Method for managing filesystem elements, method for setting up user access to a storage system, system and non-transitory computer readable storage medium

A method of managing filesystem elements between a user device and a network, the method comprising:

• receiving, from the user device connected to the network, a request related to a filesystem element operation over the network, the user device comprising a local metadata file and a network encryption key, and the network comprising an encrypted network metadata file;
• performing the filesystem element operation;
• updating the local metadata file based on the filesystem element operation;
• downloading the encrypted network metadata file from the network to the user device, wherein the encrypted network metadata file comprises data of a filesystem on the network;
• decrypting the encrypted network metadata file on the user device with the network encryption key;
• provided network metadata stored in the network is newer than the updated local metadata file, merging the network metadata file stored in the network with the updated local metadata file to update the local metadata file with data from the network metadata file;
• encrypting the updated local metadata file on the user device with the network encryption key;
• and
• uploading the encrypted updated metadata file to the network.
