Unable to unzip large files

[jwollbrett]

the unzip R function is used to unzip files.
I found this information in the documentation of the function :

The default internal method is a minimal implementation, principally designed for Windows' users to be able to unpack Windows binary packages without external software. It does not (for example) support Unicode filenames as introduced in zip 3.0: for that use unzip = "unzip" with unzip 6.00 or later. It does have some support for bzip2 compression and > 2GB zip files (but not >= 4GB files pre-compression contained in a zip file: like many builds of unzip it may truncate these, in R's case with a warning if possible).

Then it is not possible to use this function for large files (undependently of the Operating System).

I didn't find R package allowing to unzip large zip files.
It could be possible to use the following code for Unix and MacOs

sysinf <- Sys.info()['sysname'] if(sysinf == "Darwin" || sysinf == "Linux"){ system2("unzip", args = c("-o", file), stdout = TRUE) }

I do not know if unzip is known by default in Windows.....
What should we use for Windows users?

R.utils::decompressFile could be used to decompress .bz2 or .gz files

On any platform? Let's compress our files in gz then.
