I am using CloudBerry Explorer. And there are some files that I want to unzip them. First, I can find these files' addresses. For expamle; user/abc. And in this abc, there are 5 zip files. How can I unzip them, and merge them?
Thanks,
You could try using the java.util.zip package. I suggest you read through the explanation: Compressing and Decompressing Data Using Java APIs

I have a folder in s3bucket. I want to zip the files inside it and then download the zip file. Whatever i found was related to lambda. Is there a way i can do it without using lambda? if not then what is the proper way to do it.
Thank you in advance.
S3 can't zip it on the fly for you since it's only a file storage service. You could use lambda of course, but the simplest way to download a "folder" on S3 is to use the AWS CLI.
aws s3 sync s3://<bucket_name>/<folder_key> <local_dest_path>
You can then zip it on your local machine if needed.
For some reason I am not able to download my output files from colaboratory. I am able to upload input files but I can not download my output files separately. I am also using a mac.
For information on various ways to download files from Colab, see https://colab.research.google.com/notebooks/io.ipynb.
I have a .tar.gz file. Now i need to unpack these files with SSIS package. Previously did unzip and delete for .zip files with the help of For each container and script task. Not sure how to do it for .tar.gz files. Any help?
You can use an execute process task to achieve this (or using process from Script task), but you have to install a ZIP application like 7Zip or Winzip or else. And use command line to Zip or Unzip archives.
Follow one of these links for more details:

7Zip command line examples
What command line parameters does WinZip support?
You do not want to download the tar file.
Just download select few files inside the tar.
Does s3 provide any API to do this or is Apache Commons Compress my best bet?
While you'll be able to stream the file from S3 you'll still basically download it. The Apache Commons Compress library will help hide some of this and is a good solution. The other option would be to store the individual files in the tar file so that they can be randomly accessed.
My goal is to locally save a BigQuery table to be able to perform some analyses. To save it locally, i tried to export it to Google Cloud Storage as a csv file. Alas the dataset is too big to move it as one file, thus it is splitted into many different files, looking like this:
exampledata.csv000000000000
exampledata.csv000000000001
...
Is there a way to put them back together again in the Google Cloud Storage? Maybe even change the format to csv?
My approach was to download it and try to change it manually. Clicking on it does not work, as it will save it as a BIN.file and is also very time consuming. Furthermore I do not know how to assemble them back together.
I also tried to get it via the gsutil command, and I was able to save them on my machine, but as zipped files. When unzipping with WinRar, it gives me exampledata.out files, which I do not know what to do with. Additionally I am clueless how to put them back together in one file..
How can I get the table to my computer, as one file, and as a csv?
The computer I am working with runs on Ubuntu, but I need to have the data on a Google Virtual Machine, using Windows Server 2012.
try using the following to merge all files into one from the windows command prompt
copy *.cs* merged.csv
Suggest you to save the file as .gzip file, then you can download it from Google Cloud easily as BIN file. If you get these splited files in bigquery as following:
Export Table -> csv format, compression as GZIP, URI: file_name*
Then you can combine them back by doing steps as below:
In windows:
add .zip at the end all these files.
use 7-zip to unzip the first .zip file, with name "...000000000000", then it will automatically detect all the rest .zip files. This is just like the normal way to unzip a splitted .zip file.
In Ubuntu:
I failed to unzip the file following the method I can find in internet. Will update the answer if I figure it out.
