Hello. It would be very useful thing if someone would make that feature for rclone.
As you know, NTFS file system do not support checksums. Some remotes explicitly require that file checksum would be provided before the upload. Those checksum files can be generated with Total Commander, HashCheck Shell Extension and other similar utilities.
So rclone should be able to load any .md5/.sha1/.svf/etc. file in the folder and check if it has checksum for the file which is about to be uploaded. Those checksum files seems to have same structure between each other. Maybe there are some minor differences, like comments or Unix format. That feature could be enabled by using "--enable-local-checksum-files" or similar flag. It should prefer checksum file which completely matches (with or without file extension) filename of the checksumed file. If no checksum for particular file is found or provided checksum is incorrect for some reason, it should fall back to regular file upload behaviour. There should also be declaration for manual checksum file if they span many folders. For e.g.: "--use-local-checksum-file Stuff.md5". The problem is that such multi-level directory checksum files are relative and rclone should figure out for which file which checksum should be applied. But that shouldn't be big problem as that checksum file itself should be in correct relative directory position. Also there should be flag which sets if you want your checksum files to be uploaded together with other files: "--upload-local-checksum-files true/false".
Could I expect that such feature would be implemented in the near future? That would potentially save me quite a lot of time while uploading.
