func GetFileInfo

func GetFileInfo(filename, uploadDirectory string) (os.FileInfo, error)

GetFileInfo returns information about a file in the upload directory.

func GetFileSize

func GetFileSize(filename, uploadDirectory string) (int64, error)

GetFileSize returns the size of a file in the upload directory.

func GetFileStats

func GetFileStats(uploadDirectory string) (fileCount int, totalSize int64, err error)

GetFileStats returns statistics about files in the upload directory.

func GetImageInfo
