My biggest think about this is also sharing code between projects, but Rust's target folder is far too big to sync.

As I use Proton Drive to store code for projects I need the ability to exclude folders such as node_modules and .next. This causes me significant issues and time wasted.

Yes, selective sync is really important for many people.

Completely agree. It's incredible this is even an issue especially when one pays so much for the service.

Being able to filter through subfolders you may not want synced would be an absolute game changer.

This actually causes problems with apps like Steam. Since a lot of a save game data goes to the Documents\My Games folder, your cloud Steam save data and Proton Drive save data can get out of sync causing a Steam to hiccup when trying to sync your game data. I love the idea of being able to add things like .gitignore but also being able to list and uncheck subfolders to quickly add those specific folders would be really good. I don't want my Skyrim save game data to sync with proton, but custom files in a Documents\Skyrim folder should sync.

As a developer wanting to store some projects, this is pretty important. the easiest would probably be to just have a setting for setting names with wildcards. But supporting .gitignore files in addition would be even better.

Some of the biggest offenders are eg node_modules for nodejs projects, and all kind of build/dist folders

This is the only thing preventing me from getting Proton Unlimited.

Absolutely critical feature.

I would also say this is a must have. For devs there could also be an option to just obey .gitignore.

It's been almost a year since this enquiry was posted, and Proton has ignored this feature ever since. Despite this, there are almost 500 users who want this to happen. It's the same old story. Proton is just like every other service now: you can request a feature, and they can either ignore your wishes or make one every year. Then they put on a big show, as if they're doing something special to meet their customers' needs.

Definitely need this as an option. Not all files/folders I need to sync to desktop.

Hello, this feature would be extremely usefull!
And both: exclude folders, and exclude files (with wildcards).
For instance,
- in my folder "My documents", I have folders created by apps that I don't want to save
- I also have source code folders which contains generated files which don't need to be saved.

This is a MUST HAVE. ALL of my sync error are from locked files in a folder I need to exclude!

This missing is what is preventing me from fully migrating to Proton. I am using MEGASync, and they have an excellent implementation where you use a Regular Expression. You can specify a full path, partial path, folder/file name, part of folder/file name, etc. You, of course, have to understand how to make expressions. I don't like MEGA and want to switch away from it, but can't until this feature is implemented.

Critical feature! Otherwise I can't store all my data in my proton drive. It would kill my local hard drive!

Critical feature to me! I have a few programs that create subfolders in a folder I want to sync, but I hve no need to sync these subfolders...
Moreover, it would be nice if the "hidden" folders are NOT synced.

Can't believe this isn't even a thing, and has this little votes compared to other features!

I agree with this. I work with design and 3d software and they have "lock files" . For example, Adobe InDesign has .IDLK files which aren't necessary to be synced.

the Proton Drive App even stops syncing when a file is found that is unknown. Also the fact that a file is not automatically skipped when in use by another program is strange. with this the ProtonDrive is really unuseable.
