All kinds of files could be hidden files, such as a. In Unix, there is always a “.” in front of hidden file names and they won’t be displayed until you manually change the system to view hidden files. MacOS has almost the same contents as UNIX but the macOS has a “desktop environment” which helped it become the world’s second most popular operating system. However, if you don’t know how to do show hidden files and folders, you won’t be able to deal with these issues.įirst, let me tell you what files are hidden and why are they hidden on your Mac.īoth macOS and linux are based on the UNIX operating system. Some hidden files also take up a lot of space on your hard disk. Some experienced or advanced users know that when you have a problem with an app, you might need to remove a preference file or find logs to help you fix the problem. In this case, you should learn how to show hidden files and folders. Sometimes just out of curiosity or perhaps to locate some hidden folder for troubleshooting purposes. However, there may be occasions where you need to locate certain hidden files. You might not know it, but there are thousands of hidden files and folders on your computer that you shouldn’t disturb or modify. There are many reasons why you might want to look at hidden files or folders on your Mac. Quite a number of various specific-purpose "instruments" built with this configuration from loose-parts monitoring to neutron-noise systems looking for things like inner liner vibration/movement, etc. Fairly shortly after it was replaced by a Cyber 76.after only a couple years with the latter, I moved on to the consulting gig and the other end of embedded/standalone systems, mostly around the M6809E running Forth. Other than the commercial timeshare still in Philly, I think it well may have been the last one in a production environment. The Philco was already in the process of being retired when I arrived but it took over two years to get the CDC 6600 installed and able to run all the needed codes before could pull the plug on the old Philco. Fortran II and assembler for it running the proprietary versions of the nuclear design codes from Bettis for a commercial nuclear power vendor. We're not that far apart, then although I predate you by probably about 10 years or so.first mainframe was a Philco 2000 the class scientific computing machine of its era - no disk or durm, but 27(!) 7-track tape drives. The problem I have is that I have the app working for Windows but running aground trying to resolve this issue on the Mac.The danger is that if I go that far it might be easier for me to write an Apple native app. I intend to investigate how Apple Swift / Xcode handles hidden files.I would love to be able to replicate this in code. There is a Mac keyboard combo of Cmd Shift + which reveals / hides System / Hidden files.My fear is that my code may need to be hardcoded for every brand of camera. I know in Sony's case, if the AVF_INFO is missing the camera will give you a message. No doubt Canon and Nikon and Fuji will all use similar techniques to keep their SD card housekeeping directories away from casual misuse. Sony have obviously found a way to flag a folder as hidden (AVF_INFO). you can see that I have already removed all the dot and dot dot dirs, everything beginning with a dot. which so far has not revealed a magic option. Mac documentation for this command is extremely sparse and refers to general linux to get more info. I have started to look at the ls command.so my app will fail at some stage when it tries to take inappropriate actions on these directories. so other than hard coding this directory name, I cannot exclude it from a dir list. the attributes function returns a value of NaN for this directory. but it is included in the contents of a Dir command. Again, this is invisible, by default in most scenarios. It contains a database of the images and video files stored on the SD card and allows the Sony cameras display thumnnails and other key features on a modern digital camera. This is a hidden directory created by Sony when they format Sd cards in their cameras. and subsequently encounter uncontrollable error conditions. I do not want to copy this dir by mistake, or include this dir for a user to select. I just need to make sure that I can remove it from my Dir list (eg. I assume this is both a Sytem file and perhaps hidden file.
