Our company's development team uses IIS to upload jpg files to the sftp server. The source file is only 100Kb, but the file on sftp is 3TB. Open these files with a hexadecimal tool and find that they are all "00" completion bits. There is still the following warning log information on the IIS server. Does anyone know the reason?
