How to switch off NetBeans version control for a particular folder?
You can define a list of unversioned folders (such as /net).
Edit (or create) the file " <userdir>/config/Preferences/org/netbeans/modules/versioning.properties" and add an "unversionedFolders" property which can contain a semicolon-separated list of folders that should not be automatically scanned for versioning metadata.
unversionedFolders = /net
Please note that those folders will be excluded from all versioning operations, recursively.
