Hi,

I am writing a batch script to find sum of size of files present in a directory which contains payments as a word

On executing below code:

set Size_slu = 0
for %I in (c:\Systems\SLU\*payments*.xml) do set Size_slu+=%~zI
echo total file size :%size_slu%

Above code gives me only the size of the last file although it displays size of all individual files in command prompt, How can I sum up those sizes ?

What I have tried:

set Size_slu = 0
for %I in (c:\Systems\SLU\*payments*.xml) do  set Size_slu+=%~zI
echo total file size :%size_slu%

I do not think batch scripts have a +=operator.

As @Richard-MacCutchan has pointed out, you cannot use += in batch files you need to use the long hand version (caveat - untested)

set Size_slu = 0
set TotSize = 0

for %I in (c:\Systems\SLU\*payments*.xml) do  ( set Size_slu=%~zI
set TotSize=TotSize+Size_slu )

echo total file size :%Tot_slu%

Note the brackets as I've split this over two lines, although the following should also work

for %I in (c:\Systems\SLU\*payments*.xml) do  set Size_slu=Size_slu+%~zI
