Receiving message " Error: detecting hexadecimal error value 0x00 is an invalid character. Line 1, position 1" when trying to open an existing file.

Question

I saved and closed a file last night, but couldn't reopen it and get the message Error: detecting hexadecimal error value 0x00 is an invalid character. Line 1, position 1. 
 I tried to open the file with excel and Notepad++, but nothing appears in the files that were created. 
 I also tried to open a new translation project with the TM created for that file in Studio, but only a number of segments were saved in it, not all the work done. 
 I tried CCleaner as it was suggested in another thread, updating and restarting Studio, saving the file on my desktop; nothing worked. 
 Can someone help??

 Assuming you know what you were looking for in an SDLXLIFF (and assuming this is the file you opened as you didn't say) try checking the sdlproj file instead. It may be that the project file is the one with the problem and not the SDLXLIFF. 
 You might also find copying the SDLXLIFF to another location and then opening it as a new single file translation will help you resolve te problem, especially if the issue is in the SDLPROJ, or even in the projects.xml.

Hi carine luys 
 When I looked for the NULL character with Notepad++ in the past, this worked: 
 
 Just in case it's a help. Seems less drastic than deleting files...
