Overwrite image of the same file name with different file size #44

This situation sometimes occurs. Several files from D5600 are already in the local folder. eg) DSC_8797.JPG DSC_8798.JPG DSC_8799.JPG DSC_8800.JPG

When a picture taken on another D3200 is transferred, the existing file is automatically overwritten. Although the file name is the same, the picture content and file size are completely different... As a result, the first 4 photos of D5600 are disappearing forever.

If the name of the file in the local folder is the same but the file size is different, it is reasonable to rename and transfer as follows. eg) DSC_8797-1.JPG DSC_8798-1.JPG DSC_8799-1.JPG DSC_8800-1.JPG

Is it technically possible? For reference, in the same situation the previous eye-fi sd renames the files and transferred.

This behavior is intentional. It is for overwriting a file corrupted during the previous copy. To be honest, I have not expected that anyone may risk their files by using the same local folder when a file name can be duplicated. I recommend not to specify the same local folder in such case in the first place. But it can happen accidentally. So I add setting not to overwrite existing files. https://github.com/emoacht/SnowyImageCopy/commit/25093ecc61606e9514b71a7794beb5d575c7396f https://github.com/emoacht/SnowyImageCopy/commit/e90ea92831b8a1aa44b39c4a69cb457f5460b35a Please note the number of same file name files are limited to 65535.
