My question involves the inability to upload files that are larger than approximately 100 Mb. When I attempt to upload a file larger than 100 Mb, at around 97% of the upload I receive the error message “413 Request Entity Too Large”. I believe this is a WebDAV error and not one produced by WinSCP. I am able to download much larger files without issues (I’ve successfully downloaded a 20 Gb file without problems). It is only when I attempt to upload files that the error occurs.
I’ve done some online reading and found a discussion about the registry setting
HKLM\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\FileSizeLimitInBytes. I’ve checked it and it is set to
50000000, as the articles describe. The literature says this setting has something to do with WebDAV download limits, but that doesn’t seem to be the case since I’m able to download much larger files than that without issues.
I believe the problem is not necessarily directly related to WinSCP itself, but I was hoping someone might have an idea how to fix this issue since you are familiar with what it takes to connect to a OneDrive account. Thank you for your help.
