If you recorded a Zoom meeting to your own computer and ended up with a file you cannot play, you are almost certainly looking at a recording that never finished converting. Zoom's support article is blunt about when that step happens: "After you end a Zoom meeting, your computer-recorded meeting will convert." Elsewhere Zoom phrases it slightly more cautiously — computer recordings "should automatically convert after they are ended" — and that gap between should and will is the whole reason this page exists.
This guide covers the recording type Zoom now calls a computer recording (the wording it uses in place of the older "local recording"). You need the Zoom desktop app, the computer you originally recorded on, and enough free disk space.
Before you start
Three conditions decide whether anything in this guide will work at all.
- It has to be a desktop recording. Zoom's FAQ states it directly: "Computer recording is only supported in the desktop app. The mobile-only supports cloud recording." If the meeting was recorded from a phone, there is nothing on a hard drive to convert.
- It has to be the same machine. Zoom's documentation says that "To play a computer recording, you must be accessing it from the same device on which it was recorded." Copying the Zoom folder to a second laptop and double-clicking there is not a workaround.
- Free disk space matters before you begin, not after. The conversion writes a new video file alongside what is already there, and low disk space is the one failure Zoom attaches an error code to.
On sizing, Zoom notes that "Recording screen sharing uses about 20MB of storage per hour, while recording video uses about 200MB of storage an hour," and immediately qualifies it: "This is an approximation, since the resolution and types of video or screen sharing content can affect the amount of storage used." Use those for planning free space, not as numbers you can hold Zoom to.
Step 1: Check whether it already converted
Open the Zoom desktop app and look at your list of saved recordings. Zoom's own tell: "Recordings not yet converted will display Convert next to the meeting topic." If there is no Convert button, the meeting converted normally and you are looking for a finished file, not a broken one.
That finished file is easy to miss, because Zoom does not name it after the meeting. Per Zoom's file-format article, "MP4: Audio/Video file that is named video[random number].mp4 by default." A large number of "my Zoom recording disappeared" cases are just this — an MP4 with a random number where a meeting title was expected.
Two neighbouring files confuse people the same way. M4A is "Audio-only file that is named audio[random number].m4a by default," and M3U is a "Playlist file to play all individual MP4 files (Windows only) that is named playback[random number].m3u by default." The M3U is a pointer, not a video — send the MP4 itself. Zoom also describes these as "some of the following file formats," so not every recording produces every file.
Step 2: Find the recording folder
Zoom's defaults, verbatim from its support article:
| Platform | Default folder |
|---|---|
| Windows | C:\Users\[Username]\Documents\Zoom |
| Mac | /Users/[Username]/Documents/Zoom |
| Linux | home/[Username]/Documents/Zoom |
If you changed the path at some point, Zoom's settings show the real one: "Under Local recording storage, locate the Storage location. The path listed next to the Storage location field is where your computer recordings are saved." The same paragraph carries a warning worth reading twice: "If the path shown isn't physically located within your device, such as a network drive, you might encounter issues."
Inside an unconverted recording's folder you will see the files Zoom names explicitly: "you should see double_click_to_convert_01.zoom and double_click_to_convert_02.zoom." Zoom's documentation gives you those filenames and the instruction to double-click the first one — it does not explain what the format is, so be sceptical of any guide that tells you confidently what a .zoom file contains internally.
Step 3: Convert from the Zoom desktop app
Before anything else, Zoom's own first-line advice: "In addition to the steps below, confirm that you are running the latest version of the Zoom desktop app."
Zoom documents two different routes to the recording list, and they do not match each other — which route you get depends on your client version, so try both rather than assuming one is wrong.
Route 1, from the troubleshooting article:
- "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."
Route 2, from the recording-management article:
- "Click the Home tab."
- "Below your daily list of meetings, click Open recordings."
- "You will be redirected to the Hub tab."
- "On the My files > Meeting recordings page, click the Computer recordings tab."
One caveat about this list, in Zoom's words: "Removing items from this list doesn't remove the actual recording files on your computer. As a result, this list may not show all of your computer recordings." A recording missing from the app is not necessarily a recording missing from the disk — check the folder from Step 2 before concluding it is gone.
