Issues syncing large Photoshop files

ℹ️ Support
1

Hi,

I am having issues with syncing large photoshop files (around 100mb and up), when saving in photoshop I get an error that the file could not be saved, and I have to retry several times in-order for the save to work. It does not happen everytime, but it occures more often than a successful save.

Also when I check the description panel in the web app, it says that the file was deleted and then created shortly after which results in no versions getting created.

I am unsure what the cause of the problem is, photoshop do save a temp file while performing the save action as described in: https://stackoverflow.com/questions/26846962/tracking-file-changes-from-photoshop-with-filesystemwatcher
Or maybe something else is locking the files.

Here is a log of the common pattern I see when trying to save (edited in order to remove):

Are you using the desktop sync app or doing a direct save via webDAV? What do the server logs say?

3

Hi,
Thanks for the reply, I am using the desktop client 2.3.1 on windows 10.

4

I would have a hard time believing it has to do with file type, so my guess leans on there’s either some locking going on that doesn’t play nice with syncing or you have a cap set on file upload sizes

5

I am also sure it’s not related to the file format but rather a locking issue, the log do say: Error transferring … server replied: Locked(“storage/Image.psd” is locked).
However I am unsure what would cause the server to lock the file, and if I can do something to prevent it.

I added the full logs in the first post, expand the summary to see it.

Nextcloud typically locks files during file operations. How large is your photoshop file? Can you test with a very small one as well?

Hi,

Thanks for the reply, the issue occurs when the file reaches around 100mb and upwards, small files do not have the same issue, they work just fine.

When the Photoshop file gets larger, photoshop saves a temp file which it writes all the data to and then presumably renames the temp file to the actual output file (many adobe applications works this way). I am unsure if this is the cause of the issue.

8

Do other non-PS 100MB+ files have the same behavior?

9

The desktop client still has this issue. What happens is that during that temp saving period the desktop client deletes the actual .psd file therefor one cant save the .psd file anymore, Photoshop tries to save as a non existing file so it brings up the new file save dialog.

The desktop client has no awareness of PS creating a temp file (and then renames it) to save the actual file and this is a big problem.

Here is the prooof of what is happening, bear in mind, I am in PS saving a file. I did not delete any files druing this period.

The desktop client normally just propagates deletions that are done either on the client (-> then propagates the deletion to the server), or from the server (if it was deleted on the server or by a different client). If you move a file outside the sync folder of NC, it is like a deletion because the changes are not tracked any more.
If a file is copied, that shouldn’t trigger any deletion.

Question is now is the Client doing something wrong and deleting the file?
Or is there something done by Photoshop’s moving/copying around, that looks like a deletion but is actually very temporary, which then could perhaps be better handled somehow by the desktop client.

The file size is relevant only because the client acts way too fast before the whole PS cycle is done. This might not be an issue with files that are small enough that the client cant act fast enough. In the image above, “you created xxxx.psd” is when I save the .psd file again as a new file since the original has been deleted by the NC client.

I literally struggle with this hundred times a day since I need to save large .psd files regularly.
