A user cannot save a 2 GB file to a file server because there is insufficient space. What should the technician do FIRST to resolve this?

To resolve the issue of a user being unable to save a 2 GB file due to insufficient space on a file server, the most appropriate first step is to free enough disk space to hold the largest file's uncompressed size. This action addresses the immediate problem directly by ensuring that there is enough available space on the server for the file being saved.

In many cases, disk space limitations are the primary cause of failure when attempting to save large files. By clearing up space—such as deleting unnecessary files, archiving old data, or moving files to another storage location—the technician can enable the user to successfully save the file.

The other options, while they may offer some benefits in a broader context, do not directly address the issue of insufficient disk space. Reducing system CPU and memory requirements does not contribute to addressing file storage capacity. Similarly, encrypting the file system can enhance security but will not resolve space issues and may, in fact, require additional storage space. Finally, installing more memory would not be effective in this scenario as the restriction on saving the file is tied to storage capacity, not memory limitations. Therefore, the focus on freeing up disk space is the most logical and effective first step in resolving the user's inability to save the file
