- Search the existing issues.
- Refer to the FAQ.
- Refer to Differences between Windows PowerShell 5.1 and PowerShell.
Steps to reproduce
I have a digital camera memory card with a root folder DCIM and 3 sub folders - the first contains ~ 250 files, the second 500 files and the third ~250 files. Average size is 44MB Roughly 44 GB to copy.
Copy speed from my card reader is ~100MB/sec, so copying the recent files from one folder will take 1-2 minutes, and the new progress bar would be nice.
copy D:\DCIM\140PENTX\* C:\temp\deleteme\ -Recurse
Displays no progress
copy D:\DCIM\* C:\temp\deleteme\ -Recurse
Displays progress as in the video at #18735 HOWEVER it only shows the count of files and number of bytes to copy for the first directory. ie. instead of 1000 files /44 GB it shows 251 files,
Expected behavior
All large copies show progressActual behavior
Copying a lot of data from one directory does not.Error details
No error. Command runs, but shows no progress.Environment data

The problem is that when copying a single folder, it's just a single .NET API call, so there's no way to know and write progress. We would have to split it into individual copy calls to be able to render progress which would slow down the operation. I think the best we could do is show a "progress" pane with the total number of files to be copied, but it wouldn't show progress, just that copying was happening.
If the WG decides not to add a static progress pane, then we should at least document this behavior so it's not surprising.

Thank you James O'Neill (@jhoneill) -- The Interactive WG reviewed this issue. The implementation of this feature is not fully understood and needs further investigation. We are planning to address this during the 7.5 development timeframe.

@PowerShell/powershell-committee discussed this. We can investigate showing a static progress message when copying lots of files that don't result in subfolders being copied.

The issue I reported above was it actually reports wrong information, the numbers given being the first directory of multiple ones.

James O'Neill (@jhoneill) just had a fix merged in, can you check if this is still a problem after we have a release with that change (or if you're adventurous build that branch)
