GreatMarko

You didn't provide any details as to the total number/size of files & folders you've added to sync... but are you running Sync as a windows service, and therefore you're seeing the "stop running script?" prompt in your browser, or are you running sync as a regular application (i.e. and access the UI via the Sync taskbar icon) If the former, what browser are you running? Have you tried accessing the WebUI via a different browser? If the latter, what version of Internet Explorer is installed on your system? ...and is it up-to-date?

You don't say what OS you're running, but have you tried increasing the folder_rescan_interval setting (i.e. so that Sync re-scans folders less frequently) You could also try adjusting other settings such as setting "disk_low_priority" to "true" in order to concede resources to other applications, etc Also, are you using encrypted folders? If so, these will consume more CPU, so you could consider removing and re-adding these are regular folders instead.

1) Check the system clocks on all your devices are correct/the same 2) Check that when you modify and save a file that it doesn't remain "locked" by the application you have the file open in until you close the file/application (sync can't transfer files whilst they are locked/in-use)

Check the system clocks on your devices and the modification time on the files themselves. Sync has determine that these files have invalid modification times (i.e. they appear to have been modified in the future - which isn't possible). Correcting your device's system clocks (if that's the case) should resolve the issue, otherwise, you'll need to "touch" (modify) the files in question on a device with a correct system clock so that the files then have a "valid" modification time, and can sync.

You don't need to "perform a manual cleanup" of the archive folder - there's a setting in Sync (sync_trash_ttl) that automates this. By default, files will persist in the archive for 30 days, but you can increase/decrease this to suit your particular needs

Connection via relay server will be used in instances where direct connection between peers cannot be established. For more information on when the relay server is used, please see: https://help.getsync.com/hc/en-us/articles/204754779-What-is-a-Relay-Server-

Sync and Sync Pro can use a tracker, but can't install a "local tracker service" The link to information on the tracker options within Sync/Sync pro may be found here: https://help.getsync.com/hc/en-us/articles/205458125-Folder-Preferences

Feel free to post this specific request (i.e. per-folder sync scheduling) over in the Feature Request forum.

IPs, MAC Addresses, and Sync version info can be viewed for your connected devices via the "My Devices" icon

Not if you set all your devices to "Disconnected" mode - that way, when you add a new folder on one device, it won't automatically sync with all your other devices. You can then copy the sharing link to share the folder with your "friends"

You can already share in the way you desire - you can link all your devices (i.e. "My Network" in your images) and add folders that will sync between your own devices, and then "Share" any of these folders with external people (i.e. your "group of friends") See: https://help.getsync.com/hc/en-us/articles/204790709-Sync-Share-Dialog-Desktop-

..and merged into existing feature request thread on this topic(!) @Illuvatar Feature Requests should be posted here in the Feature Request forum, and before posting a new suggestion, please take a few seconds to search to see if your suggestion has already been made and if so go ahead and add to that thread, rather than creating a duplicate thread.

Collecting Debug Logs However, it would first be worth opening your Windows Task Manager and seeing what your CPU utilization is - mouse "lags" usually happen when the CPU is running maxed out. The Task Manager will allow you to identify which process is hogging the CPU... be worth checking that it is actually Sync that's the culprit.

Have you tried the Sync Help Center? i.e. please see the article Peers aren't connecting

Have you tried looking in the debug logs? (sync.log) (you may in fact find that these are TOO verbose for you!)

Thanks, @adriannla a couple of outdated links in the original topic have now been updated.

Sync is designed so as to bring your devices into sync as quickly as possible. It is essentially a "mesh" type network - i.e. all peers can send/receive data from all other peers. Sync will determine the connection speed with other connected peers and use this to determine how much data to send/receive from each peer. For example, if you have 5 peers in your mesh all in sync, all with exactly the same upload/download bandwidth, and you add a 6th peer, the 6th peer will likely receive 20% of its data from each of the 5 peers - this won't be "duplicate" data, this would be different "pieces" of data, the sum of which would make up the complete file/folder. Of course, in reality, not all 5 peers may have identical upload/download bandwidth capacity, or settings, and so some peers may be "faster" than others in your "mesh", and in these instances, Sync may prioritize more data from faster peers than from slower peers. For more on the general background principles behind "Mesh networking", please see: https://en.wikipedia.org/wiki/Mesh_networking

@JimH44 These unofficial packages are for all intents and purposes defunct, as they appear to no longer be maintained by the original author. You'd be wise to instead use the official Linux packages instead, which may be obtained via https://getsync.com

Sounds like a NAT/Firewall issue. Have you checked the NAT/Firewall logs on your router? They may help shed some light on what NAT/Firewall settings need changing.

If you add both to Sync as "read/write" folders, then sync shouldn't delete anything that is on one device but not the other. However, from what I gleam from your question, you wish to sync an ENTIRE drive between PC's? If this is the case, are these drives Windows system drives (i.e. your C: drive), or partitioned/separate drives with no system files on? If it's the former then please be aware that: 1) Sync can't sync files whilst they are open/locked/in use by Windows or another application 2) Some system files & the Windows registry, etc are unique to a particular installation of Windows - attempting to "copy"/sync these to another Windows instance may break Windows! If however, the entire drive you wish to sync only includes non-system files that are not part of your OS, you should be able to sync the entire drive without issue.

Please see this topic.

A list of ports used by sync may be found here: https://help.getsync.com/hc/en-us/articles/204754759-What-ports-and-protocols-are-used-by-Sync- ...although, it's quite likely that your school has blocked all but a limited number of "common" ports (i.e. 80, 443, etc) ...so you'll need to convince your school to unblock/allow Sync through their firewall!

You'll need to apply your Pro license to each of your devices you wish to link under the same license

@p@t0r This initial post in this thread was made back when Sync was developed by BitTorrent Inc, hence the @bittorrent.com email addresses. However, Sync is now developed by a separate company, Resilio Inc. Have you tried applying for an API key via the following link: https://www.resilio.com/api/request-form/ ?
