If a file is created in a folder that is being synced and then grows in size, the correct file isn't synced in the end.
Example:
I’m rendering a video. At the start of the rendering process, the file is created with a size of 0 KB. This is synced immediately. Afterward, the file keeps getting larger as the video is being created. However, the Cloudreve client doesn’t recognize this and stops syncing the file.
In the end, the file is several GB in size, but on the Cloudreve server it is only a few KB.
This means that Cloudreve only checks the creation date and not the last modification date.
