Hmm! Not seen that before.
Do you have access to your database to see if the jD tables are still present - they have names like xxx_jdownloads_categories, xxx_jdownloads_files and so on where xxx is 'prefix you choose initially for the database when installing Joomla.
there are 7 tables. If at sometime in the past you upgraded from jD 3.2.69 there will be a further 8 tables whose name ends in _backup_3_2_69 .
Also go to Extensions - Manage and select Manage from the drop down.Then in the search field enter jDownloads and click on the magnify symbol. This will list isf anny of the jD component, modules or plugins are present.
Also check the root directory to see if there is a jdownloads folder. If the folder is there then it will have directories coresponding to the jD categories.
The look in the root directory for the images directory and see if there is a jdownloads directory present
When you have that info let us know so we can advise the best pathI will also send you a Private Messege (PM)
