Commander OneĬommander One ranks with Path Finder as a fully-developed, mature Finder alternative. You’ll find dual pane browsing and a few advanced tools here, too, but in a simpler package. The many panes and windows are gone, and the user interface is trimmed down to focus on moving and copying files. You can even open a Terminal window in one of the panes for your on-the-spot command line needs. seems much better (faster, easier, etc) we just have one issue weve found. Slide up the extra panes on the bottom, and you can see detailed file info, attributes, hex code, preview data, permissions, and more. A virtual file system (VFS) or virtual filesystem switch is an abstraction. It will also tell you more than you ever wanted to know about your data. Path Finder brings a dual pane interface and dozens of advanced tools. It “replaces” Finder in the sense that, if you love Path Finder, you won’t need to use the vanilla Finder again. Instead, it runs simultaneously, providing advanced functionality and new tools in a different application. Path Finder doesn’t modify or replace the built-in Finder program. It might be called a “Finder replacement,” but that’s not as drastic as it sounds. For the latest sources, please refer to the above project page.Path Finder is the elder statesman of Finder alternative applications and my personal favorite. It is a open source Java Maven project and avaiable on GitHub/xattrjįor reference, I post the interesting source pieces here. I have created a JNI wrapper for accessing the extended attributes now directly over the C-API. Is there a better way to access the extended attributes on HFS+ with Java? What is a fast way to work with the extended attributes on OS X with Java? Using this in java gives me an additional overhead of creating a process, parsing the output which makes it even a bit slower. A little delay is clearly visible and thus I guess the tool is not that fast. If I run it, the lines appear "fast" after each other, but I would expect to show me the output immediately within milliseconds. To prove that it is not a Java issue but the tool itself, I have created a simple bash script to use the xattr tool on several files which have my custom attribute: FILES=/Users/IsNull/Pictures/ (Writing is damn slow, but more importantly also reading an attribute is slow) It turned out, that the xattr tool works quite slow. (Recalculation of the file hash is faster, how ironic! I am testing on a Mac BookPro Retina, with an SSD.) My implementation works, but it is very slow. In oder to come by this java limitation, I decided to use the xattr commandline tool present on OSX and use it with Javas Process handling to read the output from it. How to store extended file attributes on OS X with Java? Albeit, I do not understand why especially the HFS+ filesystem is not supported - it is one of the leading formats for metadata? (see related Question - which does not provide any solution) Sadly, UserDefinedFileAttributeView does not work on HFS+. I already implemented it, and you can find the current source here: archimedesJ.io.metadataĪt a first glance, Java 1.7 offers with the UserDefinedFileAttributeView a nice way to handle metadata. My idea is now to calculate the hash just once and store it in the files metadata (extended attributes) to boost performance on filesystems which support extended file attributes. In order to update and import mediafiles, I need to (re)create the file hashes of all files in my library. I developed a fast file-hash-id algorithm based on a tradeoff between accuracy and performance, but fast is not always fast enough. Once imported, I store the path and the hash in my database. The user shall be able to move the files around, so I do NOT want to rely on any file path. I am working on a platform in-depended media database written in java where the media files are identified by a file hash.
