Editing a file
Files cannot be edited on the GCwiki. You will need to download the file in order to edit it, and then use a suitable software program to perform the modifications. Once the changes are completed, upload the file to the Wiki. You can use the same filename, which will overwrite the original file.
If other versions (especially a larger version of an image) of the same file exists, link to them.
Files can be in the same category as other pages, but they are treated separately. On the category page files are not included in the count of articles and are displayed in a separate section.
Files can be in the same category as other pages, but are treated separately: on the category page they are not included in the count of articles in the category, and they are displayed in a separate section with a thumbnail of their content.
See category page.
You can categorize the file in the upload summary of the file.
For categorizing a new file, the file page does not even have to be edited: the category tag can simply be put in the upload summary.
