我从服务器下载 了一个 大小20m的日志文件，在本地打开后是空白，我又做了其他测试，如果下载一个很小的的文件是没有问题的，我测试了5m左右的.txt文件，下载后打开同样是空白
I downloaded a log file with a size of 20m from the server, but it was blank when opened locally. I also conducted other tests and found that downloading a very small file was not a problem. I tested a. txt file with a size of about 5m, and it was also blank when opened after downloading
