7-Zip File Manager. 7z.exe is the command-line tool. 7zFM.exe is the window you browse archives in.

What you need to know

This is the 7-Zip window. 7z.exe on the command line is a sibling tool, not a second product URL.

7zFM.exe is 7-Zip File Manager. CPU during a 7z ultra compress is the algorithm, not Defender by default. MsMpEng may still scan the output when the file lands.

Safe?: Yes, from 7-Zip
High CPU?: You are compressing or testing an archive
Same as 7z.exe?: No. That is the CLI

Feex says

If 7zFM is busy and you started a solid 7z, I would let it finish. Ending it leaves a truncated archive. That is not how you save the disk.

What is 7zFM.exe?

7zFM.exe is the 7-Zip File Manager GUI. 7z.exe is the console compressor. 7zG.exe is a GUI helper for progress dialogs. One product, three tools.

What does it do?

It lists archives, extracts, and starts compress jobs. Explorer context-menu extracts often call 7zG.exe, so you may not see 7zFM at all.

Why is it running?

You opened 7-Zip or a file association launched the manager. A 7zFM.exe from a "7zip pro" ad site is not Igor Pavlov's build.

Is it safe?

Usually safe

A 7-Zip.org build under Program Files\7-Zip is the real manager. The publisher shows as Igor Pavlov. Other publishers need a second look.

A legitimate copy normally runs from:

C:\Program Files\7-Zip\7zFM.exe

Sibling tools: 7z.exe, 7zG.exe
Official site is 7-zip.org
Context menu may use 7zG instead

Can I end it?

Aborts the archive job

Ending 7zFM.exe during compress leaves a bad archive. Let the dialog finish or cancel from 7-Zip.

Can I remove it?

Uninstall 7-Zip

Use Settings > Apps. Do not delete only 7zFM.exe if you still want the context menu tools.

Should it start with Windows?

7-Zip should not start with Windows. A Startup 7zFM is unexpected.

Normal resource behavior

These are contextual labels, not universal averages.

CPU: High during LZMA2 ultra, by design
Memory: Dictionary size settings
Disk: Read source, write archive
Network: None unless the path is remote

Common problems

Defender scans the new archive

MsMpEng can spike after 7-Zip writes a large file. That is the scanner, not 7zFM leaking.

People download 7-Zip from ad networks

The official domain is 7-zip.org. Other domains add junk.

Troubleshooting

Diagnose before you change anything destructive.

Watch whether 7zG.exe is the busy helper

A context-menu extract may not show 7zFM at all.

Lower dictionary size if the PC pages

That is a 7-Zip setting, not a Windows service.
