A friend has zipped a large csv file (15GB) for me and put it on amazon s3. Unfortunately, I am unable to extract the zipped csv file once downloaded. At first, I thought it was simply corrupted from the download. I had the friend re-upload now 4 times.
The error that I get is: unsupported commpression method. When I ran the 7z info command, the compression method on the file said 'Deflate', which seems to be the default.
I'm wondering if its simply a windows file size limitation. I'm on Windows Server 2008 R2. I also attempted to use Zip2Fix utility to repair the zip but got an "out of memory error".
details boiled down:
zip file size : 15GB
inside zip : 1 csv file
os: Windows Server 2008 R2
transfered via S3
error: compression method not supported
Thanks in advance for any suggestions.
If your server is on a FAT32 partition (though very unlikely), the max filesize that you can expand is 4Gb. I would highly suggest that your friend re-uploads the file in <4Gb chunks as almost any part of the process could be 32bit-size limited.
