#468 Can't find any log file or description about log file by using 7zip

[Yue Yao]

Hello Igor,
7zip is a great application. thank you!
but I can't find any log file or description about log file or command line parameter about log file ( except redirect ). Is it really the case? A log file for the zip/unzip tasks with min. for example, used parameters, statistic(directories, files) and task status ( date/time, SUCCESSFULL or FAILURE...) it is very important, if the tasks take long time and work with huge data... also for documentation purpose. At least logs/logfile simipar as from MS robocopy...
Maybe you can give me some advices?
Thanks
yue

There is no any description now.

sadly. But I think you should log something during the tasks, more or less, anywhere which users may archive them self, instead of only see them in GUI?

you can view log file so:

7z t a.zip > log.txt
7z t a.zip -bb9 > log9.txt

ok, I found a workround out of box:
1. after a big archive task and before to deliver it, do with 7z.exe t big_example.txt >big_example_status.txt. check the file big_example_status.txt, if there is any Error/Warning.
2. before to extract a big_example.zip do 7z.exe t big_example.zip and check the output.

for me the big_exqampl.zip ( with sub zip files)with errors ist about 50GB and the check required only a few minutes.
thanks for the great utility!
