Study Notes
Hard Disk Drive Optimization
- Upgrading to a faster hard disk drive can significantly improve computer performance.
- Faster disk drives offer higher RPM (revolutions per minute) options: 7,200 RPM (minimum), 10,000 RPM, and 15,000 RPM.
- Solid-state drives (SSDs) and NVMe drives (nonvolatile memory express) offer faster performance without rotating disks.
- Upgrading the disk interface to PCIe can boost data transfer speed to 4,000 Mbps.
Disk Cleanup
- A full hard disk drive can have slower performance.
- Disk Cleanup app helps manage disks by removing unwanted files: empty Recycle Bin, delete temporary files, installation logs, offline files, and compress old files.
- Optimize Drives app defragments files on a hard disk drive, improving performance.
- Solid-state drives (SSDs) do not require defragmentation.
Check Disk
- Check Disk (chkdsk) utility verifies the integrity of a hard disk's file system.
- It can identify and fix errors like lost clusters, cross-linked files, orphaned files, and bad sectors.
- Run chkdsk with the /f switch to fix errors, /r to scan and fix bad sectors, and /? for help.
File Attributes
- File attributes are metadata that define file qualities in NTFS file system.
- Common attributes include: Archive (A), Compressed (C), Directory (D), Encrypted (E), Hidden (H), Not Content Indexed (I), Offline (O), Read-Only (R), System (S), and Temporary (T).
- FAT32 file system supports only R, H, S, and A attributes.
- Modify file attributes through file properties or Attrib command.
File Locations
- Important locations for system files:
- System files: %systemroot% or %windir% - usually C:\Windows
- Fonts: C:\Windows\Fonts
- Program files: %programfiles% - usually C:\Program Files, and C:\Program Files (x86) on 64-bit systems.
- User files: %userprofile% - usually C:\Users*username*
- Temporary files: %temp% or %tmp% - usually C:\Users*username*\AppData\Local\Temp
- %systemdrive% variable identifies the drive where Windows is installed.
File Extensions
- A complete filename includes file path plus file name.
- Extensions indicate file type, content, and creating/modifying program.
- FAT32 supports long filenames up to 255 characters, including spaces.
- NTFS supports Unicode filenames up to 255 characters, excluding /.
OneDrive Data Access
- Access OneDrive files through File Explorer, OneDrive folder (C:\Users*Username*\OneDrive), web browser (https://onedrive.live.com), and the OneDrive App.
- File Explorer provides right-click options like sharing, viewing online, version history, keeping files locally, and freeing up space.
- OneDrive allows recovery of deleted files from the Recycle Bin.
- The free version keeps files in the Recycle Bin for 3 to 30 days, while the Premium version keeps them for 93 days.
