Hi.
I have upgraded my laptop from Windows 8.1 to Windows 10. But after upgrading i cannot open one very important xls file which was on my flash drive.
Getting a message saying 'Excel file can not be accessed'.

Any thoughts please?
Thanks

Try the following steps to check the issue:

Check the file permissions：
You can do this by clicking once on the file to highlight it, then selecting "Get Info" from the "File" menu at the top of the screen in Finder, to see if you have "Read & Write" permissions to this/these files.

Check whether your drive have been corrupted, and a permissions repair should fix this if it is the case.

Check to see if it's just a permissions problem by trying to open the file in your text editor. You shouldn't see a nice, ordered spreadsheet when you do this (what you should see is random garbage on the screen), but you shouldn't get an error message about not being able to open the file or files.

Try to copy the file out onto your Desktop and try to open it from there (a copy of the file and not the original), check to see whether it will give the same error message.

 

If that does not work try to repair your Office installation
 

Use 'Open and Repair' Option of MS Excel: For this, open Excel, and then go to 'File >> Open'. Select the file that you want to open, but do not double-click it. Go to the 'Open' drop-down provided in the 'Open' dialog box, and then select 'Open and Repair' option from there. This process repairs the corrupt Excel sheet and opens it normally.
If none of the above mentioned resolutions is able to do any needful to you, then use of Excel repair software is recommended.
