I worked on a word document for a couple of times and I saved it on a usb. I could open it but today, I couldn't find the document but there was a fseventsd-uuid file so I opened it using word and it said AB8C7920-7398-4ABA-90AE-B2565A02F51E on the word document



The word document is really important to me
Anyone know how to solve this problem?

A time machine would be very helpful. Sorry.
Word does not play well with flashdrives or other removable media. Never has. Using Word with a flashdrive is currently the number one way of corrupting a document.

For future reference, do not use Word directly with anything on a flashdrive. That means do not open a document on a flashdrive, do not print a document on a flashdrive, do not save a document to a flashdrive from within Word.

With the document closed, use the Mac Finder to copy to/from the flashdrive and your hard drive.

Just out of curiosity, why does Word have problems with flash drives? according to the wikipedia article, these have been around since the turn of the century; and used by Windows from Vista onwards to add system memory. OK, so we know flash drives can die between one write and the next … but that's surely not application-specific?

My understanding is that it has to do with Word's temporary files. I do not know the reason, just the result.
