Question about job using powershell steps then SQL DTSX File

I have a simple SQL export to an XLS file. To keep the file clean, I have powershell steps:

1. Deletes the current file
2. Copies a template to the location

then runs a SQL step running a DTSX file that does a simple query and exports to the file.

when I run the DTSX file step it works fine, however after I run the two powershell steps it somehow permanently breaks the DTSX step, even if I run the job at that step only.

The only thing I can think of is I had to do set-location C: on the two powershell steps to have the code work, after i changed this the DTSX step constantly fails till I build it again, upload the new file, then it works until I run all three steps again. Any thoughts? I guess I could just build this in Visual Studio instead of using Powershell.

I tried to make the DTSX clear out the spreadsheet before it exports but that always failed, not sure if this is the way to go instead?

Step 1 (works every time): Set-Location c: Remove-Item -Path ""

Step 2 (works every time): Set-Location c: Copy-Item -Path "" -Destination ""

Step 3 (only works if I run it before ever trying the two above steps) Type: SQL Server Integrations Service Package Package Source: File system I made it using a simple Export Data task.

Error after running the powershell steps, when running the DTSX step:
