Re: Windows vs stat() Directory Size

["Bill Meecham" <bmeecham@xxxxxxxxxxxxxxxxxxxx>]

folderName=813
Contains 1 text file 4 bytes 

winSize=4 bytes
st_Size=8192

winSizeOnDisk=4096 bytes
st_allocSize=8192
For this small example the allocated size is doubled.


For larger folders I add up all of the folder sizes within the folder and in 
one case get

winSizeOnDisk=4,251,648 bytes
st_allocSize sum=118784 bytes

thanks

  No idea for sure but a couple of guesses:

  - Actual vs. allocated size (Windows equivalent is probably 'Size' vs.
  'Size on Disk')
  - 1000 bytes/K vs. 1024 bytes/K

  How different is 'very'?  Can you provide an example or two?

  Hello,

  i have a pgm that retrieves the allocated size of a directory using
  readdir() and lstat() and stores the dir name and size in a file which I
  then graph for historic size allocation and reporting.

  when I map the ifs to winexplorer and look at the properties of a
  directory the allocated size is very different.  

  Anyone know why?

  thanx
  bill
