A file called double_click_to_convert_01.zoom sitting in your Zoom folder means the recording is there but the conversion step never finished. The meeting was captured; what is missing is the pass that turns Zoom's working files into the MP4 and M4A you can actually open.
The file name is the instruction, and it usually works. When it does not, Zoom documents a manual route on both Windows and macOS — and one detail in that documentation is inconsistent in a way worth knowing before you start.
What this file actually is
Zoom ties conversion to one specific moment. Its troubleshooting article opens with it: "After you end a Zoom meeting, your computer-recorded meeting will convert." The article on starting a computer recording says the same thing with the outcome attached: "After the meeting has ended, Zoom will convert the recording so you can access the files. Once the conversion process is complete, the folder containing the recording files will open."
Note the wording elsewhere is softer. Zoom's page on managing computer recordings says recordings "should automatically convert after they are ended" — should, not will. That gap is the whole reason .zoom files exist on people's disks.
So anything that stops a meeting from ending cleanly, or interrupts the pass that follows, leaves you exactly here. Zoom never describes what is inside a .zoom file; the only label it gives them is "unconverted recording files," which appears as a desktop setting named Keep unconverted recording files for troubleshooting. There is no documented way to open one in another player.
The fastest fix: double-click, from the recording folder
First confirm you are in the right folder. Zoom's default locations are:
Windows: C:\Users\[Username]\Documents\Zoom
Mac: /Users/[Username]/Documents/ZoomZoom also lists a Linux default, but writes it two different ways across its own pages, so check the Storage location field in your client's recording settings rather than trusting a printed path.
Inside the meeting's subfolder, Zoom describes what you should see: "Once you have confirmed the computer recording file location, you should see double_click_to_convert_01.zoom and double_click_to_convert_02.zoom. You can manually convert the recording when you double-click on file double_click_to_convert_01.zoom."
Here is the inconsistency. That article (KB0061761) tells you to double-click _01 only. A different Zoom article on missing recordings (KB0083769) says: "Double-click double_click_to_convert_01.zoom and double_click_to_convert_02.zoom to manually start conversion." Two official pages, two instructions. Start with _01, since both pages agree on it; if nothing appears afterwards, the second page's advice to double-click _02 as well is also Zoom's own.
There is a button route too. Zoom's troubleshooting steps are: sign in to the Zoom desktop app, click the Meetings tab, click the Recorded tab, select the meeting topic with the computer recording, click Convert. An unconverted item is easy to spot — "Recordings not yet converted will display Convert next to the meeting topic." Other Zoom pages route you through the Home tab or the Hub tab instead, so the exact menu names depend on your client version. Before any of this, Zoom's own first suggestion is to "confirm that you are running the latest version of the Zoom desktop app."
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
To be clear about what that converter does: it will not open a .zoom file — only Zoom's converter is documented to do that. It handles the step after, when you have a playable recording that needs to be in an MP4 container for an LMS, a colleague, or an editor. It runs in your browser, so a meeting recording never leaves your machine. The full set is at all Clapr tools, and converting a Zoom recording to MP4 covers the normal, non-broken path.
If double-clicking does nothing
Zoom's instructions for this start with: "If nothing happens or you get a prompt asking you how to open the file, please follow these steps."
Windows. When prompted with how you want to open this file, click More apps, then Browse, then go to Local Disk and follow the path C:/Users/(PC username)/AppData/Roaming/Zoom/bin. Select zTscoder.exe and make sure it is shown in the dialog. You can optionally tick "Always use this app to open .zoom files," then click OK and wait for the conversion to complete.
macOS. From your desktop, click Go then Applications. Find zoom.us, right-click the folder and select Show Content package. Open Contents, then Frameworks. Find Transcode, right-click and copy it, then paste it into the Applications folder in Finder. Go back to the recording file, right-click double_click_to_convert_01.zoom, click Get Info, and set Open with to Transcode.
Zoom documents these two platforms only. There is no official manual-conversion procedure for Linux.
Other causes, in order of likelihood
Low disk space. This is the one case Zoom attaches an error code to: "You may have low disk space on your computer at that time. [Error Code 614]" The fix given is exactly what it sounds like — "Check your disk space and try and free up some space if it is low." Code 614 is documented only for this situation, not as a general conversion failure code.
An invalid recording path. Zoom lists "Invalid working path/folder (sometimes, an invalid network connection may appear with this warning too)" and says to change the recording location in your Zoom client to a valid path. Related: Zoom warns that setting the default location to a cloud syncing folder "such as Dropbox, Google Drive, or One Drive," an external drive, or network storage "may cause issues with saving and converting the computer recording."
The conversion was interrupted. Zoom: "If you close your laptop or turn off your computer while the recording is converting, it will stop the conversion process." The recording article puts it harder — restarting, shutting down, putting the hard disk to sleep, or closing your laptop will interrupt conversion, and the files "could become corrupted and non-recoverable."
The files were renamed mid-conversion. Counterintuitive but documented: "If you change the name of the double_click_to_convert.zoom file(s) while the recorded meeting is converting, it may corrupt the file and not convert correctly." Rename after, not during. Zoom does recommend renaming the finished file to something unique, and specifically advises against using the words Zoom, Personal Meeting Room, or My Meeting.
You are on the wrong machine. Computer recordings must be accessed "from the same device on which it was recorded." And if the file is gone, Zoom is direct about it: "Local recordings exist only on the computer where they were created. Zoom does not retain a copy and cannot recover a lost local recording."
How to tell it worked
The folder containing the recording files opens on its own when conversion completes. You should end up with a video file named video[random number].mp4 and an audio-only file named audio[random number].m4a by default — one Zoom page writes those placeholders as video[number].mp4 and audio[number].m4a, but the pattern is the same. The file will not be named after your meeting.
Two popular fixes Zoom does not document
Both of these are everywhere in search results, and neither appears in Zoom's documentation: downloading zTscoder.exe as a standalone tool, and the trick of starting a new meeting, recording briefly, then swapping the old .zoom files in to trigger conversion. Treat both as community workarounds, not official procedure — the second one involves renaming and replacing files mid-conversion, which is the exact thing Zoom warns can corrupt them.
FAQ
Should I double-click both _01 and _02?
Zoom's two articles disagree. The troubleshooting page says double-click _01; the missing-recordings page says double-click both. Start with _01, and if nothing happens, _02 is also officially sanctioned.
What does Error Code 614 mean? Low disk space at the time of conversion. Zoom documents 614 for that case only; free up space and convert again.
Can I open a .zoom file in VLC or another player?
Zoom does not document any way to do that. Its own converter — zTscoder.exe on Windows, Transcode on macOS — is the only route described.
How long does converting take? Zoom gives no timing for computer-recording conversion. The "about twice the recorded duration" figure you may have seen applies to cloud recording processing, not this. Check the official documentation if you need a figure.
What format do I end up with? MP4 for audio/video and M4A for audio-only. Zoom does not state which codecs are inside, so if a specific editor refuses the file, converting the container is the practical next step.
