After downloading the 4.9 upgrade I get the error of Insufficient storage space. I have HA installed and some small tools but nothing big. I haven’t started the upgrade yet. Anyone else seen this? ![IMG_6678](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/6/6771d34ab49d5923d82652e13bbd8788f052b4b3.jpeg) ---

Sorry to spell it out like this, but the search function is there for a reason. This has been discussed plenty of times before, and there’s no shortage of advice on what to do. Hopefully, some of the older threads will point you in the right direction. See this one by @MichaelLearnsToCode, and knock yourself out. 🤓 > [@NSPanel Pro v4.1.0 Release: New Features & Enhancements](https://forum.ewelink.cc/t/nspanel-pro-v4-1-0-release-new-features-enhancements/206443/178): > > please refer to [NSPanel Pro V4.0.12 impossible to complete update - #3 by MichaelLearnsToCode](https://forum.ewelink.cc/t/nspanel-pro-v4-0-12-impossible-to-complete-update/206373/3) for how to clear the cache of `NSPanelPro` App. ---

Whilst I was searching for someone that had had this specific problem with 4.9 and didn’t see that so posted.. I also can cancel out of the error and the unit still works as normal so didn’t know if it was exactly the same… this also I didn’t see in my search.. but thank you for being sorry for spelling it out to me.. I’ll try harder next time.. ---

I do not know if it helps, but in my case the logs folder is full with these files: ![photo_2026-09-26_09-29-33](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/c/c019d0293fef2d80d9d844bdc05cf692ea19490d.jpeg) ---

> [@kraots94](#): > > if it helps Absolutely, it should help. Clearing out temporary files like logs will definitely reclaim some space. Let’s be honest, the NSPanel Pro isn’t exactly blessed with generous storage. Then there’s F-Droid, enthusiastically scattering files everywhere like a digital confetti cannon. On a phone, who cares in most cases. On the NSPP, though, it becomes a problem. ---

Thank you very much for your feedback. We apologize for any inconvenience this may have caused. Deleting this 2 GB log file will not affect system operation. In addition to deleting it manually, you can also keep our app running; the app is expected to automatically delete the file on September 27. A 2 GB log file is indeed abnormal. Our project currently uses a third-party Android library as the logging tool, and this does not match the logging configuration we set for it. This is very unusual, and it is the first time we have encountered this issue despite using the library for so long. Next, we will analyze the source code of this third-party library or develop our own logging tool to resolve the problem. After the 2 GB log file is deleted, we would also appreciate it if you could take a moment to submit the panel logs (Settings → About → Feedback) and provide the device ID. This will give us more information to analyze the issue. Thank you for your cooperation. ---

Sadly I wiped out with factory reset the device and updated to the last firmware version. If this problem arises again i will send feedback. ---

My log files are not that big… Also how do you delete them? I tried clicking on one and got asked for a password which I don’t remember setting.. ![IMG_6691](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/c/c21897333dec6eecb968ea842efab7bb94a72281.jpeg) ![IMG_6692](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/7/7d8b02fe2e7ad2481432b6e695440e72bf093d31.jpeg) ---

> [@mark20](#): > > I don’t remember setting You didn’t set this password yourself. It’s the password for the built-in FileManagement editing mode. The password is **smatek@123**. This password was posted on the official eWeLink Forum and should work, although I can’t guarantee it will work with your particular firmware version. According to eWeLink Forum, you can safely delete the old OTA files from: ` /data/data/com.eWeLinkControlPanel/files/ota/` ---

Thank you, @jam3 , for the detailed feedback. This was a known issue in an older version. @kraots94 @mark20 Could you please confirm whether the file has now been deleted successfully and whether the NSPanel Pro is running normally again? If this issue occurs again in a newer version, please send me a message and provide the device ID. I’ll check it as soon as possible. ---

Hello, I deleted the file in `/data/data/com.eWeLinkControlPanel/files/ota/` (there was only one file) and restarted the update, but I am still getting the “memory full” message. What should I do? Thanks. Original français : Bonjour, J’ai procédé à la suppression du fichier dans `/data/data/com.eWeLinkControlPanel/files/ota/` (il n’y avait qu’un seul fichier), j’ai relancé la mise à jour, mais j’ai encore le message de mémoire pleine. Que dois-je faire ? merci ---

Hi, have you already downloaded **Fossify File Manager**? If not, you can refer to the instructions here. > [@NSPanel Pro V4.0.12 impossible to complete update](https://forum.ewelink.cc/t/nspanel-pro-v4-0-12-impossible-to-complete-update/206373/3): > > Hi, sorry for the issue. There is a bug in previous and current v4.0.x firmware which doesn’t delete used OTA files. So after several update, these unnecessary OTA files have occupied a large amount of storage space. You can follow the steps below to clear these OTA files. As a side effect, you will need to reconfigure your NSPanel Pro after that. Note: Reconfigure only involves Language Setting, Country Setting, Custom Wallpaper, Custom Ringtone. Zigbee network, Wi-Fi etc., remain intact. … If you’ve already installed it, you can check how much storage space each folder is using. You can also send me screenshots, and I can help confirm which files or folders can be safely deleted. If you’re not sure how to check the storage usage, you can send me the device ID separately. I’ll try to look into the relevant information and confirm which content can be removed. ---

Wouldn’t it be better to have it delete older downloaded updates after an updates? ---

Hi, just to confirm, have you installed any additional apps on your NSPanel Pro? You can check the storage usage of each app under **Advanced Settings \> Apps** and see whether any app is taking up an unusually large amount of space. ---

Hi, based on your screenshot, it looks like **F-Droid is using an unusually large amount of storage**. Have you downloaded multiple apps through F-Droid? If there’s no important data stored in F-Droid, you can try clearing its cache/data and see whether that frees up some space.
