You should never, EVER let a computer hard drive get completely full, EVER!

With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.

If it does, it's time for some hard drive housecleaning.

Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.

Have you emptied your Mac's Trash icon in the Dock?

If you use iPhoto or Aperture, both have its own trash that needs to be emptied, also.

If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.

If you are an iMovie/ Final Cut user, both apps have their own individual Trash location that needs to be emptied, too!

If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!

Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.

Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.

Visual studio for mac 2017 stability. STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!

Look through your Documents folder and delete any type of old useless type files like 'Read Me' type files.

Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.

Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.

To find other large files, download an app called Omni Disk Sweeper.

Also, Find Any File

Typically, iTunes and iPhoto libraries are the biggest users of HD space.

move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.

If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.

Moving iTunes library

Moving iPhoto library

Moving iMovie projects folder

A disclaimer,

Things to consider before moving your iPhoto Library Folder to a new or external location like an external hard drive.

If you make movies on any iDevices using iMovie for iOS, then transfer the video footage, the IOS version of iMovie saves the footage as a movie file in IPhoto for IOS and will automatically get transferred to iPhoto for the Mac when you upload the video from your iDevice. Download adobe indesign cs3 for mac free.

Newer versions of iMovie will work and link those video files found in your iPhoto Library on your Mac, but those links can be lost if you move your iPhoto library and you will not be able to relink that video afterwards as the current versions of iMovie seem to not have a relink option for the video portion of the files (ironically, current versions of iMovie HAVE the ability to re-link the audio files from the video footage, though (The inability to re-link the video files could be a possible bug or oversight in current versions iMovie).

The lost video links show up as 'blacked-out' video blocks with no content.

Before moving the iPhoto Library

If you make movies with iMovie using iPad or iPhone video then 'Consolidate' the files before you finish. This will gather (albeit by duplicating) all the relevant files in the project in one place. After consolidating/duplicating all of the audio and video footage to a seperate, independent location,it should be safe to move your iPhoto library.

The potential way to circumvent this issues maybe to try and import iPad and iPhoto video directly into iMovie which would be another solution.

Good Luck!

Do-It-Yourself Video Repair Tool (VRT) – MP4视频文件修复工具 – MP4 Repair

Our repair utility can repair and fix broken or damaged video files (MOV, MP4, 3GP, M4V) that do not play in your media player. Please check in our practical use cases if your video file issue is a mission for VRT .

What exactly means REPAIR? Repair means that only video and audio portions can be repaired that are not lost: On some of your corrupt files, it MAY NOT repair anything at all, on some files it MAY repair some video portions, and on some other files it MAY repair both video and audio portions (It fully depends on the grade of corruption).
Features:

• Repairs video files that are truncated, broken, corrupt or damaged
• Repairs video files that do not play in QuickTime or Windows Media player
• Repairs movies that were not finalized by the camera
• The repair does not depend on a valid/correct container format – the raw video and audio stream data is fully automatically reconstructed
• Supports non-broken reference movies for finding missing movie meta-data and parameters

Currently, our software can automatically repair damaged .mov, .mp4, m4v, or .3gp movie files (generally, all movie files based on QuickTime container format) that use one of the following codec formats:

• avc1 (H264/AVC, used by most digital cameras, HD video cameras, iPhone, etc.)
• hevc (H265, used by modern digital cameras, video cameras etc.)
• mp4v (H264/ISO, used by a few cameras)
• MPG2 / xdvc / xd5d / xd5e (MPEG-2 / XDCAM, used by Sony cameras)
• jpg (Motion JPEG,used by Panasonic cameras)
• icod (Apple Intermediate Codec, used by Final Cut)
• dvc / dvpp / dvhp (DVCPRO / DVCPRO HD, used by Panasonic cameras)
• apch / apcn / apcs / apco / ap4h (ProRes 4444/422/LT/HQ/Proxy, used by Final Cut)

Movies of the following cameras have been tested for correctness with our software (however we cannot test all camera models, and it generally works on most digital cameras):

Additionally, if our software doesn’t support your camera yet, we can add support for new video and audio encodings (our 10 years of experience in data recovery software helps us to develop something new).

