First, click the Preferences button in the upper right corner of the SpiderOak application window, then select the 'Back Up' tab.
To exclude files or folders with a certain word or phrase in the filename, you will need to set a wild card exclusion. When you are selecting a wildcard to exclude certain directories, you must make certain that you include an asterisk (*) where appropriate.
For example, to exclude all files or folders that END with the phrase 'stuff', add the wildcard exclusion:
If you type this in 'Exclude files matching wildcard' field, this tells SpiderOak to exclude all files that end with the phrase 'stuff' regardless of what other text is in front of the file. If you type this in the 'Exclude folders matching wildcard' field, SpiderOak will exclude all folders ending with 'stuff'
To exclude a file or folder that has 'stuff' anywhere in its file name, enter the exclusion: stuff To exclude a particular type of file, such as temp files, type an asterisk followed by the file type in the 'Exclude files' field. To exclude temp files, you would enter the wild card exclusion: *.tmp If you do not include any asterisks in your wildcard, SpiderOak will only exclude those files and directories which exactly match what you have entered.
