You would have to open it in Excel and see what happens.
You can use various online free software that can help you convert PDF to various formats including document and excel. To use the software, you can upload your excel file on the website, the website converts it into the desired format and emails the converted file or you can download the converted file from a link.
For some reason, your computer may be set to use Excel as the default program for your music files (no way to tell why or how it happened). To fix the problem, go to windows explorer and right click on the song file. Select the open with option and look to see what program is set to open the file. If it is Excel, then follow the instructions in the open with dialog box to change it to the program you want to open the file. If it is not excel, then you would need someone who knows about computers to look at your computer to see what is going on.
The only thing that is useable is a written contract.
No. They can tell you what software the file was created by, or to be used by. It will not tell you which computer it was made on.
There are good arguments both for and against disabling this option. If file extensions are not shown in explorer, renaming a file will not affect its extension. If an extension is accidentally removed, the file will not invoke the correct application and will not be useable until its extension is reinstated. If you cannot remember the correct file extension, you may not be able to reinstate the file. However, where you are trying to identify a file's extension, having them hidden can cause problems. The only indication of a file extension will be the icon displaying the application that it will be run under. Where you have several file types that run under the same application, it can be difficult to tell one from another without being able to see their file extensions.
File extensions just tell your computer which program it needs to open the file. They also tell you what sort of file it is, for eg: If you got an email and there was an attachement called Sarah.jpg because of the .jpg at the end you know it is a photo file.
Go to the Help menu and look at the About option which will tell you. The version of Excel you have is linked to the version of Office you have. If you know what version of Office you have, then you know what version of Excel you have.
This is the default behavior in most (all?) versions of Excel. You have to go out of your way to tell a spreadsheet NOT to do this.
The file extension tells about the type of file, with the extension three letters. For Eg:- *.txt -- text file *.exe-- executable file
There is no way to eyeball a file and tell if it is a virus. Use a good antivirus program and let it do the work for you.
you guess
If you place the mouse over an icon, it will tell you what it is. This is a tool tip.
