You can compress the required file to a zip (or rar) file by setting the maximum file size so that it is split. This means that you will always have a program to get the source file back.
Some options:
- HJSplit is free and portable (size = 300 KB) and does not need to be installed.
- There is an older version of the Goetz File Splitter command line version , it is best to plan to run batch scripts to split many files.
- 7-Zip is another free open source program that allows you to split (with or without compression) and combine files, either through the graphical interface (right-click on a file> Split file ...> select a size) or in command line.
- Total Commander does this as well (Files> Split File ...).