Step 4: Convert the file directly
If double-clicking double_click_to_convert_01.zoom does nothing, or Windows asks you which app to use, Zoom documents how to point it at the converter by hand.
On Windows, when prompted with "How do you want to open this file": click More apps, then Browse, then go to C:/Users/(PC username)/AppData/Roaming/Zoom/bin, select zTscoder.exe, optionally tick "Always use this app to open .zoom files," and click OK.
On macOS, open Applications, right-click zoom.us, choose Show Content package, open Contents then Frameworks, copy Transcode, paste it into Applications, then right-click double_click_to_convert_01.zoom, choose Get Info, and set Open with to Transcode.
Two limits to flag honestly. Zoom documents these manual steps for Windows and macOS only — there is no published Linux procedure, even though Linux has a documented default folder. And Zoom describes zTscoder.exe as something you locate inside your existing installation; despite what some guides claim, its support articles do not present it as a standalone download.
Try it right here
Runs in your browser. Your file is not uploaded anywhere.
Be clear about what that converter is for: it will not open a .zoom file — only Zoom's own converter is documented to do that. It handles the step after. Once you have a playable video and need it in an MP4 container for an LMS or a colleague who cannot open QuickTime files, it does the container swap inside your browser, with nothing uploaded anywhere — which matters for meeting recordings more than for most files. If it also needs to be smaller, how to compress a video without losing quality covers which settings actually move the number.
Common mistakes
- Renaming the files mid-conversion. Zoom is explicit: "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." The urge to tidy up filenames before uploading is exactly the wrong instinct here. Rename the finished MP4 instead.
- Closing the laptop. "If you close your laptop or turn off your computer while the recording is converting, it will stop the conversion process." Zoom does not document whether an interrupted conversion can be resumed, so do not count on it.
- Recording to an external drive or NAS. Zoom's FAQ answers this one under how to keep recordings from being damaged: "Do not use external or network storage for computer recordings; for example, an external hard drive or network-attached storage. These storage methods can result in data loss." This pairs with the failure Zoom lists as "Invalid working path/folder (sometimes, an invalid network connection may appear with this warning too)" — the fix being to "Change the recording location in your Zoom client and make sure it is a valid path string/folder."
- Running out of disk space. This is the one scenario Zoom gives a code for: "You may have low disk space on your computer at that time. [Error Code 614]" and the fix is to "Check your disk space and try and free up some space if it is low." Zoom binds 614 to low disk space specifically, so treat it as a storage message rather than a generic conversion failure.
- Trusting the unofficial "record a new meeting over it" trick. Several popular guides describe starting a fresh meeting to force a stuck file to convert. That procedure appears nowhere in Zoom's support articles — it is a community workaround, not a documented one, and Zoom has already warned that touching those files mid-conversion can corrupt them.
FAQ
Why is my Zoom recording a .zoom file instead of an MP4?
Because the meeting never reached the point where Zoom converts it. Conversion is triggered by the meeting ending, so a crash, a forced quit, a power loss or a closed laptop leaves you at double_click_to_convert_01.zoom. Double-click that file, or use the Convert button in the desktop app.
Where does Zoom save recordings by default?
C:\Users\[Username]\Documents\Zoom on Windows, /Users/[Username]/Documents/Zoom on Mac, home/[Username]/Documents/Zoom on Linux. If someone changed it, the real path is shown next to Storage location in Zoom's local recording settings.
What does Zoom Error Code 614 mean? Zoom lists it under low disk space: "You may have low disk space on your computer at that time. [Error Code 614]" Free up space on the drive holding your recording folder and try the conversion again.
Can I convert a Zoom recording on a different computer? No. Zoom states that to play a computer recording "you must be accessing it from the same device on which it was recorded." Convert on the original machine, then move the resulting MP4 wherever you like.
Why can't my colleague open the .m3u file I sent?
Because an M3U is a playlist, not a video — Zoom describes it as a "Playlist file to play all individual MP4 files (Windows only)." Send the video[random number].mp4 files themselves.
Does a Zoom recording need converting if it was recorded to the cloud? Zoom lists MP4 among the formats that cloud recordings are saved in, but its documentation does not state whether cloud recordings skip a conversion step. Check the official documentation for how your account's cloud recordings are processed.
