RangeError [ERR_FS_FILE_TOO_LARGE]: File size (***) is greater than possible Buffer: *** bytes

Hi,

today i installed drop-dat via npm on my latest Linux CentOS 6.10 and when i try to share large file , i see:

$ drop-dat vzdump-1.tgz
Importing file(s):
  vzdump-1.tgz
RangeError [ERR_FS_FILE_TOO_LARGE]: File size (18561994013) is greater than possible Buffer: 2147483647 bytes
    at FSReqWrap.readFileAfterStat [as oncomplete] (fs.js:260:11)

When i paste 2147483647 into https://whatsabyte.com/P1/byteconverter.htm i see that it is 2048MB which is 2GB

[root@me abc]# df -h

[root@me abc]# node -v

This is VPS based on OpenVZ virtualization. I have enough free space, how can i increase that buffer or move buffer so it utilize my free HDD space? Or how to share such big file?

That is the max buffer size in node. To import larger files, the code will need to change the imports to streams instead of putting the whole file in a buffer: https://github.com/creationix/drop-dat/blob/master/drop-dat.js#L76
