WinSCP incorrectly uploading files when custom command run

Select a local directory and corresponding remote directory.

Execute custom command: "C:\Program Files (x86)\WinMerge\WinMergeU.exe" /u /r /s /x "!^!" "!"
(Apply to directories: ticked, Local command: selected)

Remote files are downloaded to temporary directory.

WinMerge opens correctly etc.

Close WinMerge.

WinSCP attempts to upload local files.

Problem did not occur in versions prior to 5.7

WinSCP version 5.7

Thanks for your report.
Will check it and contact you later.

I would have to double check, but I'm reasonably sure it is trying to upload the actual local ones - specifically, the first file from the remote directory alphabetically (I'm unsure if it would try with the second one too - I cancel it on the first one). I only noticed when it popped up a "do you want to overwrite this file" prompt, and then on some subsequent testing I believe I noticed it upload a file from the local directory which was not already present in the remote directory (i.e. it did not pop up the overwrite confirmation).

However I will test further to confirm that.

I did not modify the local files in any way, but possibly a bug with WinMerge or some other part of my system may have made it seem as though they were modified.

Is there any way to control this behaviour?

No it really uploads the local copy of the remote files.

I have sent you an email with a development version of WinSCP to address you have used to register on this forum.

The dev. copy you sent fixes this problem.

However if all it is doing is uploading the remote files, while inefficient and pointless when they haven't changed, no data should be lost so I can probably live with that problem until a new version comes out with it fixed!

Thanks for the prompt fix.

Yes, it does not work for directories atm. Will try to improve it.
