Hi there,
not sure if I am in the right place but here is my question.

I have a file that is over 100mb and my host does not allow FTP of files above 100mb so I thought I would use a compression utility to compress it into smaller parts say 10mb each, upload them and then re-assemble them on the server back in to the 1 large file.

So first off what is the best or easiest software to create multi part compressed files, and what format should I use.

Second is how do I re-assemble the files once they are on my server, I do have SSH access if this helps.

My host says it is UNIX based.

1.- You can use the split command

split -b Number [ k | m ] [ -a SuffixLength ] [ File [ Prefix ] ]

split -b 1000 k Filename-to-be-cut

then you get "N" Files with name xa[a-z] with 1MB

2.- You send all files it using FTP.

3.- Then you can use the cat command

cat xaa xab xac ... ... ... > Filename-to-be-joined

check and see if you have unzip or unrar on the unix machine, if you have either then you can use the windows counterparts (sounds like your using windows) to create multipart archives of your files or file.

So in Winrar this is 'create new archive + split to volume bytes [25mb]' and it will make as many 25mb pieces has needed and then you can 'unrar x filename.rar' and it will deal with the files just fine.

Most files have a similar split/combine method. Though using this method will give you the assurance with checksums and what not that everyone is as it should be.

I have unzip on the server so used winzip to create multi part files, uploaded to server, logged in and used command.....

unzip filename.zip

the following was received....


[****.net@*****]$ unzip robbie.zip
Archive: robbie.zip
warning [robbie.zip]: zipfile claims to be last disk of a multi-part archive;
attempting to process anyway, assuming all parts have been concatenated
together in order. Expect "errors" and warnings...true multi-part support
doesn't exist yet (coming soon).
file #1: bad zipfile offset (local header sig): 4

I made this archive on my windows xp machine and then uploaded to my host which I am sure in unix/linux, will it be easier or better using another format rather than zip/rar as I dont seem to be having any luck with this?

Any help on this?
