I’ll type a search term like logo and the menu will suggest “Name matches: logo”. By selecting that option, I’m kicking off a search for files with the word “logo” in the name. Google Desktop was a computer program with desktop search capabilities, created by Google for Linux, Apple Mac OS X, and Microsoft Windows systems. It allowed text searches of a user's email messages, computer files, music, photos, chats, Web pages viewed, and the ability to display 'Google Gadgets' on the user's desktop in a Sidebar.

Show or hide filename extensions on Mac. A filename extension appears at the end of some filenames, and looks like a period followed by a few letters or words (for example,.jpg). A file’s filename extension shows what type of file it is and what apps can open it.

Apple File System (APFS)

Apple File System (APFS), the default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. While APFS is optimized for the Flash/SSD storage used in recent Mac computers, it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. macOS 10.13 or later supports APFS for both bootable and data volumes.

APFS allocates disk space within a container on demand. The disk’s free space is shared and can be allocated to any of the individual volumes in the container as needed. If desired, you can specify reserve and quota sizes for each volume. Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all the volumes in the container.

Mac Os Search For File Type

Choose one of the following APFS formats for Mac computers using macOS 10.13 or later.

  • APFS: Uses the APFS format.

  • APFS (Encrypted): Uses the APFS format and encrypts the volume.

  • APFS (Case-sensitive): Uses the APFS format and is case-sensitive to file and folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.

  • APFS (Case-sensitive, Encrypted): Uses the APFS format, is case-sensitive to file and folder names, and encrypts the volume. For example, folders named “Homework” and “HOMEWORK” are two different folders.

You can easily add or delete volumes in APFS containers. Each volume within an APFS container can have its own APFS format—APFS, APFS (Encrypted), APFS (Case-sensitive), or APFS (Case-sensitive, Encrypted).

Mac OS Extended

Choose one of the following Mac OS Extended file system formats for compatibility with Mac computers using macOS 10.12 or earlier.

  • Mac OS Extended (Journaled): Uses the Mac format (Journaled HFS Plus) to protect the integrity of the hierarchical file system.

  • Mac OS Extended (Journaled, Encrypted): Uses the Mac format, requires a password, and encrypts the partition.

  • Mac OS Extended (Case-sensitive, Journaled): Uses the Mac format and is case-sensitive to folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.

  • Mac OS Extended (Case-sensitive, Journaled, Encrypted): Uses the Mac format, is case-sensitive to folder names, requires a password, and encrypts the partition.

Windows-compatible formats

Choose one of the following Windows-compatible file system formats if you are formatting a disk to use with Windows.

A: Some Mac files have a 'Creator' and 'Type' identifier rather than a file extension. This comes from Mac OS 9 and previous versions of the Mac OS, in which most Macintosh files did not have file extensions. In Mac OS X, nearly all filenames include an extension, though files with no extension can still be opened.

If the associated program for the 'extensionless' file is installed, Mac OS X should automatically open the file with the correct program. If the application is not available, you may get an error saying the file cannot be opened. If this is the case, you may try to drag the file to an application you think might open the file. For example, if the file is a text file, try dragging it to TextEdit. If you think the file is a picture, try opening it in Preview. If it is an audio or video clip, try dragging the file to QuickTime Player to see if it will open.

Sometimes it is difficult to determine the file type of a file with no extension, but there are some programs that will show you the Creator and Type information, which can be helpful. For example, if the Creator is listed as 'SIT!,' you may be able to guess that the file is a StuffIt file, and therefore can be opened with StuffIt Expander.

Two programs that allow you to view the Type and Creator information of files include NameCleaner and FileType. These programs also let you alter the Creator and Type information, which usually should not be changed. If the Creator and Type information is modified incorrectly, no programs will recognize the file.

If you have tried the steps above and still cannot open the file, it is possible the file belongs to a Windows program and is just missing a file extension. You may want to transfer the file to a Windows-based computer to see if a Windows program will open it.
