We are having an issue when we upload a file to our website in that it is not renaming the file correctly and is crashing out.
The original file is successfully uploading with its original name but is not renaming to the value we want. Is this because the file is not fully uploaded before trying to rename it ? or is it our renaming convention that is causing the issue do we need to use UUID function maybe ? The security on the folder it is uploading to has more than enough permissions, heres the code:  -

<cfif IsDefined("Process")>
<CF_Random_CVIDGen LENGTH="10" CHARSET="AlphaNumeric" UCASE="yes" RETURNVARIABLE="CVUniqueID">

<cfif form.CVFile neq "" and #UserDetails.CVLink# eq "">
<cfif cgi.CONTENT_LENGTH lt 200000>
<!--- first actually upload the file --->
         <cffile action="upload"
                 filefield="CVFile"
                 destination="D:\WWWRoot\www\uploads\"
                 nameconflict="Makeunique">
        <!--- now create a temporary holder for the attachment later on --->
        <cfset Filename = "#cffile.clientfilename#">
            
            <cfset acceptedExtensions="doc,txt,text,rtf,pdf">
            <cfset ext=ListLast(cffile.ServerFile,".")>
            
            <!--- check the file types of the file --->
            <cfif not ListFind(acceptedExtensions,ext)>
<cffile action="delete" file="D:\WWWRoot\www\uploads\#file.ServerFile#">
                  <cfset errormessage = errormessage &
                  "<li style=color:red><font class=mainBlack>Please attach a valid CV.</font></li>">
            <cfelse>
            <!--- its a good file --->
            <cffile action = "rename"
                     source = "D:\WWWRoot\www\uploads\#file.ServerFile#"
                     destination = "D:\WWWRoot\uploads\#UserDetails.Email##CVUniqueID#.#serverFileExt#">
                        
            <cfset FileUploaded = "D:\WWWRoot\uploads\#UserDetails.Email##CVUniqueID#.#serverFileExt#">

            <cfquery name="UpdateCandidates" datasource="Datasource">
            update Candidates
            set CVLink = '#FileUploaded#',
            Filename = '#Filename#',
            CVUpdated = '#DateFormat(Now(),"dd/mm/yy")# #TimeFormat(Now(),"HH:MM:SS")#'
            where CandID = #SESSION.Auth.CandID#
            </cfquery>
            </cfif>
            </cftransaction>
      <cfelse>
            <cfset errormessage = errormessage &
            "<li style=color:red><font class=mainBlack>File too Large. Cannot be greater than 200kb.</font></li>">
      </cfif>
      <cfelseif form.CVFile eq "" and #UserDetails.CVLink# eq "">
       <cfset errormessage = errormessage &
            "<li style=color:red><font class=mainBlack>Please attach your CV.</font></li>">
      </cfif>

It is highly likely that it is your naming process.

Have your tried hard coding in a name of the file and running an upload.  If this works then it is definatley your naming convention.

You could also try doing a MOVE instead of a rename - which would in effect do the same thing, but may work when renaming doesn't.

******* here you save the file with a unique name *******
        <cffile action="upload"
                 filefield="CVFile"
                 destination="D:\WWWRoot\www\uploads\"
                 nameconflict="Makeunique">

******* Name of the file uploaded from the client's system, so you are setting the variable filename to the original filename not the uniquely renamed file, I think you are looking for cffile.serverFile here *******

        <!--- now create a temporary holder for the attachment later on --->
        <cfset Filename = "#cffile.clientfilename#">

******* Or should file.serverfile not be cffile.serverfile *******

<!--- its a good file --->
          <cffile action = "rename"
                  source = "D:\WWWRoot\www\uploads\#file.ServerFile#"
                  destination = "D:\WWWRoot\uploads\#UserDetails.Email##CVUniqueID#.#serverFileExt#">
                   
Thats just a quick scan through the code, I could be wrong.

You asked:  "Is this because the file is not fully uploaded before trying to rename it ?"
- no, the file must be uploaded before it get's it's name returned by coldfusion (#ServerFileName#.#ServerFileExt#)

Once it is uploaded, check for it's existence, then rename it:

<!--- if the file exists, rename the file --->
<cfif fileexists("#directorypath#\#ServerFileName#.#ServerFileExt#")>
<cffile action="rename" source="#directorypath#\#ServerFileName#.#ServerFileExt#" destination="#directorypath#\somenewfilename.#ServerFileExt#">
</cfif>

Of course if the file does not exist then there are problems to be dealt with first. I know you said you have permissions enabled, but if you do not have the right, this stuff won't work, and you may not receive any error messages as to why it's not working.  Permissions problems sometimes tend to blackhole problems, leaving you with few clues as to what happened.

cheers,

Jason

this is what ive used ...

<!---
1. New_FieldName = name of ur file_field on the previous page inside the form tag
2. Image_FieldName = name of the exisiting image
    [used only for deleting previous rec / id can also be used. alter the query below as required]
3. FilePath = full physical path where file needs to be uplaoded OR is uploaded
4. New_ImageName = variable used for assignign new name to the file after uplaod
    [incase of rename option being used]
5. FILEEXT = the extension of the file uploaded - so renaming can be handled properly
6. NewFileName = incase u wanna rename the file- the file uplaoded gets renamed with this value.
