Derived files

Note that derived files do not belong in repositories, instead keep the source code that you used to create the derived files in the repository.

Binary files in SVN repositories

Subversion repositories are most useful for : source code , although binary files can be stored in them, most of the benefits that subversion provides are irrelevant for binary files. This is because source code repository operation is based on the differences between files, for binary files the difference is not meaningful.

• subversion is simply the wrong tool for managing binary files.

THINK before you commit

Once a file is committed to a subversion repository, it cannot be removed (without lengthy and painful efforts involving dumping the entire history of the repository into a file , and then replaying the entire history of the repository commit-by-commit to create a new one).
