The correct answer is A. Free enough disk space to hold the largest file's uncompressed size. Enabling NTFS compression requires free disk space equal to the largest file's uncompressed size so the OS has room to process the file during conversion.
Question
A user cannot save a 2 GB file to a file server. A technician determines that permissions are correct and the file system has 10 MB of available space for new files. The technician wants to enable compression as a short-term fix. Which of the following should the technician do FIRST?
Options
- AFree enough disk space to hold the largest file's uncompressed size
- BDecrease the amount of system CPU and memory requirements
- CEncrypt the file system on the server
- DInstall at least enough memory to hold the largest file's uncompressed size

Why each option
Enabling NTFS compression requires free disk space equal to the largest file's uncompressed size so the OS has room to process the file during conversion.
When the NTFS compression process runs on a file, the operating system must write the newly compressed version alongside the original before swapping them, which temporarily requires free space equivalent to the uncompressed file size. With only 10 MB of free space on the volume, attempting to compress a 2 GB file would fail without first freeing enough space to accommodate that temporary working copy.
Adjusting CPU and memory usage is unrelated to enabling disk compression; compression increases CPU overhead during file operations and does not require memory to be freed first.
Encrypting the file system is a separate, unrelated operation that would not resolve the insufficient disk space issue and is not a prerequisite for compression.
System RAM is not a prerequisite for enabling NTFS compression; the compression process is handled at the file system driver level and does not require installing additional memory equal to the file size.
