I am having trouble getting the os.path.exists to recognize that a file exists. I keep getting "File does not exist". I reduced the code to the absolute necessary to address my question. I believe everything relevant is in there.

import os
FileName15 ="Stuck"
Folded = arcpy.GetParameterAsText(4)
if Folded == '#' or not Folded:
 Folded = "C:Documents test.gdb\" # provide a default value if unspecified

if os.path.exists(Folded+FileName15+"_table.dbf") == True:
 print ("It does exist")
 print Folded+FileName15+"_table.dbf"
 # Process: Delete
 arcpy.Delete_management(Folded+Name15+"_table", "Table")

 # Process Create Table
 arcpy.CreateTable_management(Folded, FileName15+"_table",Template_Shell, "")

elif os.path.exists(Folded+FileName15+"_table.dbf") == False:
 print ("File does not exist")
 print Folded+FileName15+"_table.dbf"
 # Process Create Table
 arcpy.CreateTable_management(Folded, FileName15+"_table",Template_Shell, "")

  if you copy the full file name, open the python shell and paste it in the parameter for os.path.exists do you get True?

A few things:

1. 
   

   Use "raw strings" to avoid issues with Windows path separators (backslashes) being interpreted as escape characters, e.g.

   
   
   

   Folded = r"C:Documents test.gdb"
    ^ note the r
   

   
   



2. Is there really a space after "documents"? I suspect not



3. 
   

   Use os.path.join() to concatenate paths e.g.

   
   
   

   path = os.path.join(Folded, FileName15+"_table.dbf")

   
   



4. There's no file on the filesystem which directly corresponds to a table/feature class in a gdb, only ArcGIS knows what's in these. What you really want is arcpy.Exists()
