Right-click on the file and choose “Split file…”.
In the box labelled “Split to volumes, bytes” type in “500M” (no quotes) and click “OK”.
This will create a number of files (volumes) with up to the specified size each.
Upload chunks via FTP
After splitting the file into smaller chunks we now need to upload all of these chunks on to to the server. You would normally be doing this via FTP.
Combine chunks in server
Once the files have already been uploaded on to the server we will need to log on to server using SSH. Remember that you will first need to activate the SSH service.
For example, if you have split a file named
filename.pdf which was 450MB you will probably have now three files: filename.pdf.001 (500M), filename.pdf.002 (500M) and filename.pdf.003 (50M). In order to combine this files on the server we will need to type in the following command (in the directory were the files are stored):
cat filename.pdf.* > filename.pdf
This will take all the pieces and combine them into
