Our sugarcrm directory size is growing, we found this is because old patches or upgraded package.
Can we remove it?
Is there any problem if we removed it?
Deleting old patches or upgrade packages will not be a problem as far as you make sure that you are deleting the right files. I think if you delete the module loader packages then it would be a problem. Before doing anything like that, I would suggest you try it on backup or local copy of the production server.
As Junaid suggested, upload directory contains many files like your uploaded attachments in sugar from Documents and Notes modules, your import files, uploaded packages, packages from module builder etc.
upload/upgades directory contains all your uploaded packages. If you remove any package from here, you won't be able to uninstall that package using module loader. So, if you are sure that you won't be uninstalling those packages, you can go ahead and delete those stuff.
Note: As suggested, always keep a backup before deleting any file or folder.
