Hello! For everyone having issues with the nextcloud desktop app while uploading big files I found a solution for it. After reading the docs and forums multiple times I finally found a solution. Of course you have to first modify your nextcloud instance to accept big files. Then you need to check [the docs of the desktop app](https://docs.nextcloud.com/desktop/latest/advancedusage.html) and modify the `maxChunkSize` parameter. After I reduced it to 50MB I was able to upload big files. I don’t know why this option was setted by default at 5GB. These are the sources that I followed. [nextcloud set up](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/big_file_upload_configuration.html#adjust-chunk-size-on-nextcloud-side) **This configuration only works with web uploads** [Another configuration parameter](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html#files-chunked-upload-max-size) **This is for desktop apps** [found in here](https://help.nextcloud.com/t/documentation-inconsistency-how-to-set-chunk-size/207989) Good luck! Edit: Forgot to mention that the file upload was tested with a 10GB and 16GB File. both of them work, as I setted up the limit at 16GB it will not accept bigger files. ---
