rarely, I was not. Then I went to c:\TEMP\post.md (this post that I’m typing up – not going to lose my work a second time), and after about a dozen times of trying (closing/reopening file, doing another file in between), it wasn’t working; but just after typing it up that “no matter how many times” I tried, it failed, then I do it one last time, and now post.md pastes just fine.

I cannot tell what the difference is, but Windows 11 seems to be flakey on the CF_HDROP. I don’t know if the other fields that @mkupper mentioned would make it more reliable, or if there’s some pauses or delays that the script could insert in order to get it more reliable, or whether it’s 100% up to Win11’s whims. Anyway, that’s what I saw as I experimented with this script.

fml2

There is a program called Far Manager, it’s an open source console based file manager. It has the capability to “copy” files so that they can be later “pasted” in Windows Explorer. Maybe we could look how they do it?

Ekopalypse

@PeterJones
hmm … if it sometimes works and sometimes doesn’t, then I suspect an alignment problem. I’ll have a look later today and see if that’s the case.

@fml2
thx, yes, that might be helpful.
