But the curious thing here is that I haven't opened any of these
files, I have merely zipped the folder, copied it to a new PC and
unzipped. (OK, it wasn't ZIP, it was right-click and 'Send to
Compressed folder' but that's just Microsoft-speak for ZIP isn't it?).
Of five Excel files in one folder, four are fine and only one is
'dirty' (is that Tortoise-speak for having a red pling next to it?).
The ok files are dated 2005, 2008, 2009, 2010 and 2010; the dirty file
is dated 2007. I am completely sure I haven't opened that files since
2007 as it's something completely uninteresting to do with that year's
tax return,
In another folder which contains old invoices, about 75% are dirty and
the rest are fine but there seems no rhyme or reason to it. No
correlation by date and as all those invoices have the same format, it
can't be down to the spreadsheet layout. Even more curiously, I
spotted a handful of PDFs with the same problem.
If I copy the file away somewhere and do a SVN update, I get a clean
file but now with today's date which is less than ideal. If I copy
the file back, it's dirty again so you would think that the zip/move/
unzip process must have done something to that file. BUT, if I take
the file directly from my old PC and drag it to the folder on the new
PC, it's dirty again. So it can't be the file - unless Windows 7
modifies the file as I drag and drop it - so it must be what it's
comparing the file against. But wouldn't the update have reset that?
I am out of my depth here!
