+### Issues uploading files or failure during writing data
+
+You may have run out of space on the Unix Filestore (T: drive).
+
+Check your quota:
+
+```
+system("quota -s")
+```
+
+It will tell you the space you are using, your quota and the limit, then the number of files, 
+the quota for that and the limit for that. If you are using too much space or too many files 
+you won't be able to add more until you delete some.
+
+If this is not the problem, please [get in touch with RC support](../Contact_Us.md) and tell 
+us:
+
+* How large are the files that are failing to upload?
+* What browser are you using to do the upload to RStudio? Does it work better if you use 
+  Firefox instead? (It is also available on Desktop@UCL).
+
+There is a potential workaround when browser uploads are failing but you definitely have space.
+You can try uploading your data using scp to Socrates or Aristotle and then accessing it from
+RStudio once it is already there.

+* [Transferring files with remote computers (Moodle)](https://moodle.ucl.ac.uk/course/section.php?id=852836)

+Make sure the system you are transferring files to is Socrates or Aristotle, not Myriad.
