How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you

File.getCanonicalPath()is, at least with my setup, not a reliable way to get the real filename. I wrote a small class which repeatedly prints the result ofFile.getCanonicalPath()to the Eclipse console. While the program runs, renaming the file "abc.txt" to "Abc.txt" results ingetCanonicalPath()still returning "abc.txt", until I restart the program / JVM. My setup is JDK 6u45 and Windows 10. I had to use a solution based on the expressionArrayUtils.contains( parentFile.list(), realFileName ).