System requirements:
Mac: OS X 10.6 or higher (requires Intel-based Mac, PowerPC not supported!)
PC: Windows Vista / 7 / 8 / 10 or higher
Supported camera formats: See above
DEMO version restriction: The repaired files are only half the size of the repaired movie files in full-mode! (e.g. if the DEMO version repairs 50 MB, the full version will repair 100 MB)

NOTE: For a successfull repair, always study the camera specific options listed in above table!

   a) PC: right-click the downloaded .zip file in Windows Explorer, and choose ‘Extract all…’.
   b) Mac: double-click the downloaded .zip file in the Mac Finder.
   Then go into the extracted folder.
2. Run the video repair tool:
   a) PC:
   Double-click the file ‘gs.exe’. On some systems, it just shows ‘gs‘. That’s the executable to run. NOTE: If you get a message (‘missing script file’), the .zip file hasn’t been extracted properly (check step 1). Important note for Windows 10 or higher: You may have to allow run (right-click on executable->Properties->allow)
   b) Mac:
   Double-click the file ‘gs.app‘. On some systems, it just shows ‘gs‘. That’s the executable to run. For Mac OS X 10.8 or higher: Right-click the app, and choose ‘Open’.
   If you get a message (‘missing script file’), the .zip file hasn’t been extracted properly (check step 1). Important note for OS X 10.8 or higher: Right-click on ‘mac_start’ and choose ‘Open With…->Terminal’. Also check our FAQs if this error does not go away.
3. Click on ‘Choose movie…’ and choose your broken movie.
4. Important: Click on ‘Choose reference movie’ and choose a non-broken (playable) movie of the same type (same camera settings). This is a required step if the broken movie is damaged (in most cases).
5. Click on ‘Scan’ to start the repair.
6. Wait until the repair has finished (the spinning wait cursor disappears). If the repair was successful, the found video clips can be found in the listbox. Click on one movie clip and choose ‘Preview’ to play back the repaired movie clip.
   NOTE: If the repaired movie appears very choppy, try to load another reference movie of the same camera.
   NOTE: Support for some cameras is experimental (see camera table at the top of this page how to enable experimental support for them!).
7. Options: If repair quality was not good enough, try to use different settings under ‘Options’:
   • Try ‘Overwrite existing codec information by reference file’ if your broken movie may contain invalid codec information, and the reference file codec information should be used instead.
   • Try ‘Enable AVC1 single mode‘ if repaired video is completely missing.
   • Try ‘No CTTS repair‘ if repaired if repaired video is there but choppy.
   • Try ‘Enable AAC detection‘ (for AAC audio) or ‘Enable PCM audio‘ (for PCM audio) if repaired audio is missing.

Repair 0 Byte Files Mac No Downloads

If your camera model isn’t listed above, or the repair tool doesn’t seem to work with your movie, please first try the ‘repair’ using a non-broken (playable) sample movie of your camera to find out if the program fully supports your camera:

1. Download the video repair tool DEMO version (.zip), and extract the downloaded archive by double-clicking it in the OS X Finder (Mac) or Windows Explorer (PC).
2. Run the video repair tool by double-clicking the application ‘gs.app’ (Mac) or ‘gs.exe’ (PC).
3. Click on ‘Choose movie…’ and choose a non-broken sample (playable) movie of your camera. Using a non-broken sample movie you can verify if the program fully supports your type of camera.
4. Click on ‘Scan’ and wait until the scan finished (spinning cursor disappears).
5. Click on ‘Preview’ to check if the movie could be ‘repaired’. If your sample file doesn’t repair, please send us a link to your non-broken sample movie (e.g. using some freely available online file sharing service such as www.wetransfer.com or ask us for our FTP), so we can add support for your camera to the repair tool.

Repair 0 Byte Files Mac No Download Version

This approach ensures that there are not two issues at the same time (program does not support your model, and damaged files does not contain any data). If it properly supports your camera model, but doesn’t work on the damaged file, the damaged file is too broken for a repair.

0 Bytes Free On Disk

After you sent us your sample movie, we’ll try adding support for your camera (this may take some weeks). All customer files are kept confidential.

Step 3: Your sample file repairs, but your broken movie doesn’t repair
If your sample movie correctly repairs (step 1), but your corrupt file doesn’t repair, we may check your corrupt file. Send us your corrupt movie (and one working sample movie of your camera) using an online file sharing service such as www.wetransfer.com (up to 2 GB files), www.wesendit.com (up to 5 GB files) or www.filemail.com (up to 30 GB files). After you sent us your truncated broken movie, we’ll examine it (this will take a few weeks). All customer files are kept confidential. Please only send small sample files (max. 100 MB), as we do not have a fast Internet connection here.
