Problem

Error 404 when downloading a page that was exported as PDF, Word, etc.

Environment

Operational System: Windows
.

Steps to Reproduce

Install Confluence on Windows Server and set Confluence Home as root directory. Example: C:\, D:\, E:\,...
Create a Page
Export page as PDF

Expected Results

File is downloaded

Actual Results

Error 404

Download URL should be: http://host/download/temp/pdfexport-20211209-091221-1301-5/PageName-091221-1301-6.pdf?contentType=application/pdf

Using the configuration as bellow, Confluence is removing t from temp and this is the download URL: http://host/download/emp/pdfexport-20211209-091221-1301-5/PageName-091221-1301-6.pdf?contentType=application/pdf

During installation when you select a root directory, confluence.home is set at confluence-init.properties for example:

confluence.home = E:\\ 

In confluence-init.properties there is a recommendation to not use backslashes:

###########################
# Note for Windows Users  #
###########################
#
# Each backslash in your path must be written as a forward slash.
# - For example:
# c:\confluence\data
#
# should be written as:
#
# c:/confluence/data

Even if you use forward slash you will see the error.

confluence.home = E:/

Workaround

1. Create a subfolder for Confluence Home

   mkdir e:\confluence-home
   

1. Stop Confluence
2. Edit your confluence-init.properties. Path on your environment is E:\Confluence\confluence\WEB-INF\classes\confluence-init.properties
   1. Adjust confluence.home:

      C:/confluence-Home
      

1. Save file
2. Move all folders from Home to new Home subfolder:

   move analytics-logs e:\confluence-home\
   move attachments e:\confluence-home\
   move backups e:\confluence-home\
   move bundled-plugins e:\confluence-home\
   move confluence.cfg.xml e:\confluence-home\
   move imgEffects e:\confluence-home\
   move index e:\confluence-home\
   move journal e:\confluence-home\
   move lock e:\confluence-home\
   move logs e:\confluence-home\
   move plugins-cache e:\confluence-home\
   move plugins-osgi-cache e:\confluence-home\
   move plugins-temp e:\confluence-home\
   move shared-home e:\confluence-home\
   move synchrony-args.properties e:\confluence-home\
   move temp e:\confluence-home\
   move viewfile e:\confluence-home\
   move webresource-temp e:\confluence-home\
   

1. Start Confluence

Suggestion

Using installer create a validation to avoid user to select root directory, as they can't select Home to be a subfolder of Confluence install folder.
