During a checkout of a Subversion tree on my Windows 7 installation I got quite a fair share of errors from TortoiseSVN, all of which ended with
The file or directory is corrupted and unreadable.
After digging around a bit, I came across this blog post on the exact same problem. And subsequently I found there is a hotfix available from Microsoft on their page about . This hotfix will be in the upcoming service pack 1.
You might also be able to work around it by disabling indexing on the particular folder or drive. It solved it for me at least.
If you like to have a visual cue for, say, where the 80th column is then this page over at Stack Overflow details the various registry keys you might need to add as well as showing which extensions can do it for you. For VS 2010 Professional and up you can use the Productivity Power Tools, but it seems that Visual Studio 2010 Express has no guides support.
For many programming languages we still like to use either 80 or 120 columns in our editors to ensure it fits easily on print, as well as to use it as an aid for ensuring concise code.
In Sublime Text you can set vertical rulers for this by going to
Preferences » User File Preferences and add
rulers 80 120 and save the file.
For Sublime Text 2 it’s under
Preferences » Settings — User, but the configuration file is now in JSON format, so you need to add
"rulers": [80, 120] and maybe you need to append a comma at the end if you have more configuration directives following it.
Addition 2013: in Sublime Text 3 it is still under
Preferences » Settings — User and the file is still in JSON, so simply add
"rulers": [80, 120], like in the example for Sublime Text 2.
