I'm trying to back up about 300 GBs of photo from the OneDrive camera roll folder on my C drive.
The destination is another drive, another drive letter.
I have tried several utilities (including xcopy and) and none of them work. Every single one of them fills all available space on C drive. even 20 GB worth, with some unknown type of data. This is something that should not happen at all because this operation is creating new copies of files on the e-drive and only looks at what's on the C drive.
FreeFileSync s nice on paper but it throws zillions of "ffs" errors, which I believe refer to the anger if the user instead of an acronym for the product. Other methods of copying give cloud errors and crash on them even though I'm not touching the cloud whatsoever in this operation.
I would like a reliable error-free file copy, utility suitable for this, and one that uses very little or no source storage during the process.
Thanks
