FileGetSize()
OutputVar := Mfunc.FileGetSize([Filename, Units])
Retrieves the size of a file.
Filename
The name of the target file, which is assumed to be in %A_WorkingDir% if an absolute path isn't specified. If omitted, the current file of the innermost enclosing File-Loop will be used instead.
Units
If present, this parameter causes the result to be returned in units other than bytes:
K = kilobytes
M = megabytes
Returns the retrieved size (rounded down to the nearest whole number).
Throws MfException is non-zero then InnerException has a message of A_LastError
Wrapper for AutoHotkey Docs - FileGetSize.
Static method.
Files of any size are supported, even those over 4 gigabytes, and even if Units is bytes.
If the target file is a directory, the size will be reported as whatever the OS believes it to be (probably zero in all cases).
To calculate the size of folder, including all its files, follow this example:
SetBatchLines, -1 ; Make the operation run at maximum speed.
FolderSize = 0
WhichFolder := Mfunc.FileSelectFolder() ; Ask the user to pick a folder.
Loop, %WhichFolder%\*.*, , 1
FolderSize += %A_LoopFileSize%
MsgBox Size of %WhichFolder% is %FolderSize% bytes.
Any and/or all parameter for this function can be instance of MfString or var containing string.

OutputVar := Mfunc.FileGetSize("C:\My Documents\test.doc", "K") ; Retrieve the size in Kbytes.
